Changelog¶

0.1.1¶

Fix: checking a Shapefile/GPKG without the optional formats extra installed no longer also reports a spurious missing-crs warning alongside the real "install geomlint[formats]" error — the file was never read, so there was nothing to be missing a CRS.

Initial release.

Geometry validity & topology: self-intersections, collapsed rings, zero-area/zero-length shapes, duplicate consecutive vertices, ring winding order (RFC 7946), antimeridian crossings that weren't split, excessive/fake coordinate precision.
CRS sanity: unrecognized CRS, missing CRS (Shapefile/GPKG), coordinates out of WGS84 lon/lat range (e.g. UTM mislabeled as WGS84), mismatched CRS declarations across a batch of files.
Structural checks: duplicate feature ids within a file.
Input formats: GeoJSON natively (no GDAL, no system dependencies); Shapefile/GPKG behind the optional formats extra, via pyogrio (still no system GDAL).
Config: .geomlint.toml, or [tool.geomlint] in pyproject.toml, auto-discovered upward from the scan path (or --config). Tunes thresholds, disables specific checks, overrides severities, excludes path globs.
CLI: geomlint check <path...> — multiple files/directories in one run, table/JSON output, --fail-on severity gate for CI, --version.
Ecosystem: a composite GitHub Action (uses: DBishal13/geomlint@v0.1.0) and a pre-commit hook, both installing straight from this repo.
Not yet implemented, on purpose: positional/GPS-drift detection (multipath, sensor jumps) — see geomlint/checks/drift.py for the roadmap and why it's a harder statistical problem than a distance threshold.
