[Qgis-user] TPI landform classification

[Lester Anderson]

Hello all,

I have been trying to run the TPI Landform classification algorithm in
QGIS (v2.10) and each time it fails by just hanging - the SAGA module
keeps on using more and more memory.

The grids I have tried are all Geographic (Long-Lat) but that should
not be an issue (I would have thought). As a test I ran the same
module direct from SAGA and again it still gets stuck.

Any ideas how this should run or why it fails - it almost looks like
it is stuck in a loop.

Cheers

Lester
