For the defined region I want to create a map of the Manning's n friction
value (0.030) in each cell. v.in.ascii tells me it cannot find the input
text file:
v.in.ascii -n -b input=manning.txt output=manning format=point
ERROR: Unable to open input file <manning.txt>
The file has no coordinates, only the single value 0.030. I am not finding
what is missing here. A pointer is needed.

Rich,
If you want to create a raster map with an uniform value, just use mapcalc:
r.mapcalc exp='manning=0.03'
And that's it.

Laurent,
That is much simpler than what I tried to do.
Thanks,
