Following the example on the r.topidx man page I ran the two following commands:
r.mapcalc "house_elev = if (isnull(aberDEM), aberDEM, house_catchment)" r.topidx in=house_elev out=house_tci I can find no output. house_tci does not display in a monitor, running r.stats -Anc house_tci out=house_stats produced an empty file, and so did r.reports house_tci What have I missed here that I find no output at tall?
