varunayan.processing.data_filter module#

varunayan.processing.data_filter.filter_netcdf_by_shapefile(ds: Dataset, geojson_data: Dict[str, Any]) → DataFrame[source]#

Filter a NetCDF dataset to only include grid points that fall within the GeoJSON polygon(s). Internally handles multi-feature GeoJSONs by matching points to each feature individually, then taking the union of all matched points.

Parameters:

  • ds – xarray Dataset

  • geojson_data – Loaded GeoJSON (as dict or GeoDataFrame)

Returns:

A pandas DataFrame with filtered points.

varunayan.processing.data_filter.get_unique_coordinates_in_polygon(ds: Dataset, geojson_data: Dict[str, Any]) → DataFrame[source]#

Alternative helper function that returns just the unique lat/lon pairs inside the polygon. This can be useful for other operations or caching coordinate filtering results.

varunayan.processing.data_filter.set_v_data_fil(verbosity: int)[source]#
