Análise multitemporal do uso e ocupação do solo do câmpus da UTFPR-DV utilizando imagens de satélite

Abstract

The land use mapping in a region of great importance by the need to understand the organization of space and its changes since the environment undergoes changes caused by natural processes and, mainly by human activities. Geotechnologies such as surveying, remote sensing, cartography, associated through the geoprocessing, in aid of land use mapping, represent an important tool for planning and administration of the occupation of the physical environment, allowing the evaluation and monitoring of the same. In this sense, the present study aimed to carry out a multi-temporal analysis on the use of mapping and soil occupation UTFPR-DV Campus in the years 2008, 2012 and 2014, intending a comparison and discussion of the percentage of each type of use determined. The study was conducted at the Campus UTFPR in the city of Dois Vizihos/PR. The images of 2008 and 2014 were obtained through Google Earth ® and the image 2012 had been obtained by WorldView-II optical sensor with spatial resolution of 0.5 m. The images were processed and segmented by SPRING software (version 5.2.7) and subsequently exported to another GIS environment for editing and quantification of land use classes. As a result of the work, there was obtained a current theme use mapping and campus land occupation UTFPR-DV, along with the quantification of certain types of use and the comparison between the maps operated in the three years under consideration and, consequently, the discussion of the data obtained.
