PCM Runout Distance Error

Using min. area bounding boxes to calculate predicted length, it measures the relative error, relative difference and error.

errMinBboxLength(obs_poly, pred_raster, dem)

Arguments

obs_poly	The observed/mapped runout track as a SpatialPolygonsDataFrame
pred_raster	A RasterLayer object predicting runout
dem	A DEM as a RasterLayer object

Value

A list of error measures
