Mantenimiento y actualización de la GDB de aerofotografías análogas y digitales tomadas a lo largo de la historia por el IGAC con su respectiva georreferenciación y control de calidad

Abstract

The Instituto Geográfico Agustín Codazzi – cartographic agency of Colombia - has made throughout history the capture of analog and digital aerial photographs of the national territory, which have been compiled in Geodatabases (GDB). This Degree Work exposes the procedures for the Maintenance and Updating of these databases, which include raster information and a set of vector data which, after checking their georeferencing and quality control must been shown coherent with each other; otherwise, existing anomalies are identified and reported.
