revrt.routing.base.CharacterizedLayer#

class CharacterizedLayer(name, layer, is_length_invariant=False, agg_method=None)[source]#

Bases: object

Encapsulate tracked routing layer metadata

Parameters:

  • name (str) – Identifier used when reporting layer-derived metrics.

  • layer (xarray.DataArray or dask.array.Array) – Data values sampled from the routing stack.

  • is_length_invariant (bool, default False) – Flag signaling cost values should ignore segment length. By default, False.

  • agg_method (str, optional) – Name of dask aggregation used when tracking statistics. By default, None.

Methods

compute(route, cell_size)

Compute layer metrics along a route
compute(route, cell_size)[source]#

Compute layer metrics along a route

Parameters:

  • route (sequence) – Ordered (row, col) indices describing the path.

  • cell_size (float) – Raster cell size in meters for distance calculations.

Returns:

dict – Mapping of metric names to aggregated layer values.
