Paul Ramsey has been working on this new feature to PostgreSQL for supporting
LIDAR data called Point Cloud and the project
is beginning to garner a lot of interest, particularly because Point Cloud support has been a hole in the PostGIS offering of support for some time now
and people have developed make shift ways of working with said data by storing them in geometry points.
Thanks to the gracious support of Coordinate Solutions for funding our build efforts, we now have Point Cloud extension builds
for PostgreSQL 9.2 and upcoming 9.3 releases (both 32-bit and 64-bit). The point cloud work is still a work in progress and as such
part of our work was to automate the builds so that whenever changes are made to the point cloud codebase, Winnie PostGIS build bot bakes a fresh set of binary builds. These builds can currently be found:
The above binaries just include the PostgreSQL pointcloud
extensions. To use you will also need PostGIS 2.0-2.2 already installed which you can get via Stackbuilder (or for the in-development, directly from Winnie's bakery
). They also do not include the loaders (which you can get as part of OSGEO4W installers
) and also do not include the optional GHT support.
Details of the new features and how it is used are on Paul's recent FOSS4GNA presentation LIDAR in PostgreSQL with PointCloud slides.
We plan to ship Point Cloud support starting in PostGIS 2.2 (as part of what we will dub the PostGIS bundle) since starting at PostGIS 2.1, the PostGIS windows stackbuilder package will contain, not just PostGIS, but also related PostGIS extensions: pgRouting and pagc address_standardizer (for additional address standardizing support with postgis_tiger_geocoder) extensions.
