PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL.
SELECT superhero.name FROM city, superhero WHERE ST_Contains(city.geom, superhero.geom) AND city.name = 'Gotham';
In addition to basic location awareness, PostGIS offers many features rarely found in other competing spatial databases such as Oracle Locator/Spatial and SQL Server. Refer to PostGIS Feature List for more details.

The PostGIS development team is pleased to provide bug fix 2.5.2, 2.4.7, and 2.3.9 for the 2.5, 2.4, and 2.3 stable branches.
These are the first versions to be able to compile against Proj 6.0.0, You must upgrade to these if you are using Proj 6.
2.5.2 This release supports PostgreSQL 9.3-11 (will compile against PostgreSQL 12, but not pass tests. Use only for pg_upgrade. You are encouraged to use the PostGIS 3.0 unreleased branch with PostgreSQL 12 , which has features specifically designed to take advantage of features new in PostgreSQL 12).
2.4.7 This release supports PostgreSQL 9.3-10.
This release supports PostgreSQL 9.2-10.
View all closed tickets for 2.5.2, 2.4.7, 2.3.9.
After installing the binaries or after running pg_upgrade, make sure to do:
ALTER EXTENSION postgis UPDATE;
— if you use the other extensions packaged with postgis — make sure to upgrade those as well
ALTER EXTENSION postgis_sfcgal UPDATE; ALTER EXTENSION postgis_topology UPDATE; ALTER EXTENSION postgis_tiger_geocoder UPDATE;
If you use legacy.sql or legacy_minimal.sql, make sure to rerun the version packaged with these releases.
The PostGIS development team is pleased to provide bug fix 2.3.8 and 2.4.6 for the 2.3 and 2.4 stable branches.
The PostGIS development team is pleased to provide bug fix 2.2.8 for the 2.2 stable branch.
This is the End-Of-Life and final release for PostGIS 2.2 series.
We encourage you to upgrade to a newer minor PostGIS version. Refer to our Version compatibility and EOL Policy for details on versions you can upgrade to.
This release supports PostgreSQL 9.1-9.6.
The PostGIS development team is pleased to provide bug fix 2.5.1 for the 2.5 stable branch.
Although this release will work for PostgreSQL 9.4 thru PostgreSQL 11, to take full advantage of what PostGIS 2.5 offers, you should be running PostgreSQL 11 and GEOS 3.7.0.
WARNING: If compiling with PostgreSQL+JIT, LLVM >= 6 is required Supported PostgreSQL versions for this release are: PostgreSQL 9.4 - PostgreSQL 11 GEOS >= 3.5
As of PostGIS 2.3, the postgis extension was changed to no longer allow relocation. All function calls within the extension are now schema qualified.
While this change fixed some issues with database restore, it created the issue of if you installed PostGIS in a schema other than the one you wanted to it is not intuitive how to move it to a different schema. Luckily there is a way to do this.
For this exercise, I will install PostGIS in the default schema and then demonstrate how to move it into another schema location.
You can run these steps using psql or pgAdmin or any other PostgreSQL tool you want.
As a software engineer at the Howard Hughes Medical Institute, I work on a collaborative neuron reconstruction and analysis software called CATMAID 1 (screenshot: 3), which is used for neuroscience research. We use PostGIS to represent neurons in a 3D space.
Vanguard Appraisals is new to the GIS world. In fact, we aren’t really in the GIS world; we just kind of brush up against it. We do mass property appraisal for entire county and city jurisdictions, and we develop software to collect, price and maintain values. We also host assessment data online so that homeowners can search and find property information much simpler from the comfort of their own home. Our software and websites are used in 7 states (IA, IL, MN, MO, NE, ND, SD).
