In KevinShook/WDPMr: Post-processing for the WDPM and PCM models

Removes roads from a DEM

Description

Removes roads from a DEM

Usage

remove_roads(DEM_file, road_shapefile, basin_shapefile)

Arguments

DEM_file	Required. ArcGIS .asc file.
road_shapefile	Required. Shapefile of roads buffered to road widths.
basin_shapefile	Required. Shpefile of basin boundary.

Value

If successful, returns TRUE. Writes several files, including 1) a .asc file of the DEM with missing values in place of the roads, 2) SAGA files (.sdat, .mgrd) contining the filled DEM, and 3) a .asc file of the filled DEM clipped to the basin boundary.

Note

This function uses the raster function mask to delete the DEM elements covered by the buffered roads, and RSAGA function rsaga.close.gaps to fill in the deleted DEM cells.

Examples

## Not run: remove_roads("basin5.asc", "basin5_roads.shp", "basin5_boundary.shp")
