GIS data GIS data come in various formats, such as “shapefiles”, geodatabases (feature class), coverages, raster files GIS data come in various formats, such as “shapefiles”, geodatabases (feature class), coverages, raster files GIS vector files consist of the spatial entities (e.g., points, lines, polygons) AND the attributes of that entity (tabular) GIS vector files consist of the spatial entities (e.g., points, lines, polygons) AND the attributes of that entity (tabular) Raster files are arrays of “pixels” that contain discrete values Raster files are arrays of “pixels” that contain discrete values GIS data files are not simple files, and a special data management module is used to copy/move/paste files GIS data files are not simple files, and a special data management module is used to copy/move/paste files
