1. 21. Object-Based Classification of Vegetation at Stordalen Mire near Abisko by using High-Resolution Aerial Imagery

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Marco Giljum; [2014]
   Nyckelord :Physical Geography and Ecosystem Analysis; Object-Based Image Analysis; OBIA; Vegetation Classification; Permafrost; Arctic Peatland; Remote Sensing; Aerial Photography; Environmental Monitoring; Landscape Analysis; Earth and Environmental Sciences;

   Sammanfattning : The focus of this work is to investigate and apply the remote sensing method of object-based image analysis (OBIA) for vegetation classification of a permafrost underlain peatland in sub-arctic Sweden, by using aerial imagery of high resolution. Since the northern landscapes are an important source of naturally stored CH4 and CO2, their contribution to the global carbon cycle is a focus in research about climate change and the global methane exchange.

3. 22. Object based change detection in urban area using KTH-SEG

   Kandidat-uppsats, KTH/Geodesi och geoinformatik

   Författare :Joline Bergsjö; [2014]
   Nyckelord :change detection; KTH-SEG; OBIA; high resolution;

   Sammanfattning : Today more and more people are moving to the cities around the world. This puts a lot of strain on the infrastructure as the cities grow in both width and height. To be able to monitor the ongoing change remote sensing is an effective tool and ways to make it even more effective, better and easier to use are constantly sought after. LÄS MER

4. 23. Byggdelsklassificering av installationer : En fallstudie i hur BSAB-systemet kan utvecklas

   M1-uppsats, KTH/Byggteknik och design

   Författare :Oscar Lindell; David Ström; [2014]
   Nyckelord :BIM; BSAB; classification; building process; design; HVAC; building installations; BIM; BSAB; klassificering; byggprocess; projektering; VVS; installationer;

   Sammanfattning : Building Information Modelling (BIM) medför ett helt nytt sätt att arbeta där objektsbaserade 3D-modeller är den huvudsakliga informationskällan. Modellerna kan bära på stora mängder information i jämförelse med den traditionella pappersritningen som är begränsad till text, symboler och en 2D-visualisering av byggnaden. LÄS MER

5. 24. Radar and Optical Data Fusion for Object Based Urban Land Cover Mapping

   Master-uppsats, KTH/Geodesi och geoinformatik

   Författare :Alexander Jacob; [2011]
   Nyckelord :Data Fusion; Image Segmentation; Object based Mapping; Urban Land Cover; SAR; Radar; Multispectral; Region growing and merging;

   Sammanfattning : The creation and classification of segments for object based urban land cover mapping is the key goal of this master thesis. An algorithm based on region growing and merging was developed, implemented and tested. The synergy effects of a fused data set of SAR and optical imagery were evaluated based on the classification results. LÄS MER

7. 25. High Resolution Satellite Data for MappingLanduse/Land-cover in the Rural-Urban Fringeof the Greater Toronto Area

   Master-uppsats, KTH/Geodesi och satellitpositionering

   Författare :Maria Irene Rangel Luna; [2006]
   Nyckelord :;

   Sammanfattning : Landuse and land-cover classification from high resolution imagery has been seen as challenging by theremote sensing society. The high variability from pixel to pixel makes the use of pixel-based classifiersobsolete. LÄS MER
