    • fromFeatureSource

      public static nz.org.riskscape.engine.types.Struct fromFeatureSource(org.geotools.api.data.SimpleFeatureSource fs, boolean includeFid)

      Infer a struct from the given FeatureSource TODO should we be passing in the CRS here? We have the potential to scrape a different CRS for our referenced value compared to the one that gets passed in to the spatial metadata

      Parameters:
      fs - a feature source to build a Struct from
      includeFid - if true, a special _fid member is added to the type which holds the value of SimpleFeature.getID().

      Infer a struct from the given SimpleFeatureType

      Parameters:
      type - a feature type to build a Struct from
      bounds - the geometric bounds if known (else null)
      includeFid - if true, a special _fid member is added to the type which holds the value of SimpleFeature.getID().
