Kart

Kart is a powerful tool designed for distributed version control of geospatial and tabular data, built upon the familiar Git system. It allows users to manage changes at a granular row and cell level, making it an essential resource for collaborative data projects. For those already proficient with Git, Kart's command-line interface and repository structure will feel intuitive and easy to adopt.

This tool integrates directly into existing GIS workflows, providing repository working copies as standard GIS databases and files. Users can edit data directly in common GIS software without requiring any special plugins. Kart supports a variety of data formats and types, including GeoPackage, PostGIS, Microsoft SQL Server, MySQL, vector features (points, lines, polygons), tabular data, raster and grid data, and LAS (terrestrial LiDAR) data.

Key features include branching and merging capabilities, allowing for independent local development and rapid synchronization of changes. Kart performs operations locally, offering significant performance advantages over server-based systems. It also provides spatial filtering for working with geographical subsets and a full change history for reviewing and reverting to any previous state of a dataset.
