Pressure analysis in the Natural National Park System of Colombia

Abstract

From the land cover monitoring that the National Natural Parks of Colombia has been developed since 2002 and that up to now develops the fifth period of analysis, currently the entity concentrates its efforts in analyzing areas under pressure, where natural cover has been lost due to anthropic causes. The purpose of the paper is to show how, with the use of remote sensors and geographic information systems, National Parks of Colombia as an institution facilitates the information on pressures behavior for decision making purposes. The detailed characterization of these areas allows us to know in more detail the phenomenon, the exercise of early warnings of transformation of natural coverages, allows to increase the capacity of reaction before the appearance of new pressures and the analysis of expansion vectors, the identification of areas with persistence and multitemporal analysis allow to see the behavior of pressures over time.
