CONSTRUÇÃO DO SISTEMA DE INFORMAÇÕESGEOGRÁFICAS DA MARGEM ESQUERDA DO CANALDO RIO GRANDE / SJN (SIG-MECR/SJN) COM BASE EMIMAGENS DIGITAIS DE PEQUENO FORMATO
This study presents a detailed mapping of the land uses along the left margin of theCanal do Rio Grande, municipality of São José do Norte. The mapping was conductedusing (a) interpretation of digital photographs (35 mm) acquired by airborne sensorADAR 1000 and (b) field surveys. A Geographical Information System (GIS),denominated SIG-MECRG/SJN, was created using the MegaGIS software. To build theGIS, it was necessary the application of geoprocessing techniques, and export andenhancement of digital photos. Additionally, data about the properties identified in thephotos were obtained through interviews with local residents. The high resolution of theaerial photos (0.5 m per pixel) combined with geoprocessing techniques allowed theidentification of the different targets in the urban area. The main targets identified in thearea are: houses, coastline, water flows, salt marshes, dunes, and man-made changes inthe landscape. The GIS allows searching of information according to specific needsfrom which data can be displayed in tabular or graphic formats.
