GIS development in Alvesta municipality

Note! This text has been machine-translated from Filegis_alvesta_2018-01-09.docx

Alvesta municipality with approximately 20,000 inhabitants - southern Sweden's center. Our starting point is local accommodation with global opportunities. There are good living environments close to both the city and the countryside and rich opportunities for active leisure.

The map and GIS operations are located under the Civil Planning Administration and work closely with the units plan, engineering, construction and the environment. We have a municipal license for ArcGIS and Geosecma, which means that we have access to many useful tools in ESRI's service catalog.

The need to make available geodata and simplify the use of the map in the daily work is great. The many internal webGIS we have today are heavy and complex, which means they are good for experts, but not for generalists. We are in the process of initiating the development of a webGIS that will provide a quick viewing service for internal users. In the long run, hopefully the service can also be used externally to the public via our website.

Our needs are to be able to obtain a map service containing several basic maps, such as the municipality's primary map, the topographical map of the survey, etc. and several orthophotos, including the current orthophoto and the historical orthophoto of the land surveyor. On the map services, we need to report property data and be able to link to search and identification of properties against the land survey property information. Furthermore, we need to be able to present municipal data in the form of detailed plans, pipelines etc. We also want to be able to build on more layers of geodata, including government plans and knowledge bases / inventories.

The service needs to be smooth and have a simple and clear interface.

The service can be developed either with scripts (such as https://cmv.io/en.us.) Or with ESRI's products.

Air pollution monitoring with Earth observation satellites

Air pollution is the world’s deadliest environmental problem. It kills seven million people each year, or one in eight deaths globally [1]. Satellite remote sensing of air quality has evolved dramatically over the last decade. Global observations from Envisat satellite, NASA’s Aura and Terra missions, and most recently ESA’s Sentinel-5P satellite mission [2] are now available for a wide range of species including common pollutants in surface air (e.g. aerosols, ozone, nitrogen dioxide, carbon monoxide, and sulphur dioxide) [3]. But these observations are either not available in the form of end-user data products or, if they are, they basically have different properties (e.g. spatial and temporal resolutions, spectral range and resolution) which both make it difficult to choose and generate data series of a specific pollutant for a specific region.

This project aims at developing methods to generate time series of the main air pollutants form EO satellites at a regional scale. Such reliable data series enable estimation of spatio-temporal variability in air pollution concentration and its association with other relevant factors such as land use change, traffic volumes, and health parameters etc., considered as the second aim of the project.

The ideal candidate is a (geomatics) student who has passed advanced remote sensing and GIS courses, and has experience or is interested in data processing and programming.

Forest degradation caused by small scale farming


While a lot of focus is placed on negative effects of forestry and e.g. oil palm plantations in tropical rain forest areas, less attention is paid to forest degradation by small scale farming. However, especially in areas with high human population densities, small scale farming can be a major driver of changes of intact forest cover, and sometimes even in protected forests.

In this project an analysis of the extent of forest degradation caused by small scale farming inside and near protected forests in tropical Africa is to be performed.

During previous field visits, field data on small scale farm clearings, together with estimated times since clearing (ranging from 2-10 years in most cases), were collected for ca. 40 points. From the RS group in Maryland yearly cloud free Landsat composites covering the survey area have been generated for the period 1984-2016. For the sample points, a time series analysis is to be performed to find the signature of the forest degradation in the remote sensing data.

After this signature has been detected,  a map of forest degradation has to be generated for the area. This theme is suitable for a distance student.

Temporal changes in water levels of the baltic sea in the past and the future


At the island of Langenwerder, the oldest nature reserve in Germany, breeding success of shore birds has been recorded in a systematic manner since the 70s. Shorebirds have their nesting sites very close to the shore. Any short term high water level can destroy their nest and lead to a loss of their eggs or chicks if they are not old enough to run up shore.

Over the last years the breeding success is said to have decreased due to May or June high water levels. The task of this thesis is to find out whether

(I) there has been a change in the frequency of the high waters during breeding season over the last decades and 
(II) whether there is a change to be expected in the frequencies of the high water levels in the breeding season.

Datasets available:

  • measurements of relative water levels at the island (1.5 years). 
  • minute wise water level measurements close by (ca 5 km; 20 years). 
  • daily water levels close by 50 years
  • 2 daily snapshot water levels from a water level projection models for the place (1976-2098).

M.Sc. project: Photo-chemical reactivity of dissolved organic carbon (DOC) in subarctic lakes

Time: Spring 2018, start asap

Photo-chemical degradation of DOC by sunlight represents a poorly studied potential source of globally significant emissions of carbon dioxide to the atmosphere. This project will carry out photo-chemical degradation experiments, and explore the landscape controls of DOC photo-reactivity in subarctic lakes from northern Sweden. An archive of recently obtained samples from more than 100 lakes will be made available to the student. Ultimately, the project will test a set of specific questions related to how climate and vegetation gradients (possibly hydrological factors) influence DOC composition and photo-chemical reactivity.

M.Sc. project: Within and between species variation in root traits along a boreal forest chronosequence

Time: Spring 2018 or as agreed

Plant traits provide a useful way to link community ecology and ecosystem biogeochemistry. But, the explosion of research on this topic has overwhelmingly focused on leaves rather than roots, which constrains both ecosystem understanding and global models. This project would help to fill this gap in our knowledge by recording an array of root traits within boreal forest plant communities along a natural gradient in ecosystem development and soil fertility encompassing 30 islands in northern Sweden ranging in age since major wildfire disturbance from ~50 to ~5000 years. The overall outcome will be an improved understanding of patterns in, and regulators of, boreal forest species traits below-ground.

M.Sc. project: Measuring phenology by UAV camera

Time: spring 2018

The project aims at testing methodology for estimating the seasonal vegetation development (phenology) at high spatial detail by using images acquired from multispectral cameras on-board UAV. The project is part of investigations carried out within the SITES Spectral Thematic Centre for developing working routines for all SITES stations in Sweden. The first task will be to investigate radiometric properties of the multispectral camera. Secondly, flights will be performed together with technical personnel during the growing season, and data will be investigated to elaborate the best methods for estimating seasonal vegetation plant growth.  The student needs to have passed an advanced remote sensing course and needs to be  interested in data processing and fundamental remote sensing.

M.Sc. project: Classifying land cover using high-resolution data from Sentinel-2

Time: spring 2018

This project is about improving the classification of new data from Sentinel-2 satellite. It involves investigating pre-processing (radiometric correction) and testing the effects of this on classification accuracy. This fundamental knowledge will be incorporated in Lund University's operational scheme for Sentinel-2 processing. The project also involves testing of different band combinations, time-series data, and applying novel machine learning algorithms. Validation data will be collected mainly by aerial orthophoto interpretation. The student needs to have passed an advanced remote sensing course and needs to be interested in data processing and fundamental remote sensing.

Map and analyze pristine ecosystems in Sweden or globally

The proposed project is a part of a larger research project that addresses questions on climate mitigation by reforestation or extended use of bioenergy. The project would focus on producing key datasets on the location of pristine ecosystems (an ecosystem largely unaffected by humans) and important information about these ecosystems. The scope can be varied to include Sweden, Scandinavia or a global dataset, most important is the production of quality data that can be used in research to which the student would contribute.

The student would work independently and the following steps are anticipated:

  1. Perform a literature and data search of information on pristine ecosystems. Collect information on pristine ecosystems, this can include digitizing maps in paper format, or collecting various digital datasets on pristine forests, depending on what is available. Multiple datasets that are differentiated by the origin or type of data would be ideal and depends on what is available.
  2. Collect important information on the pristine ecosystems, this includes but is not limited to; time since last human disturbance, biomass, soil carbon content, biodiversity metrics, ecosystem type and environmental information.
  3. Perform initial analysis on the data, this depends on the students interest and ideas and could include investigation of the pristine ecosystems such as their age and extent. If time allows it could also include more advanced analysis on the difference between pristine and managed ecosystems, such as investigation of carbon storage in vegetation and soil, productivity, leaf area, biodiversity etc.

The ideal candidate is a driven student that is prepared to work independently and wants to contribute to a research project as an integrated team member. This contribution could include the use of the dataset and analysis performed in a larger study. It could also include the writing and publishing of a scientific paper.

The scope of the project and analysis can be adjusted to the type of thesis (bachelor or master) and it is also possible to divide the work between multiple students. The project is not limited to the allocated time allocated for the thesis; it could start earlier and continue after.

M.Sc. project: Carbon dioxide exchange at Hyltemossa ICOS site

The ICOS (Integrated Carbon Observation System) research infrastructure is a new European research infrastructure which will provide researches with data on ecosystem scale carbon fluxes in 13 counties. ICOS Sweden is operating 6 ecosystem stations ranging geographically from Skåne to northern Swedish Lapland, and covering forests, wetlands and agriculture.

The Hyltemossa station in Skåne is situated in a managed Norway spruce forest. The flux measurements conducted routinely at the site provide total ecosystem carbon dioxide exchange. The proposed project is to quantify the contribution of ground vegetation to the total exchange. This would be done by conducting measurements using manual soil chamber. The work requires field work over growing season at the site.

Contact: Janne Rinne


M.Sc. project: Representativeness of Swedish (Nordic, European?) flux measurement network in the climate and ecosystem space.

Ecosystem-atmosphere carbon dioxide measurements are done by networks of measurement stations distributed across different ecosystems and climatic regions. However, the locations of these stations may be due to logistical and historical reasons, rather than due to diligent network design. Thus, the representativeness of the network may not be optimal. The proposed M.Sc. project would investigate the representativeness of Swedish flux measurement network under e.g. ICOS Sweden SITES in the climate and ecosystem space. This could be expanded also to Nordic, or European scale. This would be done by analysis of climate data, land use data, and possibly remote sensing data across the chosen study domain.

M. Sc. Project: Characterization of surface fluxes at ICOS Sweden measurement sites.

The ICOS (Integrated Carbon Observation System) research infrastructure is a new European research infrastructure which will provide researches with data on ecosystem scale carbon fluxes in 13 counties. ICOS Sweden is operating 6 ecosystem stations ranging geographically from Skåne to northern Swedish Lapland, and covering forests, wetlands and agriculture. The infrastructure in in starting phase with first official data available in 2018. In the proposed project one would analyze and characterize the surface fluxes of carbon dioxide, methane, sensible and latent heat, and radiative energy across the Swedish ICOS network. The aim is to produce a first synthesis on the similarities and differences of the surface exchange processes in these sites, and where possible compare with older datasets.

M.Sc. project: Stable isotope (13C) signature of methane emission from wetlands in relation to production, oxidation and transport.

Carbon-13 is a natural stable carbon isotope making up 1.1 % of carbon on earth. Its slightly higher mass as compared to the more abundant carbon-12 leads to slight differences in its diffusion and reaction rates. Thus, small differences in carbon-13 signature (delta13C) in e.g. methane emissions can be indicative of different processes in play. In the proposed project one would look at differences in delta13C in methane emitted from microtopographically different wetland surfaces, as well as d13C in dissolved methane, and delta13C in nocturnal boundary layer for ecosystem scale signal. The aim is to constrain the mechanisms resulting in different flux rates from different peat surfaces and to advance upscaling of methane emission to ecosystem scale. The project requires field work during summer, probably near Vänersborg.

Master’s thesis work

Topic: Measuring planktonic CO2 production and O2 consumption rates in the water by using automatic under-water chambers

When: Suggestion 50% during 2017

What: Surface water respiration represents one of major processes on earth which transforms organic carbon into CO2. Most assessments of aquatic respiration are based on models using the daily oscillations in open water gas data. However, several assumptions need to be made to operate these models, some of which are uncertain. Surprisingly few direct measurements of water column respiration exist. This project will test a prototype of an automatic under-water chamber which opens and closes on given intervals, logging the CO2 production and O2 consumption rates in the water around the clock. A “handy” student is sought, interested in taking part in building and testing a raft with mechanics needed to open and close a chamber equipped with gas loggers. Due to the nature of the work (waiting for parts to arrive, season for field testing etc), part-time commitment during two semesters is ideal, spanning a summer. Therefore, the project is suited for a 50% pace student, or someone who can do part of the project in summer.

Vegetation productivity trends across global drylands using different satellite sources


This purpose of this project is to quantify and understand the role of dryland ecosystems in the global carbon (C) cycle. Recent work show increasing importance of drylands in the global C cycle [1-3] and regional studies using Earth Observation (EO) report increasing greenness in several dryland areas [4-9]. While the increasing role of drylands in the global C cycle is well-grounded, is the knowledge regarding the related magnitude, spatial, temporal variability and process understanding still uncomplete [10].

This project aim to quantify the temporal and spatial characteristics of C fluxes of drylands and their contribution to the global C cycle using EO data (MODIS time series of PPI, EVI,NDVI based on the BRDF corrected MOD43A4, latest collection, MOD17 GPP and NPP etc.). The EO data will be stratified using biome data sets, the aridity index etc.

Suitable for student with interest in remote sensing, GIS and the global carbon cycle. Programming skill is a benefit

Afforestation of southern Sweden pastures, mapping, cause and effect

This work aims to identify and quantify the land use changes in the form of pastures planted with forest.

Background: In areas where profitability to keep animals is marginal, a conversion of pasture land to forest land by planting both leave forests and pine forests. This implies a change in the landscape, affects the production of animal products (meat, milk, cheese, etc.) and affect biodiversity and occasionally other ecosystem services. The reasons for this change is, among others, lower profitability in the livestock sector.

Master thesis work

Contact: Emma Li Johansson

Background information: Currently there is a wave of foreign investments in land taking part in the economically poor regions of the world. These particular types of land investments affect people who previously used that land as small-scale farmers, who often have no other option than to keep farming in smaller or more marginal areas around the foreign investment.
 
Topic #1: Socio-environemtal effects from land-use change in the context of large-scale land acquisitions
Large-scale land use changes affect the water balance, especially when land cover is changed to water intensive crop production. Land-use change affects the quantity, quality and accessibility of water for people and ecosystems in those areas. Either directly through irrigation, or by planting non-native crop species that dry out the soils. Accessibility to water is also affected by fragmenting the landscape and making traditional water sources inaccessible or unusable to local communities. I have both quantitative and qualitative data (or knowledge about where to look for data) from large-scale land acquisitions in Sierra Leone and Tanzania that could form one or several smaller studies:
•    Impacts of teak plantations on the hydrological cycle  (Literature review). Teak trees have effects on water quantity in the way that their roots absorb water and and dries out the soils. They also loose their leaves in the dry season, which dries out soils even more (compared to natural forest). This affects water systems, which in turn affects local livelihoods of fishing and farming. There is a company called KVTC in Kilombero Valley, Tanzania, who are planting 8000 ha of teak where there previously was natural forest . Here you can look at the teak trees' effects on water systems, and how that in turn affects ecosystems and people. 
•    Similar project can be developed with case studies in other parts of Tanzania (rice production,sugarcane production) and Sierra Leone (sugarcane production).


Topic #2 Analyzing past and present land-use in Africa by using Google Earth (in the context of land grabbing)
Research about the scale of land grabbing needs to be improved by analyzing how much land is actually in production. In Africa about 22 million ha has been contracted to foreign investors, but only 3% is currently in production. There is data available online from multiple sources about the current state of land deals, but they are constantly changing as companies often leave their operations or sell to other agricultural businesses. It would be interesting to explore what the previous land use was in areas of land grabbing (e.g. Small-scale farming, forest, grazing land, or marginal land) in order to get a better idea about the potential ecological and societal effects of such investments. 

 


Master thesis work

Topic: MODIS collection 5 vs collection 6. Improvements and differences.
When: January-June 2017.
What: Comparing MODIS collection 5 vs collection 6 for semi arid regions. Data produced by the MODIS is released in collections, the lastest collection is number 6 and it have been produced to increase the quality and reliability of the data. This Msc will look at three aspects 1) Differences in reflectance, 2) differences in time series and trend analysis and the effect of applying LUE models using collection 5 vs collections. Reference data from sites in Sahel is available.

Background: Terra MODIS has no sensor shift issue, the sensor degradation introduced a significant negative trend globally in collection 5 (Wang et al. 2012). This problem has been addressed in the version of collection 6 recently released (Detsch et al. 2016; Lyapustin et al. 2014).

Bachelor thesis work (possibly Master)

Topic: Organic nutrient delivery to the sea
When: As agreed
What: Over the past decades, organic carbon concentrations have doubled in many Baltic Sea river mouths, with consequences for the biogeochemistry, ecology and gas budgets of coastal marine environments. Similar trends have been observed in rivers across widespread areas of the northern hemisphere. However, there is surprisingly little knowledge on whether or not organic N concentrations have increased proportionally with the increases in organic C. Shifts in the relative delivery of organic N, organic C and other nutrient fractions would have large impact on the functioning of estuarine ecosystems in particular. This project will use data from the Swedish national monitoring program for water chemistry to test hypotheses regarding the relative delivery of different organic nutrients from land to sea.

Master thesis work

Topic: Readability of dynamic maps

When: From January 2017. 
What: Most readability studies for maps has concentrated on static maps (on paper and screen), while the actual use of maps is more dynamic today. To design future map services we need better knowledge about how user perceives dynamic maps. This project aims at both studying the theoretical background to reading dynamic maps (based on theories of reading static maps and theories of reading dynamic graphics and animations) and practical studies using eye-tracking (in cooperation with the humanity lab at LU).
Requirement: The work is conducted at the LU campus. The student must be either a geomatic student or an LTH student in geographic information technology.

Master thesis work

Topic: Integration of building information models and geodata
When: From January 2017. 
What: Digitalization is currently one of the main drivers of improving the process in the built environment sector, i.e., planning, creating and maintaining buildings and infrastructure. A main problem here is the integration of building information models (BIM) and geodata/GIS. The aim of this project is to develop methods to import a BIM-model into a GIS environment. This implies work with simplifying the model and transforming it to a geometric representation used in GIS. If time permits the project will also include quality issues in the integration process. 
Requirement: The work is conducted at the LU campus. The student must be either a geomatic student or an LTH student in geographic information technology.

Atmosphere-wetland water balance at a boreal fen

B.Sc./M.Sc. project

The water balance of a wetland is composed of evaporation, rainfall, horizontal water flows and change in water storage. In the suggested project you will analyze how much of the water table (water storage) variations can be explained by the local evaporation and rainfall, and how much can be attributed to horizontal inflow and outflow. The project can be either M.Sc. or B.Sc. thesis, depending on the width and breadth of the analysis. We have a long data set of evaporation, rainfall, and water table position measured at a boreal fen site in Southern Finland, that can be used for the analysis.

We are seeking for a student who is interested in analyzing flux data and other time series data. Skills in Matlab or R languages will be needed in the analysis. Understanding the flux measurements and wetland functioning are assets.

MSc. Project proposal

Automatic detection for the best location of proposed dams using spatial analysis, hydrological modelling, and optimization.

Summary: one of the main approaches for an efficient use of water resources in many regions in the world is to harvest all the runoff water through constructing small to medium size dams. In this proposal, we suggest using hydrological modelling, spatial analyst tools, optimization, and programing to automate the site selection of a proposed dam/s through automatically detect the best location/s for a specific region. Additionally some other hydrological and engineering characteristics of the proposed dams and lakes will be automatically deducted.

The main goals of this proposal are:

  1. Create new computer program
  • To automatically identify all possible sites that can be used to construct a dam for a specific area.
  • To automatically estimate the optimal dam height.
  • To automatically estimate the volume and coverage area of the detained water (volume and area of lake).
  1. To rank all possible sites for dam construction according to general criteria and regional criteria using optimization.

Data needed:

Digital elevation model (DEM) for the selected area.
Regional criteria related to the purpose of the dam/s for that region.

Method

  • MATLAB programing is to be used to calculate: flow direction, Flow accumulation, slope, and aspect for all points in the study area.
  • MATLAB function is to be created to automatically find all possible points for the proposed dams.
  • Optimization is to be used to rank all possible points for the proposed dams according to predefined criteria (Dam height, Volume of lake, surface area of lake, distance from urban area, etc…).
  • ArcGIS is to be used for visualization.

Object-based segmentation and classification of agricultural fields using remote sensing and GIS data

Reliable estimates of areas planted to certain crops and of crop production are needed for:

  • proper planning,
  • monitoring and
  • improvement of the development process and
  • for policy decisions.

Reliable and timely estimation of agricultural production can improve import/export and allocation policy for resources and inputs, such as

  • seed,
  • fertilizer,
  • pesticides,
  • fuel and storage, as well as
  • improve crops natural hazard damage assessment for the agricultural insurance funds.

Recent developments in Earth observation satellites, modeling of crop production processes and geo-information systems have created promising opportunities for upgrading agriculture statistical systems.

However, when accurate mapping of agricultural fields is required, available multispectral classification of satellite data cannot directly yield the information demanded, due to the complexity of real world images.

In this research an innovative applications will be developed in order to extract the required information for monitoring agricultural fields (such as field boundaries and crop type present in a growing season) using freely available remote sensing satellite images (like Landsat 8 data) and ground reference training generated data addressing supervised classification (knowledge-based and object-based).

The available (ground) data for use in the classification process includes, for example, Google Earth, as well as data from farmers (GPS data) and other existing GIS project. The focus of this research will be on developing and evaluating application tools of object-based image analysis that will provide users with up-to-date boundaries of agricultural fields as well as crop type.

Estimating the surface shortwave radiation components using MODIS and field spectrometer data

Accurate estimation of surface shortwave radiation budget is needed for various applications including agricultural meteorology, weather prediction, climate monitoring, and solar power generation. Surface incident shortwave radiation is a significant variable of many numerical models to estimate soil moisture, evapotranspiration and photosynthesis. The most practical and reliable method to capture the spatial distribution of solar radiation is based on remote sensing compared to location based measurements. Over the past years, many models for estimating surface shortwave radiation or its components have been developed from various remote sensing observations by combining remote sensing observations with ancillary surface and atmospheric data. Recent studies have shown that the accuracy of existing models for the estimation of solar radiation was not always satisfactory. In this research, after understanding the available uncertainties in these models through literature study as well as using field spectrometer data, we envisage how the estimation of the irradiance components can be improved. Thus, this research tries to provide accurate solar radiation data based on the data and products from MODIS, on board the Terra and Aqua satellite platforms, as an alternative solution for existing unreliable or limited amount of ground Pyranometer data.

Stranderosion i Skåne knutet till länsstyrelsen i Skåne Län

When: As agreed
What: Någon eller några kommuner som funderar på åtgärder mot erosion skulle kunna väljas ut (t. ex Ängelholm och Kävlinge se länkar nedan). Studenten kan då utifrån kommunernas dokument och genom intervjuer försöka beskriva föreslagna åtgärder och kanske också identifiera några genomförda åtgärder. Efter att åtgärderna har beskrivits skulle studenten utifrån naturgeografisk litteratur beskriva och eventuellt räkna på effekter av åtgärderna och beskriva vilka konsekvenser och påverkan som åtgärderna kan innebära på naturliga processer och kritiskt granska sekundära effekter. Det skulle också kunna ingå intervjuer med olika företrädare för kommunen för att identifiera vem som tar initiativ till åtgärder och vilken litteratur och annan kunskap man bygger sina förslag på och också intervjua t. ex kommunekologer som ju ofta inser konsekvenserna av åtgärder men som inte brukar ses som en viktig del i beslutsprocessen. Eventuellt skulle också effekterna av någon genomförd åtgärd i utvalda kommuner kunna studeras.

Master thesis work

Topic: Evaluating soil wetness in RCM/ RCA-GUESS simulations
When: From January 2015.
What: Focus of this project is on evaluating soil wetness (or in fact focusing on situations when there is lack thereof) in RCM simulations. The background is that there is demand for information on frequency and intensity of ‘drought situations’ in future projections and the possible effects on vegetation. The backbone of the project would be to evaluate a dedicated RCA-GUESS run (done by SMHI) and link various specific soil dryness variables in this run to variables that are more commonly available in standard projection runs.
Notes: Interest in modelling, climate change, regional climate modelling, impacts of dry conditions and skills in statistical/quantitative analysis of regional climate projections. Programming skills in eg. MATLAB for data analysis. Working for a period in Norrköping at the SMHI is a possibility although you have to organize accommodation yourself.
