nsidc.metgen.readers.netcdf_reader

Interface functions that read various metadata attribute values from source science data files.

Functions

bounding_rectangle_from_attrs(netcdf)	Extract bounding rectangle from lat/lon geospatial attributes.
crs_transformer(wkt)
distill_points(xdata, ydata, pad)
extract_metadata(netcdf_path, ...)	Read the content at netcdf_path and return a structure with temporal coverage information, spatial coverage information, file size, and production datetime.
find_coordinate_data_by_standard_name(...)
find_grid_mapping_var(netcdf)
find_grid_wkt(grid_var)
log_and_raise_error(err)
pixel_padding(grid_var, configuration)
points_from_coordinate_variables(netcdf, ...)	Extract bounding rectangle using coordinate transformation from projection coordinates.
points_from_geospatial_bounds(netcdf)	Extract polygon vertices from geospatial_bounds WKT POLYGON attribute, transforming to EPSG:4326 if necessary.
spatial_values(netcdf, configuration, gsr)	Return an array of dicts, each dict representing one lat/lon pair like so:
thinned_perimeter(rawx, rawy[, pad])	Generate the thinned perimeter of a grid.
time_coverage_end(netcdf, configuration, ...)	Use time_coverage_end attribute if it exists, otherwise use a duration value from the ini file to calculate the time_coverage_end.
time_coverage_start(netcdf_filename, netcdf, ...)
time_range(netcdf_filename, netcdf, ...)	Return an array of datetime strings
