Attribute records in the dBASE file must be in the same order as records in the main file. The one-to-one relationship between geometry and attributes is based on record number. dbf - dBASE Table file (mandatory) a constrained form of DBF that contains feature attributes with one record per feature.The index file (.shx) contains a 100-byte header followed by 8-byte, fixed-length records. In the index file, each record contains the offset of the corresponding main file record from the beginning of the main file. shp - Main file (mandatory) a direct access, variable-record-length file in which each record describes a shape with a list of its vertices.For example, a water GIS data set must have the minimum set of files: water.shp, water.shx, and water.dbf. There are three required files that, at a minimum, make up a shapefile. What File Extensions are Associated with a Shapefile?Īll shapefile files must have the same name but have different extensions.

zip file for transfer such as emailing as an attachment or via a web site download. Commonly, shapefiles are compressed in a. prj with the shapefile’s projection information. All three files must be present in the same directory for them to be viewable.

For example, shapefiles can be directly read by a number of GIS software programs such as ArcGIS and QGIS.ĭespite its name indicating a singular file, a shapefile is actually a collection of at least three basic files: .shp. Developed by Esri, shapefiles are now an open format and is a popular option for data transfer. Shapefiles store non-topological vector data along with related attribute data. See the Indexes toolset for more information about adding or removing an index in ArcGIS Pro.The shapefile format is now a common format for storing vector GIS data.

If you need to store or use these files encoded in different code pages, follow the instructions outlined in How To: Read and write shapefile and dBASE files encoded in various code pages. Shapefiles and dBASE files cannot store non-English characters by default.A shapefile cannot store topological information or relationships.NULL values are only supported on the Date field data type and are not supported for numeric or text field data types in a shapefile.Maximum field name length: 10 characters.Some field properties are read-only and are unavailable, such as Field Name.Ī shapefile has the following limitations:.Changing the layer properties of a field: visibility, read-only, or field alias.Here, edits are being made to a shapefile layer named Building. See An overview of fields for more information about the fields view.īelow is an example of some standard editing tasks you can do in the fields view. You can use the fields view to add or delete fields, view field properties, or modify layer properties for shapefiles. Working with shapefiles in the fields view Right-click the shapefile and select Add to Current Map to add the shapefile to the current map.Īlternatively, you can click Add Data on the Map tab on the ribbon and browse to the shapefile location. Browse to the location of the shapefile within the folder connection.
