Geo-Information Technologies of Object Based Image Analysis (OBIA) for Urban Mapping [PDF]

open access: yes, 2019
Current work is aimed at the deriving of information from the remote sensed VHR data using a priori knowledge in the Object Based Image Analysis (OBIA) approach. OBIA technology is new and effective tool for urban mapping, as it enables dealing with raster images for detailed and precise cartography. Specific focus of this study is selected urban areas
