Resumo: Medium-resolution satellite images have been widely used for the identification and quantification of irrigated areas by center pivot. These areas, which present predominantly circular forms, can be easily identified by visual analyses of these images. In addition to identifying and quantifying areas irrigated by center pivot, other information that is associated to these areas is fundamental for producing cadastral maps. The goal of this work was to generate cadastral mapping of areas irrigated by center pivots in the State of Minas Gerais, Brazil, with the purpose of supplying information on irrigated agriculture. Using the satellite CBERS2B/CCD, images were used to identify and quantify irrigated areas and then associate these areas with a database containing information about: irrigated area, perimeter, municipality, path row, basin in which the pivot is located, and the date of image acquisition.3,781 center pivots systems were identified. The smallest area irrigated was 4.6 hectares and the largest one was 192.6 hectares. The total estimated value of irrigated area was 254,875 hectares. The largest number of center pivots appeared in the municipalities of Unaí and Paracatu, with 495 and 459 systems, respectively. Cadastral mapping is a very useful tool to assist and enhance information on irrigated agriculture in the State of Minas Gerais.

Essas áreas, por apresentarem formas predominantemente circulares, podem ser facilmente identificadas por meio de análises visuais dessas imagens. Além da identificação e quantificação das áreas irrigadas por pivô, a adição de outras informações complementares a estas áreas é fundamental para gerar mapas cadastrais. O objetivo deste trabalho foi gerar um mapeamento cadastral das áreas irrigadas por pivôs centrais no Estado de Minas Gerais com a finalidade de suprir a carência de informações relativas à agricultura irrigada. Utilizando imagens do satélite CBERS2B/CCD, foi feita a identificação e quantificação das áreas irrigadas e, em seguida, foi associado um banco de dados contendo informações sobre: a área irrigada, o perímetro, o município, a órbita-ponto, a bacia hidrográfica na qual o pivô está localizado e a data de aquisição da imagem. Foram identificados 3.781 sistemas de pivôs centrais. A menor área irrigada foi de 4,6 hectares, e a maior foi de 192,6 hectares. O valor total estimado de área irrigada foi de 254.875 hectares. O maior número de pivôs centrais apareceu nos municípios de Unaí e Paracatu, que apresentaram 495 e 459 sistemas, respectivamente. O mapeamento cadastral é uma ferramenta muito útil para auxiliar e aumentar a informação sobre a agricultura irrigada no Estado de Minas Gerais.Associação Brasileira de Engenharia Agrícola2017-02-20T17:30:38Z2017-02-20T17:30:38Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFERREIRA, E. et al.
