4. Urban classification by pixel and object-based approaches for very high resolution imagery
University essay from Högskolan i Gävle/Samhällsbyggnad, GISAbstract : 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.
