#1228: r.surf.area manual needs updating
-------------------------+--------------------------------------------------
Reporter: cmbarton | Owner: grass-dev@…
Type: defect | Status: new
Priority: minor | Milestone: 6.4.1
Component: Raster | Version: unspecified
Keywords: r.surf.area | Platform: All
Cpu: All |
-------------------------+--------------------------------------------------
The manual for r.surf.area seems to be out of date with respect to the
information generated by the program. Here is what the module reports:
r.surf.area input=elevation.dem@PERMANENT
[[BR]]
Null value area ignored in calculation 2.394900e+06
[[BR]]
Plan area used in calculation: 2.644920e+08
[[BR]]
Surface Area Calculation(low, high, avg): 2.701080e+08 2.732753e+08
2.716916e+08
[[BR]]
Current Region plan area: 2.654802e+08
[[BR]]
Estimated Region Surface Area: 2.727067e+08
[[BR]]
Done.
But here is what the manual says it reports:
Reported totals are:
[[BR]]
1. "Plan" area of NULL values within the current GRASS region
[[BR]]
2. "Plan" area within calculation region (rows-1 * cols-1 * cellarea)
[[BR]]
3. Average of the minimum and maximum calculated 3d triangle area within
this region
[[BR]]
4. "Plan" area within current GRASS region (rows * cols * cellarea)
[[BR]]
5. Scaling of calculated area to current GRASS region (see NOTE)
Maybe it is just a simple change of wording for each entry, but someone
who is familiar with the command ought to check to ensure that this is all
that is needed
