Automated mapping of buildings through classification of DSM-based ortho-images and cartographic enhancement
Autor: Joachim Höhle
Publikováno v: International Journal of Applied Earth Observations and Geoinformation, Vol 95, Iss , Pp 102237- (2021)
Urban areas are changing rapidly. In order to document the urban realities in topographic databases and geographic information systems efficient methods are required. Vector data of buildings are of special importance. A methodology for an automated

Generating Topographic Map Data from Classification Results
Autor: Joachim Höhle
Publikováno v: Remote Sensing, Vol 9, Iss 3, p 224 (2017)
The use of classification results as topographic map data requires cartographic enhancement and checking of the geometric accuracy. Urban areas are of special interest. The conversion of the classification result into topographic map data of high the
