 ### Fixed
 
+- Make checks on max spatial resolution (1km) more lenient using math.isclose [\#30](https://github.com/mlcast-community/mlcast-dataset-validator/pull/30), @ladc
 - Detect Zarr v3 format from store files (`zarr.json`) instead of relying on `getattr(ds, "zarr_format", 2)` which always defaulted to v2, causing v3 stores to incorrectly fail the consolidated metadata check [\#27](https://github.com/mlcast-community/mlcast-dataset-validator/pull/27), @franchg
