Levantamiento de información geoespacial para la obtención de los linderos de predios rurales con metodología de bajo costo en un contexto de los métodos colaborativos propuestos en el catastro multipropósito

Abstract

The cadastre is essential for a country since it is an input for formulating public policies. Being the physical characterization of the properties is the basis of the land administration process, however, in the case of Colombia, this is outdated. Therefore, the present study aims to help in the collection of physical information on rural properties related to space and boundaries with low-cost equipment, for which smartphones are used to collect Rinex data and capture physical information taking elements of the Fit For Purpose methodology, additionally, post-processing is performed by Precise Point Positioning and differential relative method, to obtain the coordinates of two rural properties located in Viotá and Zipacón, for which it was previously necessary to compare the accuracy with two vertices of the geodetic network in Bogotá to determine according to the horizontal accuracy consigned in resolution 679 of 2022 and decree 148 of 2020 in which the use of this type of equipment is enabled. The main result of this study was the ability to use this equipment for geospatial data capture, fulfilling the horizontal accuracy of 5.2 meters in some cases, 13.01 and 21.6 meters in almost all cases. since the horizontal accuracy varies between 0.38 and 15.7 meters depending on the device, method, and post-processing software or service.
