BARRAGAN ZAQUE, William; MARTINEZ RIVILLAS, Alexander  e  GARZON CARRENO, Pablo Emilio. LiDAR The Generation of Automatic Mapping for Buildings, Using High Spatial Resolution Digital Vertical Aerial Photography and LiDAR Point Clouds. rev.ing. [online]. 2015, n.42, pp.30-38.

The aim of this paper is to generate photogrammetrie products and to automatically map buildings in the area of interest in vector format. The research was conducted Bogotá using high resolution digital vertical aerial photographs and point clouds obtained using LIDAR technology. Image segmentation was also used, alongside radiometric and geometric digital processes. The process took into account aspects including building height, segmentation algorithms, and spectral band combination. The results had an effectiveness of 97.2 % validated through ground-truthing

Palavras-chave : Mapping; automatic extraction; photogrammetry; aerial photography; image segmentation.
