PostGIS 1.3.2

PostGIS by Paul Ramsey is a free and open-source software application that adds support for geographic objects to the PostgreSQL object-relational database. It allows users to store and query spatial data using SQL, making it a powerful tool for location-based applications and geographic information systems.

With PostGIS, users can create and manipulate spatial data such as points, lines, and polygons. The application provides a wide range of functions for spatial analysis, including distance calculations, area calculations, and geometric operations.

PostGIS is widely used in a variety of industries, including urban planning, environmental science, and transportation. Its ability to handle complex spatial queries makes it a valuable tool for organizations dealing with large volumes of geographic data.

One of the key features of PostGIS is its compatibility with the OGC (Open Geospatial Consortium) standards. This ensures that spatial data stored in PostGIS can be easily shared and accessed by other GIS applications that support the same standards.

PostGIS also integrates seamlessly with other open-source geospatial tools, such as QGIS and GeoServer, allowing users to build comprehensive GIS workflows using a combination of different applications.

PostGIS by Paul Ramsey is a versatile and powerful tool for anyone working with spatial data in a PostgreSQL environment. Its ease of use, extensive functionality, and compatibility with industry standards make it a top choice for GIS professionals around the world.
