Actualización de la base de datos geográfica de fotografías aéreas para proyectos cartográficos del Instituto Geográfico Agustín Codazzi

Abstract

The Agustín Codazzi Geographic Institute (IGAC) is the entity in charge of producing the official map and basic cartography of Colombia; prepare the national cadastre of real property; carry out an inventory of soil characteristics; carry out geographic research to support territorial development; train and educate professionals in geographic information technologies and coordinate the Colombian Spatial Data Infrastructure (ICDE), located in the city of Bogotá with address Carrera 30 Nº 48-51 being the headquarters in the country (IGAC, 2018) For the elaboration of cartographic and geographic products such as: (basic cartography, thematic cartography, thematic maps of territorial entities, thematic atlases, cadastral maps, etc.) that allow the observation of details, limits, and connections throughout the territory, the Agustín Codazzi Geographic Institute applies the method of obtaining information by aerial photogrammetry. Method applied since 1922 to generate the first observations and aero triangulations of a region of the Magdalena river, since the application of this tool a physical record has been generated that documents flight number, place and department, number of photographs per flight, and their respective scale. Digital records are currently being generated to keep banks of information up-to-date, speeding up data modeling processes. Due to the advances in cartography in general, it becomes vitally important that the main institute that manages and regulates cartography at the national level begins to do what is necessary so that your information is organized and digitally as this determines in a way or another how modern it can be compared to the world, in addition to the importance of having all the country's geographic information just a click away from a modernizing entity.
