Description

PostGIS is an open-source software library for geographic information systems (GIS) that extends the PostgreSQL object-relational database management system (ORDBMS). It adds support for geographic objects allowing location queries to be run in SQL. PostGIS offers the ability to store, query, and manipulate spatial data. It allows users to store, query, and analyze spatial data in a database environment and to render them with a variety of mapping and visualization tools. PostGIS supports a wide variety of vector formats, raster formats, and data manipulations. It provides a wide range of spatial functions and operators to help users find, measure, and analyze spatial information. PostGIS also allows users to create and store spatial data in PostgreSQL and to access spatial data from other sources, such as web services. PostGIS is a powerful tool for creating dynamic, interactive, and location-based applications. It enables users to create custom maps, analyze data, and integrate GIS data into existing applications and websites. PostGIS is an ideal solution for creating location-based applications, such as travel and navigation applications, online mapping services, and real estate applications.
