Geospatial Data
Reproducible spatial workflows for GIS teams, data engineers, and open-source maintainers. From delta tracking and branching strategies to conflict resolution and CI/CD for spatial data.
Modern GIS workflows demand the same engineering rigor as software development — yet spatial datasets introduce unique constraints that traditional version control systems struggle to handle. Multi-gigabyte raster mosaics, topology-sensitive vector networks, and complex coordinate reference system transformations make naive Git usage impractical at scale. This site provides production-grade patterns, tool configurations, and code examples for teams managing spatial data with DVC, GeoGit, and Git LFS.
Whether you are a GIS analyst implementing your first branching workflow, a data engineer automating spatial CI/CD pipelines, or an open-source maintainer resolving geometry conflicts in pull requests — you will find practical, implementation-ready guidance here. Every guide covers the underlying theory, common failure modes, and concrete Python and shell code you can adapt directly to your stack.
Coverage spans three interconnected domains: the fundamentals of spatial versioning architecture (delta tracking, pointer synchronisation, security), branching and merge strategies tailored for GeoPackage, Shapefile, and raster workflows, and conflict resolution & team synchronization — from automated patching to attribute reconciliation with Pandas and GeoPandas.
Fundamentals & Architecture
Core architectural patterns for spatial version control — storage layers, metadata coupling, pointer files, delta compression, and security boundaries.
Branching & Merge Strategies
Branching models for GIS teams, feature workflows for GeoPackage projects, automated conflict detection, spatial diff algorithms, and release tagging.
Conflict Resolution & Team Sync
Geometry overlap resolution, attribute reconciliation with Pandas, automated patching for minor shifts, and manual review triggers for critical spatial edits.
