# Reproject datasets in place and open a pull request with the result.

# Runs in fix mode against the default branch on a schedule and on demand.
# Datasets carrying an unresolvable problem (missing CRS, no transformation
# path, a missing datum-shift grid, a rotated raster) are never rewritten on a
# guess, so a green run here means every change was safe to make.

# Copy to .github/workflows/crs-fix.yml in your repository.
