Item Análisis del cambio de la cobertura del suelo debido a la ampliación de la vía 3G Briceño – Tunja – Sogamoso(Universidad Santiago de Cali, 2024-08-10) González Sánchez, Daniel Fernando; Arias Molina, Johannes; Escalante Caicedo, Ana BelyRoad structures play a fundamental role since they are responsible for connecting different areas of the country. Therefore, their demand has increased in Colombia in recent years, allowing the population to move more efficiently and transport raw materials to places that were difficult in the past. One of the most important roads is the Briceño – Tunja – Sogamoso (BTS) road corridor as it is considered essential for the economic and social progress of the region, having a significant impact on local ecosystems, surface and land use. This study sought to identify and quantify changes in land use before and after the expansion of the BTS road using Geographic Information Systems (GIS) tools. To achieve this objective, a series of steps were carried out, such as extracting the Landsat 5 and 8 satellite images through which the Normalized Vegetation Index (NDVI) was calculated in addition to classifying the various land covers in the area. . study. The results obtained through coverage zoning, quantification of areas of influence and analysis of environmental and anthropic conditions indicate that the expansion of the agricultural frontier has had a negative impact on the forests within the area of influence in the region. Likewise, using the National Geostatistical Framework, an increase will be observed in the population centers within the area surrounding the BTS road corridor and also in the population of the municipalities in the area of influence of the project. This territorial development was reflected in the economic progress of the Cundiboyacense region where the agricultural, construction and provision of public services sectors had an increase in their share of the GDP of the department of Boyacá, while in Cundinamarca, the sectors of construction, provision of public services and commerce, repair, transportation and accommodation had an increase in their participation in the GDP of that department.
