Geotecnologias aplicadas ao uso e cobertura da terra no espaço rural de Teresina, Piauí

Abstract

The rural space presents particularities that are consequences of the relationship between different natural and human conditions, which is characterized by a set of functions and occupations. The diagnosis of a place, as well as the identification of its best planning methods, can be optimized when accurate data about its changes over an extended period is available, in order to measure the impact of the changes that took place there. Thus, the guiding question of this study aimed to understand how land use and occupation in rural Teresina behaved in the last 30 years. The general objective was to investigate the transformations in the rural space of Teresina –Piauí through changes in land use and the permanence of natural vegetation in the extensive territorial area; as specific objectives, we sought to: carry out a survey of the use and occupation of land in the rural area of Teresina; to model a geographic database containing information regarding the environmental resources contained in the rural area of Teresina; and characterize environmental resources in order to assess demands and possibilities. This study is of a qualiquantitative type as it presents itself of an analytical, descriptive and exploratory nature, having as a data collection instrument the use of several technical instruments to achieve the objectives such as: bibliographic review; survey and analysis of georeferenced data using QGIS software; spatial analysis using land use and land cover classifications generated by mapbiomas and the construction and elaboration of thematic maps. The results presented in this report were structured in an Atlas of Rural de Teresina to be later made available to society
