  1. 1. Spatiotemporal changes in Gothenburg municipality's green space, 1986 to 2019

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Kristin Blinge; [2021-04-01]
    Keywords : NDVI; multitemporal change analysis; incremental change; urbanization;

    Abstract : As the world’s population is becoming increasingly more urban the infrastructure expands to accommodate the inhabitants’ needs. In a dense urban environment green space has an important function since it provides vital ecosystem services, contributes to recreational and cultural values and is essential for biodiversity.

  3. 2. Carta ex Machina: Testing object-based machine learning and unsupervised classification in land use change detection mapping in the semi-arid governorate of Sidi Bouzid, Tunisia

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kristian Emil Havnsgaard Paludan; [2021]
    Keywords : Change detection; Land use mapping; LANDSAT MSS; LANDSAT TM; GEOBIA; Random Forest classification; ISODATA cluster classification; Object-based classification; Semi-arid agriculture; Irrigation mapping; Earth and Environmental Sciences;

    Abstract : Sidi Bouzid, Tunisia is an inland governorate in Tunisia that has undergone a rapid agricultural and urban development since the Tunisian independence in 1952 from being a rural and largely nomadic region into a hub of irrigated agriculture. In 2010 Mohamed Bouazizi sparked the Tunisian revolution by lighting himself on fire int he city of Sidi Bouzid, with some blaming the inequality and water scarcity created by this rapid expansion in the irrigation farming as an important cause (Bayat, 2017; Malka, 2018).

  4. 3. Tracing mangrove forest dynamics of Bangladesh using historical Landsat data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Md Monirul Islam; [2017]
    Keywords : Bangladesh; Physical Geography and Ecosystem Analysis; Landsat; mangroves; change detection; time-series; NDVI; supervised classification; Earth and Environmental Sciences;

    Abstract : Present, accurate, and reliable estimation of mangrove forests in Bangladesh is limited. Former estimation of mangroves extent and density has been more or less restricted to Sundarbans and do not represent the whole country. READ MORE

  5. 4. Forest Change Mapping in Southwestern Madagascar using Landsat-5 TM Imagery, 1990 –2010

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Jeroen Grift; [2016]
    Keywords : Deforestation; pixel-based classification; object-based classification; landscape metrics; scaling structure;

    Abstract : The main goal of this study was to map and measure forest change in the southwestern part of Madagascar near the city of Toliara in the period 1990-2010. Recent studies show that forest change in Madagascar on a regional scale does not only deal with forest loss, but also with forest growth However, it is unclear how the study area is dealing with these patterns.

  6. 5. The suitability of using Landsat TM-5 Images for estimating chromophoric dissolved organic matter in subarctic Lakes

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Jakobsson; [2014]
    Keywords : CDOM; dissolved organic carbon; colored dissolved organic matter; Chromophoric; landsat thematic mapper 5; subarctic lakes; Stordalen; empirical algorithm.; Abisko; DOC; remote sensing; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter (CDOM; a proxy for DOC) from the easily accessible satellite images Landsat TM-5, to counter the inaccessibility of the region in general.
