Everyone working with geospatial data eventually faces the problem of managing their information and assets as they change over time. Versioning of geospatial data has been an issue for any workflow that involves more than one individual. Questions like who changed what and when become hard to answer, and while versioning approaches have existed for a while, they are cumbersome to use and utilize old paradigms. GeoGit takes concepts and lessons learned from the open source programming world and applies them to management of geospatial information, allowing better and decentralized management of versioned data and enabling new and innovative workflows for collaboration. In this 2 hour workshop, we'll walk through core procedures in managing version history and inter-operating with preexisting spatial software tools.
