ABOUT POSTGIS

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';

Docs for latest stable release

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.

POSTGIS 3.1.0

The PostGIS Team is pleased to release the release of PostGIS 3.1.0!

This version exposes the new features of GEOS 3.9 as well as numerous core
performance enhancements for spatial joins, large object access, text format
output and more.

Performance is a key feature of this release, with improvements to spatial
joins, text outputs, large object reads, vector tile output, and a host of
smaller tweaks.

The k-means clustering code has been enhanced to support weighting and higher
dimensional clusters.

Geometry generators to create hexagonal and square tilings have been added, for
simpler in-the-database summarization queries.

Finally, PostGIS exposes the latest enhancements in the GEOS geometry library
3.9 version. The new overlay engine (aka “OverlayNG”) provides more robust
handling of difficult input geometries, using a set of new noding strategies to
process geometry. For the end user, this should mean no more “topology
exceptions” when using the union, difference, intersection or symmetric
difference functions. PostGIS also exposes the new fixed precision overlay
capability via an additional grid-size parameter on ST_Intersection and the
other overlay functions.

TIPS


MOVE POSTGIS EXTENSION TO A DIFFERENT SCHEMA

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.

CASE STUDIES


HOWARD HUGHES MEDICAL INSTITUTE

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

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).
