1. 1. The World in 3D : Geospatial Segmentation and Reconstruction

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

   Author : David Robín Karlsson; [2022]
   Keywords : deep learning; ai; machine learning; geospatial; gis; heightmap; semantic segmentation; satellite imagery; aerial imagery;

   Abstract : Deep learning has proven a powerful tool for image analysis during the past two decades. With the rise of high resolution overhead imagery, an opportunity for automatic geospatial 3D-recreation has presented itself. This master thesis researches the possibil- ity of 3D-recreation through deep learning based image analysis of overhead imagery. READ MORE

3. 2. Evaluating DCNN architecturesfor multinomial area classicationusing satellite data

   University essay from Linköpings universitet/Artificiell intelligens och integrerade datorsystem

   Author : Karol Wojtulewicz; Viktor Agbrink; [2020]
   Keywords : Segmentation; FCN; Computer Vision; Autoencoder; Area classification;

   Abstract : The most common approach to analysing satellite imagery is building or object segmentation,which expects an algorithm to find and segment objects with specific boundaries thatare present in the satellite imagery. The company Vricon takes satellite imagery analysisfurther with the goal of reproducing the entire world into a 3D mesh. READ MORE

4. 3. Classification of ground lichen using Sentinel-2 and airborne laser data

   University essay from SLU/Dept. of Forest Resource Management

   Author : Helene Larsson; [2018]
   Keywords : remote sensing; random forest; reindeer;

   Abstract : The northern part of Sweden has two overlapping land-use interests: forestry and reindeer husbandry. Forestry affects reindeer husbandry in several ways; most important of these is its impact on ground lichens. Lichens are the primary winter grazing resource for reindeer, therefore, mapping of lichens is of interest. READ MORE

5. 4. Evaluation of pixel based and object based classification methods for land cover mapping with high spatial resolution satellite imagery, in the Amazonas, Brazil

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Linnea Jonsson; [2015]
   Keywords : support vector machine; maximum likelihood; SPOT-5; classification; geography; physical geography; RBF-kernel; OBIA; multiresolution segmentation; Earth and Environmental Sciences;

   Abstract : In the state of Acre, Brazil, there is ongoing land use change, where inhabitants of this part of the Amazonian rainforest practice shifting agriculture. Practicing this type of agriculture is, according to the SKY Rainforest Rescue organization, damaging to forest ecosystems. READ MORE

6. 5. Relationship between tree species composition and phenology extracted from satellite data in Swedish forests

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Stefan Arvidsson; [2015]
   Keywords : MODIS; forests mapping; fractional mapping; satellite derived phenology; GIS; Physical Geography and Ecosystem analysis; TIMESAT; NDVI; EVI; Earth and Environmental Sciences;

   Abstract : This study investigated the “relationship between tree species composition and phenology extracted from satellite data in Swedish forests”. The proposed method investigated in this study aims at mapping the fractional composition of deciduous/coniferous tree species and also the fractional composition of Norway spruce (Picea abies) and several pine (Pinus sp.
