jiayuasu opened a new issue, #3115: URL: https://github.com/apache/sedona/issues/3115
### Description Add a read-only Spark data source that exposes NetCDF file metadata (dimensions, variables, attributes, and spatial extent) without reading data arrays, the NetCDF counterpart to the `geotiff.metadata` source added in #2846. This is the NetCDF half of the original gdalinfo-like data source request (#2824), which was closed when the GeoTIFF source merged. ### Proposed behavior - New `netcdf.metadata` format returning one row per file. - NetCDF-native schema: `dimensions[]`, `variables[]` (with dims, shape, CF attributes, `_FillValue`, `isCoordinate`), `globalAttributes`, and nullable `geoTransform`/`cornerCoordinates`. - CRS/SRID resolved from the CF `grid_mapping` variable. - Metadata read from cloud storage via range requests (no full-file download); classic NetCDF and NetCDF-4/HDF5 supported. ### Related - #2824 (original gdalinfo-like data source request) - #2846 (`geotiff.metadata`) -- This is an automated message from the Apache Git Service.
