GRASS quickstart - Vector Modules

Reported by: micha Owned by: hamish
Priority: normal Milestone: OSGeoLive6.5
Component: OSGeoLive Keywords: docs, 6.5, GRASS
Cc: live-demo@…

Description

The quickstart section on Vector Modules suggests creating attributes for the basins area vector with v.rast.stats, then filtering based on stddev < 50. In my trial all the stdev values where below 15. I suggest to change the quickstart to "stddev<10"

It matters which dataset you were using and which resolution you had the region set at the time.

Were you using the spearfish or north carolina dataset?

If spearfish, were you using the elevation.dem (30m) or elevation.10m data?

Replying to hamish:

The nc_basic_spm dataset, using the elevation raster. No changes to the region, I just walked thru the quickstart.

If spearfish, were you using the elevation.dem (30m) or elevation.10m data?

I've modified the quickstart to make it clear which maps to pick. In general I thought to leave it generic, but for r.watershed the number of threshold cells is map resolution dependent.

thanks for noticing it, Hamish
