Análisis comparativo de la información catastral vigente mediante la integración de marcas constructivas (building footprints): Caso de estudio unidades constructivas del departamento del Guaviare

Abstract

This document is based on the comparative analysis of the building units in the national cadastral base and secondary information sources of building footprints for the department of Guaviare. The main purpose is to obtain a detailed view of the spatial distribution and characteristics of buildings in urban and rural areas of each municipality. The methodology was developed in five main phases. In the first phase, cadastral data and construction marks were collected from various secondary sources. In the second phase, the data were cleaned and organized in databases in CSV format, divided by municipality and classified according to the use and score of the construction units. The third phase involved spatial analysis using ArcGIS Pro and Python in Jupyter Notebook, where the geographic data were integrated and visualized to identify the spatial distribution of the buildings. In the fourth phase, the cadastral base data were compared with the construction marks to identify discrepancies and validate the results. Finally, in the fifth phase, heat maps and other visualizations were generated to graphically represent the results. The results show a clear predominance of urban areas in all municipalities, especially in San José del Guaviare, which has a higher concentration of properties and construction units, as recorded in the cadastral base. It is important to note that the cadastral validity in the urban zone is from 2009, while the rural zone has not yet been formed. The number of construction marks exceeds the number of construction units registered, both in urban and rural areas, and the marks show a greater predominance of the number of constructions in the rural area.
