v5.0 Table 10c-11 Structure fo Feature Instance Groups (optional)
From 4.2.1.1.1.12, The attribute extent has the value class CV_GridEnvelope that shall contain the extent of the spatial domain of the coverage. It uses the value class CV_GridEnvelope which provides the grid coordinate values for the diametrically opposed corners of the grid. The default is that this value is derived from the bounding box for the data set or tile in a multi tile data set

- initialize_properties(recursively_create_children=False, overwrite=True)
Calls the create function for all the properties of the class. Default values will be created for each attribute that is expected to be contained in this object.
For example, say a class has simple attributes of ESPG code (int) and locatilty (str) and then a class made from S1xxObject called “extents” which has east and west inside it.
Calling initialize_properties(recursively_create_children=False) would result in EPSG=0, locality=”” and an instance of the “extents” class but NO value (nothing would be written to HDF5) for east, west.
Calling initialize_properties(recursively_create_children=True) would result in EPSG=0, locality=”” and an instance of the “extents” class but with east=0.0 and wesst=0.0 as well.
Calling initialize_properties(recursively_create_children=True, overwrite=False) with an esiting dataset, say locality=”test” would result in EPSG=0 being made, locality=”test” being retained and an instance of the “extents” class with east=0.0 and wesst=0.0 as well.
- Parameters:
recursively_create_children – True = Create children for any child data that would have other children False = Only create data for immediate children of this instance
overwrite – True = Overwrite existing data with new default data False = Keep existing data if it exists but create new data otherwise
