I have a raster that I think was "combined" using an ArcGIS function.
I am wondering if there is a way to extract just one raster layer from the combined dataset in order to use it separately, using R.
If you want to see the data it is available here
It takes this form in R:
class : RasterLayer dimensions : 10995, 10349, 113787255 (nrow, ncol, ncell)resolution : 100, 100 (x, y)extent : -446880, 588020, -612570, 486930 (xmin, xmax, ymin, ymax)coord. ref. : +proj=aea +lat_1=34 +lat_2=40.5 +lat_0=0 +lon_0=-120 +x_0=0 +y_0=-4000000 +datum=NAD27 +units=m +no_defs +ellps=clrk66 +nadgrids=@conus,@alaska,@ntv2_0.gsb,@ntv1_can.dat data source : G:\Faculty\Mann\Share\Fire\FRAP_FireThreat\FireThreat.tif names : FireThreat values : 0, 255 (min, max)attributes fields : ID Rowid COUNT FUEL_RANK FROTCLASS URBAN THREAT THREAT2PEOPLE min : 1 0 1 -1 0 0 -1 -1 max : 97 96 5360409 3 3 1 4 424
