   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Melanie Stammler; [2020]
   Keywords : sand dunes; geomorphological mapping; object-based image analysis; landscape development; sanddyner; geomorfologisk kartläggning; geografisk objektbaserad bildanalys; landskapsutveckling;

   Abstract : Climate change has repeatedly been framed as the defining issue of the Anthropocene and with the Arctic changing at unpreceded speed need is high for a profound understanding of the Northern Swedish landscape. Northern Swedish aeolian sand dunes have been impacted by climatic changes throughout time. READ MORE

3. 2. Investigating the potential of object-based image analysis to identify tree avenues in high resolution aerial imagery and lidar data : a literature review

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Greta Moreen Wistrand; [2016]
   Keywords : eCognition; remote sensing; geographic object-based image analysis; GE OBIA; lidar; tree avenues; landscape elements; monitoring; physical geography and ecosystem science; Earth and Environmental Sciences;

   Abstract : The aim of this study was to investigate the potential of geographic object-based image analysis (GEOBIA) for the identification and monitoring of tree avenues with the help of aerial imagery and lidar data. For this, a literature review into three topics was conducted: First, scientific literature in form of journal articles, text books, and reports were used to highlight key features of GEOBIA.

4. 3. Automating Geographic Object-Based Image Analysis and Assessing the Methods Transferability : A Case Study Using High Resolution Geografiska SverigedataTM Orthophotos

   University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

   Author : Isak Hast; Asmelash Mehari; [2016]
   Keywords : automatic training area selection; scale parameterisation; multiresolution segmentation; classification rule-sets; positional accuracy;

   Abstract : Geographic object-based image analysis (GEOBIA) is an innovative image classification technique that treats spatial features in an image as objects, rather than as pixels; thus resembling closer to that of human perception of the geographic space. However, the process of a GEOBIA application allows for multiple interpretations. READ MORE

5. 4. Urban classification by pixel and object-based approaches for very high resolution imagery

   University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

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

   Abstract : 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.
