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

   Författare :Luisa Teixeira; [2015]
   Nyckelord :fish biodiversity; coral reef; benthic habitats; object-based image classification; very-high resolution remote sensing; geography; physical geography; Earth and Environmental Sciences;

   Sammanfattning : A Reserva dos Arquip�lagos Primeiras e Segundas, localizada no norte de Mo�ambique, � a maior zona mar�tima protegida de �frica, estendendo-se por mais de 200 km de costa. Apesar da sua import�ncia para a economia local, informa��es sobre os seus ecossistemas marinhos, e particularmente habitats b�nticos, s�o escassas. LÄS MER

3. 12. Urban classification by pixel and object-based approaches for very high resolution imagery

   Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

   Författare :Fadi Ali; [2015]
   Nyckelord :Ancillary data; land use land cover classification; supervised algorithms; GIS; Remote sensing; OBIA;

   Sammanfattning : Recently, there is a tremendous amount of high resolution imagery that wasn’t available years ago, mainly because of the advancement of the technology in capturing such images. Most of the very high resolution (VHR) imagery comes in three bands only the red, green and blue (RGB), whereas, the importance of using such imagery in remote sensing studies has been only considered lately, despite that, there are no enough studies examining the usefulness of these imagery in urban applications.

4. 13. 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.

5. 14. 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
