SlopeClassificationLayer

_RANGES = [0, 5, 10, 25, 45]

fill_conf_and_schema(cfg: demcompare.internal_typing.ConfigType = None) → demcompare.internal_typing.ConfigType

Add default values to the dictionary if there are missing elements and define the configuration schema

Parameters:

cfg (ConfigType) – coregistration configuration

Return cfg:

coregistration configuration updated

Return type:

ConfigType

static check_ranges(cfg: dict) → None

Verify users configuration for ranges in slope classification :param cfg: slope configuration :type cfg: dict :return: None

_create_labelled_map()

Create the labelled map and save it if necessary :return: None

_create_slope_map_datasets(dem: xarray.Dataset)

Create slope map datasets

Parameters:

dem – input dem

Returns:

None

static _generate_classes(ranges) → collections.OrderedDict

Create classes from ranges

Parameters:

ranges (List) – ranges

Returns:

classes

Return type:

collections.OrderedDict

_classify_slope_by_ranges(slope_dataset: xarray.Dataset, support: str = 'ref')

Create the map for each slope using the input ranges (value interval is transformed into 1 value (interval minimum value))

Parameters:

• slope_dataset – slope dataset

• support (str) – support dem, ref or sec

Returns:

None
