Detailed intra-urban mapping through transferable OBIA rule sets using WorldView-2 very-high-resolution satellite images

摘要

A detailed knowledge of the types and coverage of intra-urban features is helpful for different applications, such as roof run-off approximation and urban micro-climate studies. Previous studies have applied object-based image analysis (OBIA) to explore the detailed urban characterization on a single image of satellite sensors with very-high-resolution. The automated and transferable detection of intra-urban features is challenging because of variations of the spatial and spectral characteristic
