DatumDrift

DatumDrift is a web app (with optional CLI) that continuously checks your geospatial datasets for “silent” changes: CRS/datum mismatches, geometry validity issues, topology breaks, attribute schema drift, and tile/coverage gaps. It plugs into common pipelines (S3/GCS/Azure Blob, PostGIS, GeoParquet) and runs scheduled validations, producing a simple scorecard plus actionable diffs (what changed, where, and likely cause). The goal is not fancy visualization—it’s preventing costly downstream failures in routing, geofencing, analytics, and map rendering. It also tracks lineage: which upstream source update caused the drift, and which downstream products are at risk. This is a traditional app with targeted AI assistance: AI helps classify anomalies, suggest fixes, and generate human-readable incident reports, but the core value is deterministic validation and monitoring.
