file extension PRJ - ArcView Shapefile projections definition file
File extension PRJ description:
projection format; the coordinate system and projection information, a plain text file describing the projection using text format
The projection information contained in the .prj file is critical in order to understand the data contained in the .shp file correctly. Although it is technically optional, it is most often provided, as it is not necessarily possible to guess the projection of any given points. Some typical information contained in the .prj file is:
- Geographic coordinate system
- Datum
- Spheroid
- Prime meridian
- Map projection
- Units used
The ESRI Shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products. A shapefile commonly refers to a collection of files with .shp, .shx, .dbf, and other extensions on a common prefix name (e.g., "lakes.*"). The actual shapefile relates specifically to files with the ".shp" extension, however this file alone is incomplete for distribution, as the other supporting files are required.
Shapefiles spatially describe geometries: points, polylines, and polygons. These, for example, could represent water wells, rivers, and lakes, respectively. Each item may also have attributes, that describe the items, such as the name or temperature.
