PostGIS extends the capabilities of the
PostgreSQL
relational database by adding support for storing, indexing, and querying geospatial data.
PostGIS features include:
Spatial Data Storage
: Store different types of spatial data such as points, lines, polygons, and multi-geometries, in both 2D and
3D
data.
Spatial Indexing
: Quickly
search
and retrieve spatial data based on its location.
Spatial Functions
: A wide range of spatial functions that allow you to filter and analyze spatial data, measuring
distances
and
areas
,
intersecting
geometries,
buffering
, and more.
Geometry Processing
: Tools for
processing
and
manipulating
geometry data, such as
simplification
,
conversion
, and generalization.
Raster Data Support
: Storage and processing of
raster data
, such as elevation data and weather data.
Geocoding and Reverse Geocoding
: Functions for
geocoding
and reverse geocoding.
Integration
: Access and work with PostGIS using third party tools such as
QGIS
,
GeoServer
,
MapServer
, ArcGIS, Tableau.
