RELATIONSHIP BETWEEN VEGETATION INDICES AND ALTIMETRY IN TRIUNFO-PE, BRAZIL

To make an analysis of the natural conditions of a particular area it is necessary to take into consideration the various variables that it has influence. The most used in these studies are the temperature and precipitation, however, this paper proposes a more comprehensive analysis and inserts the altitude as being one of those important variables. Today it is possible to study various aspects of a natural area through the techniques of Remote Sensing and Geoprocessing. This technique, combined with a good data base allows us to accurately plot the physiognomy of the field of study. Events such as deforestation, expansion of urbanization, land use, and also their composition, are features that can, for example, be the object of study through the geotechnologies. With this in mind, the present work aims to make an analysis of the natural aspects of the municipality of Triunfo, located in the Vale do Pajeu, microregion of Pernambuco. On which note that the altitude is a relevant factor in the physical characteristics of the region, due to the clear increase in the density of vegetation in virtue of the largest dimensions altimetric data.
