hi,

how can i calculate the mean aspect of a catchment?

the calculation of the aspect is easy with spatial analyst but how can i get the MEAN ASPECT? The problem is i.e. the the sector NORTH ranges from 337.5° to 22.5° and if i just calculate the MEAN with zonal statistics i get wrong angles for the results.

can anybody give me a useful hint how i can calculate the mean aspect?

thanx
c.
