| Popis: | In this article, the purpose is to monitor the Thomas van der Hammen forest reserve, the largest urban forest reserve in Colombia between 1977 and 2017. The analysis focuses on the change that occurs in land cover for the northern zone of the city of Bogota, especially to observe and identify the causes and the specific areas from which the urban expansion of the towns to the north of the city and two of its neighboring municipalities (Chia and Cota) begins to be generated. This study frames a special relevance due to the context of change of government in Bogota focused on a change in the land use plan and the possible urbanization of said reserve. To carry out this multitemporal analysis, various satellite images (Spot, RapidEye and Landsat) were classified in established periods of time and thus compare the information over time and quantify both the land cover and the area of ??change per period and accumulated. The study shows as the most impressive result the accelerated increase in construction land, which went from 500 hectares in 1977 to more than 5,100 hectares in 2017, which allows concluding the existence of a critical change that entails a direct impact on the structure. ecological reserve and where concepts such as the sustainable development of the Colombian capital are tested. |
