  • rBuildVRT: Create a Virtual Raster Mosaic from a set of Raster file on disk.

rOverlay(las, res, start = c(0, 0), buffer = 0)
rMergeList(raster_list)
rBuildVRT(file_list, vrt)

Arguments

las

An object of class LAS

res

numeric. resolution of the raster

start

buffer

numeric. Extend the bounding box of the LAS object to generate a RasterLayer larger than the point cloud
