LocationTech GeoGig

LocationTech GeoGig is a Distributed Version Control System (DVCS) specially designed to handle geospatial data efficiently. It takes inspiration from the source code versioning system Git, but has an approach suited to the spatial data it manages. GeoGig efficiently handles very large binary data, divided up into features with the opportunity to optimise spatial operations using a spatial index. This is in contrast to Git which handles large text data, divided up into lines.
