Generación automática de cartografía para edificaciones, utilizando fotografías digitales aéreas verticales de alta resolución espacial y nubes de puntos LiDAR

Abstract

The aim of this paper is to generate photogrammetric 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.
