HDFEOSShapefileMask

class GeoEDF.processor.HDFEOSShapefileMask

This processor aggregates the data values from a HDF file for a given shapefile containing polygons. One or more subdatasets from the HDF file can be aggregated. The result is a new shapefile with the same features as the original with new fields added for each subdataset’s aggregate value for a polygon feature.

hdffile(str, required)

This is the input HDF file. The attribute can be a local file path or a workflow stage reference.

shapefile(str, required)

This needs to be a local file path to an ESRI .shp shapefile.

datasets(list, required)

This is a list of one or more names of subdatasets that need to be aggregated.

Notes

1. This processor supports both HDF4 and HDF5, but assumes that the files are in the HDF-EOS format.
2. All processing occurs in the latitude-longitude space by reprojecting the shapefile to WGS84 and extracting the lat-lon for each grid cell in the HDF file. Extraction of cell lat-lon pairs for HDF4 files relies on the eos2dump utility.
