Abstract:
The level o f urban land intens ive use is related to how to plan the urban land . LiDAR ( Light Detection And Rang ing ) data are a prim ary data source for dig ita l terrain m odel ( DTM ) gene ration and 3D c ity m ode ls. This paper presents a three-stage fram ew ork fo r a robust autom atic urban land intensive use assessm ent based on raw LIDAR data. In the first stag e the raw da ta are classified to vege tations, build ings and so on. In the second stage, 100× 100 m eters ce ll are created, 3d house-land index and veg etation-land index a re com puted and stored in each ce l.l In the th ird stage, create them atic map of urban land intensive use assessm en t. Fina lly, one LiDAR datasets g athered over the c ity o f Xuzhou, Jiangsu prov ince ( Ch ina) w ith Optech airborne laser scann ing system s, are show n to illustrate the e ffectiv eness of the proposed approach.
