Empleo de S.I.G. en la zonificación de amenaza por Incendios de la cobertura vegetal en Cuítiva-Boyacá escala 1:25000

Abstract

The document contains the technical support of the vegetation cover fire threat zoning in 1:25.000 scale for the municipality of Cuítiva, Boyacá, covering a total extension of 44.29 Km2, of which 36.39 Km2 are distributed in eleven rural territorial division centers, a village, an urban center and 7.9 Km2 occupied by the Lake Tota water body. For this purpose, the Protocol for the realization of zoning maps of fire risk of vegetation cover, proposed by the Institute of Hydrology Meteorology and Environmental Studies (IDEAM), 2011, is used as a reference. The methodology involves the evaluation of five components: vegetation susceptibility to fire, relief factor, accessibility, historical factor and climatic factor. To this last one, three additional variables are incorporated: suntrap – shade, solar brightness and prevailing winds direction; implementing a geographic information system (GIS) that allows the storage, analytical processing and visualization of results at the spatial level.
