Parameters:
- input=name [required]

- FP raster to store output
 
- radius=integer [required]
 
- Radius of neighbourhood in map cells
 
 
r.prominence calculates the average difference between a
central cell and its neighbors. It approximated the terrain 'ruggedness'
by looking at average differences in elev_lid792_1m within a given neighborhood
The 
radius is specified in number of map rows/columns.
North Carolina sample region:
g.region raster=elev_lid792_1m
# get region rows/columns
g.region -g
# calculate prominence (radius of 50 map rows)
r.prominence input=elev_lid792_1m output=prominence radius=50
# visualize over shaded DEM
r.relief input=elev_lid792_1m output=elev_lid792_1m_shaded
d.mon wx0
d.shade shade=elev_lid792_1m_shaded color=prominence
