PostGIS adds GIS spatial types and support to PostgreSQL. It provides new types to PostgreSQL geometry, geography, raster, and topogeometry and SQL/ MM

pgWriteRast: Write raster to PostGIS database table. rpostgis: R interface to a PostGIS database. Browse all Installing PostGIS¶ PostGIS adds geographic object support to PostgreSQL, turning it into a spatial database. GEOS, PROJ.4 and GDAL should be installed prior to building PostGIS.

PostGIS gives you a choice of two different ways to store geospatial data: Geometry , where it assumes all of your data lives on a Cartesian plane (like a map projection ); Geography , where it assumes that your data is made up of points on the earth’s surface, as specified by latitudes and longitudes.

PPyGIS is an extension for psycopg2. PPyGIS adds support for PostGIS geometry objects by translating them between PostGIS EWKB representation and python objects.

This method implements the OpenGIS Simple Features Implementation Specification for SQL 1.1. This method supports Circular Strings and Curves. PostGIS stores a table’s spatial information in geometry columns. Usually these columns have the word “geom” floating around in their name.

pgpointcloud 1.2.0 (only the 64-bit packages have this) for querying LIDAR point cloud and in/out functions to convert to PostGIS geometry; The simplest way to get PostGIS on Windows for the EnterpriseDb Windows PostgreSQL distribution is using the StackBuilder. Refer to An Almost Idiot’s Guide Installing PostGIS on Windows 1. GEOMETRY and GEOGRAPHY are different PostgreSQL TYPES; exposed as higher level (SQL), user-defined composite types to the psql environment, but implemented as lower level (C) base types. These base types are defined on the C level with e.g. their own typemod constraints, TOAST support, data I/O functions, operator classes and casting behaviour.

PostGIS is a product that spatially enables PostgreSQL databases. PostGIS follows the OGC Simple Features specification for an SQL. It uses the OGC well-known binary (WKB) and well-known text (WKT) representations of geometry. PostGIS has two spatial type options: geometry and geography.

Views that use geometry functions that output other geometries will need to be cast to typmod geometries for these view geometry columns to be registered correctly in geometry_columns. Refer to Section 4.1.3.4, “Manually Registering Geometry Columns”.

PostGIS Function Support Matrix 13.11. New, Enhanced or changed PostGIS Functions 13.11.1. Within the database, geometries are stored on disk in a format only used by the PostGIS program. In order for external programs to insert and retrieve useful geometries, they need to be converted into a format that other applications can understand. Fortunately, PostGIS supports emitting and consuming geometries in a large number of formats: geometry is a fundamental PostGIS spatial data type used to represent a feature in planar (Euclidean) coordinate systems.
