Hi all and thanks for help,
I have a shapefile "canopy_height.shp" with two column "a" and "b". I wish
to do a-b and to obtain a third column ("a-b"). I am using the R+SAGA
module: "Table calculator for shapes", and all run good, but when I open the
shape-file after (in ARCMAP) I don't see the third column. There is a
option to save a new shape-file?
Thanks for Help
Ale
