[postgis-devel] Calculating flow direction

[George Silva]

Hello PostGIS developers,

I just built a flow direction function for WKT Raster. I know it's not the
most efficient, but looks like it works.

I would like (if you have the time/interest) to test it and report
inconsistent results.

I'm working on function for identifying sinks, removing sinks and creating a
accumulated flow raster.

Your comments are most welcome. The function is the attachment.
