LANDSCAPE METRICS OF THE ENVIRONMENTAL PROTECTION AREA OF CONCEIÇÃO DA BARRA, NORTH COAST OF ESPÍRITO SANTO, FROM THE SURVEY OF LAND USE AND LAND COVER FOR THE 1970 AND 2012/2014

Abstract

This article deals with the metrics resulting from data generated from the survey of land use and land cover in 1970 and 2012/2014, in the Conceição da Barra Environmental Protection Area, located on the north coast of the Espírito Santo state. The research was supported by the theoretical-methodological framework of Landscape Ecology, recommended by biogeographer Carl Troll. From a methodological point of view, aerial photographs were vectorized for the year 1970 and orthophotomosaics for the years 2012/2014 of the APA area of Conceição da Barra using the software ArcGis™ version 10.3., whose license is from the Laboratory of the Cartography and Geotechnologies of the Department of Geography of the Federal University of Espírito Santo. Raster files were subsequently generated using land use and coverage for the two time frames. From the land use and land cover classes, landscape metrics were generated using the free Fragstats software, which are represented through graphs and maps. The data generated from the mappings were used to understand the dynamics and current structure of the landscape, as well as to define the APA matrix in both time frames. As a result, the Environmental Resources matrix for 1970 and 2012/2014 was defined.
