# This is a test to register and unregister raster maps in
# space time raster input.
# The raster maps will be registered in different space time raster
# inputs

# We need to set a specific region in the
# @preprocess step of this test. We generate
# raster with r.mapcalc and create two space time raster inputs
# with absolute time
# The region setting should work for UTM and LL test locations
