Zonal Threshold
Assigns corridor thresholds to the input lines based on their surrounding canopy density.
Python Interface
Method
Zonal Threshold provide Python method for calling directly:
def zonalThreshold(in_line, corridor_thresh, canopy_raster, canopy_search_radius
min_value, max_value, out_line)
Parameters
Input Lines: Input polyline shapefile for which each feature will be assigned an unique corridor threshold.
corridor_thresh: Name of the field (within the input lines) that indicates the corridor thresholds.
canopy_raster: Input canopy raster used to estimate canopy density.
canopy_search_radius: Search radius around line features where zonal statistics are calculated.
min_value: Minimum value for corridor threshold.
max_value: Maximum value for corridor threshold.
out_line: Output features that will be created.
