Here is what I have learned :

1. Forestwalker produces ways that intersect. Some of them could be just one step apart, but it creates lines.

2. It creates alot of nodes that all point to the same beginning.

3. it creates endless loops at the end of the way.

Solutions :
1. track all points in a hash (lat/long) dont allow duplicates.

2. dont allow duplicate points in the ways.

Also what I have learned, we need to process the satallite photos. Can use some imagemagick or gimp scripts.

Ideally the script would be able to close areas off. create smaller areas out of big ones.

the intersections could be closed off as they are.

The rivers could be found with processing of the image. Larger features can be found with processing.

One big problem is the scanning for features, I would like to be able to scan for features without specifing points.

Ideally the entire thing can run as a python plugin in gimp.

I think that gimp would be great for osm, the data could be paths, the landsat could be image layers.
