The US Census Bureau maintains a specific type of shapefile referred to as TIGER or TIGER/Line (Topologically Integrated Geographic Encoding and Referencing system). Coverages cannot be edited in ArcGIS 9.x or later versions of ESRI’s software package. File names cannot be longer than thirteen characters, cannot contain spaces, cannot start with a number, and must be completely in lowercase. Attribute data are stored as multiple files in a separate directory labeled “Info.” Due to its creation in an MS-DOS environment, these files maintain strict naming conventions. This georelational file format supports multiple features types (e.g., points, lines, polygons, annotations) while also storing the topological information associated with those features. The earliest vector format file for use in GIS software packages, which is still in use today, is the ArcInfo coverage. Geocoding index for read-write shapefiles with ODB formatĪttribute index used in ArcGIS 8 and laterĬode page specifications for identifying character encoding Geocoding index for read-write shapefiles Table 5.1 Shapefile File Types File Extensionįeature attribute information in dBASE IV formatĪttribute information for active fields in the table The more recent GIS software packages have relaxed this requirement and will accept longer filename prefixes. According to this convention, the filename prefix can contain up to eight characters, and the filename suffix contains three characters. As a general rule, the names for each file should conform to the MS-DOS 8.3 convention when using older versions of GIS software packages. Among those listed, only the SHP, SHX, and DBF file formats are mandatory to create a functioning shapefile, while all others are conditionally required. Table 5.1 lists and describes the different file formats associated with the shapefile. Shapefiles are supported by almost all commercial and open-source GIS software.ĭespite being called a “shapefile,” this format is actually a compilation of many different files. Supported data types are limited to floating point, integer, date, and text. Field names within the attribute table are limited to ten characters, and each shapefile can represent only point, line, or polygon feature sets. Shapefiles are incapable of storing null values, as well as annotations or network features. Shapefiles, developed by ESRI in the early 1990s for use with the dBASE III database management software package in ArcView 2, are simple, nontopological files developed to store the geometric location and attribute information of geographic features. The most common vector file format is the shapefile.

When it's supported as a raster type, it needs to be added to a mosaic dataset to be handled correctly in the application. There are three ways in which your raster and image data may be supported in ArcGIS: as a raster dataset that is derived from a storage format, as a raster product that is derived from specific metadata files, or as a raster type.
