Welcome to the GeoGig workshop!
This workshop will introduce attendees to GeoGig, a distributed version control system for geospatial data. We will start with a discussion of distributed version control as applied to the specific case of geospatial data, followed by a hands-on session with the GeoGig command-line interface, and finally the graphical GeoGig interface in QGIS. Attendees will learn how GeoGig can be a key tool in a workflow when managing geospatial data.
The workshop is geared toward those with no prior GeoGig experience, but familiarity with basic GIS concepts is suggested. It will also be useful to have familiarity with the desktop GIS client QGIS, along with Git, the distributed version control system, but neither of these are required.
Prerequisites and software setup¶
In order to perform this workshop, you will need the following software installed on your system:
In addition, we will be using a plugin for QGIS that comes with a copy of GeoGig bundled inside. This download may be used on all operating systems:
This workshop uses the following bikes dataset:
