from the manual of v.to.db
http://grass.osgeo.org/grass64/manuals/html64_user/v.to.db.html
slope: slope steepness of vector line or boundary
any idea which is default unit of the calculated slope?
units=string
Units
mi(les),f(eet),me(ters),k(ilometers),a(cres),h(ectares),r(adians),d(egrees)
Options:
mi,miles,f,feet,me,meters,k,kilometers,a,acres,h,hectares,r,radians,d,degrees
with the option "unit" the output unit could be definded.
would r,radians or d,degrees make sense?
-----
best regards
Helmut
