Abstract | Quantitative and qualitative information about land-use and buildings are important for spatial planning decision processes. The presented study determines the suitability of multispectral information and stereo-derived heights of Pléiades tri-stereoscopic satellite imagery to identify building footprints. The study area is the Nyarugenge sector of the City of Kigali. A Pléiades satellite scene was used to process a digital surface model. An object-based image analysis provided the basic geometries and respective variables, which served as input features for a Support Vector Machine based classification. The comparison of the building footprints with ground reference information indicates a high accuracy. |
