addTopoLines — addTopoLines • ProcessSpace

Derives 1-unit and 5-unit contour lines from the DEM over the analysis area, for the overview map.

addTopoLines(transectObject, rasterDir = "GeoData/Raster/ChildsDEM_m.tif", ...)

Arguments

transectObject: Object created by the generateCrossSections function.
rasterDir: File path of the DEM raster (unused when the DEM is already stored on the transectObject by processSpace).
...: Ignored (accepted so pipeline wrappers can pass shared arguments through).

transectObject with $plotDataContours1ft and $plotDataContours5ft added (sf line layers in WGS84).
