Estimating and measuring building height has become one of the significant factors in urban planning, legal and illegal construction inspection, urban disaster warning and assessing, as well as providing initial mapping data for creating three dimensional (3D) digital city models. In this paper we examine the feasibility of extracting building height information using computer vision algorithms with...
In this paper a method was demonstrated that GF-1 multi-spectral and MODIS multi-temporal NDVI data were integrated for forest land cover classification. The test site is located in the central of the Xiaoxing'anling region in Heilongjiang province where covered the area of one scene of GF-1 image. The random forests algorithm was adopted to select the best features automatically which contains spectral,...
