Automatic extraction of wind erosion obstacles by integration of GIS data, DSM and stereo images
Abstract:Integrating multiple data sources is a very important strategy to obtain relevant solutions in geo‐scientific analysis. This paper mainly deals with the integration of Geographical Information System (GIS) data, stereo aerial imagery and a Digital Surface Model (DSM) to extract wind erosion obstacles (namely tree rows and hedges) in open landscapes. Different approaches, such as image segmentation, edge extraction, linking, grouping and 3‐dimensional verification with the DSM, are combined to extract the objects of interest. Experiments show that most wind erosion obstacles can be successfully extracted by the developed system.
