Abstract
This paper describes a method to estimate FAR based on SRTM3 data and land use data. SRTM3 is DSM which includes height of objects on ground than DTM, so we can get general height information of buildings in city to estimate FAR. In the paper, a method is designed as the buildings' height information is gotten from SRTM3, building density and floor height are gotten from investigation varied by land use types. Then a model is built to calculate FAR used of SRTM3 and land use data. A case study in Shanghai central city is done to test the feasibility and accuracy of this method. Finally we analyze the factors affects the accuracy of estimation and discuss some improvement.
