- Abstract
Land use and occupation studies are important parameters for the management of agricultural and forestry operations, such as Uruçuí, located in the southwest region of Piauí, an important municipality in the Brazilian agribusiness. In this way, the objective of this work is to characterize, through GIS (Geographic Information System) mapping, the vegetation cover and land use in the municipality of Uruçuí - Piauí. Landsat TM 8 satellite images were used for 2016 in order to evaluate the current configuration of the area. An unsupervised classification was performed, divided into five classes, and processed by the Maximum Likelihood Classification command of the ArcGIS 10.3 software. Based on the mapping, we observed 260.7 km² of the class Ripária or Dense Forest, 1,807.13 km² of Cerrado Denso, 2,788.71 km² of Cerrado Typical, 1,785.9 km² of Cerrado Field or Rala Vegetation, 1,069.37 Km² of Agricultural Field and an area corresponding to 704.67 km² of Exposed Ground. From the results, high land use and occupation in the municipality of Uruçuí (PI) was verified, henceforth potential areas for advancement, making necessary interventions of the responsible environmental agencies for the promotion of public policies for the conservation and preservation, management and Rational use of the soil.
