xyz2tif | R Documentation |
Read xyz data, generate a GeoTiff file and optionally returns a raster* object.
xyz2tif(xyzFN = NULL, epsgCode = "25832", returnRaster = TRUE)
xyzFN |
ASCII tect file with xyz values |
epsgCode |
"25832" |
returnRaster |
logical. return as raster if TRUE |
object of class raster*
## Not run: ##- libraries require(uavRst) setwd(tempdir()) ##- get typical xyz DEM data in this case from the Bavarian authority utils::download.file("http://www.ldbv.bayern.de/file/zip/10430/DGM_1_ascii.zip", "testdata.zip") file<- unzip("testdata.zip",list = TRUE)$Name[2] unzip("testdata.zip",files = file, overwrite = TRUE) ##- show structure head(read.table(file)) ##- create tiff file ##- NOTE for creating a geotiff you have to provide the correct EPSG code from the meta data xyz2tif(file,epsgCode = "31468") ##- visualize it raster::plot(raster::raster(file)) ## End(Not run)
