OSGeo4W

What is OSGeo4W?

OSGeo4W is a distribution of geospatial software built for Windows. The PDAL project provides Windows builds through this distribution.

How will we use OSGeo4W?

PDAL stands on the shoulders of giants. It uses GDAL, GEOS, and many other dependencies. Because of this, it is very challenging to build it yourself. We could easily burn an entire workshop learning the esoteric build miseries of PDAL and all of its dependencies. Fortunately, OSGeo4W provides us a fully-featured known configuration to run our examples and exercises without having to suffer so much.

Note

Not everyone uses Windows. Another alternative to get a known configuration is to go through the workshop using Install Docker as your platform. A previous edition of the workshop was provided as Docker, but it was found to be a bit too difficult to follow.

Installing OSGeo4W

  1. Copy the entire contents of your workshop USB key to a PDAL directory in your home directory (something like C:\Users\hobu\PDAL). We will refer to this location for the rest of the workshop materials.

  2. Download the OSGeo4W setup.exe http://download.osgeo.org/osgeo4w/osgeo4w-setup-x86_64.exe

    Warning

    PDAL is only available via the 64-bit verison of OSGeo4W. There is an older 32-bit version, but none of the workshop materials will work in that environment. You must be able to run 64-bit Windows applications to follow this workshop.

  3. Run the installer and choose the “Advanced Install” option.
