Hi Paolo,
In my experience the plugin only works with graphs in WGS84 (or any lat/lon
system). And even then it's often a pain.
Best wishes,

Hi all.
I keep on getting "Start point not on the road" error. I tried different
topology settings (up to 99, the maximum allowed), to no avail.
Any hint?
Thanks.

wild guess, it should have be `--interface-description` not
`--interface--description`.

Hi all -
I'm running QGIS 1.6.0 and GRASS 6.4.1 and I'm getting weird errors when
trying to run a few tools inside GRASS. I've imported an ESRI grid into
GRASS without difficulty and can use some spatial analysis tools (slope,
aspect, etc) but when I try to run r.shaded.relief or r.mapcalculator,
Please refer to the QGIS manual on how to start with GRASS. You'll need
to create a location/mapset, import the raster in it and then use
r.to.vect
cheers

The Grass toolbox appears inactive.
The image that I georeferenced does not origin in Grass. It was an jpg image.
I selected the layer with raster image, click in Grass plugin and the toolbox
stay disabled.

Hello,
there are some R2V (automatic raster to vector converter) which try to

I've some experiences with VPMax, VPStudio which can find rotated text
too.
The result is highly depending on the qualy of the map and of cour

Hello,
This might seem a Little off topic, but maybe someone here can help me.
I need to extract toponomical data from old digitized paper maps. I wish to
explore *Optical character recognition (OCR).
Does anyone has a suggestion/experience with this kind of challenge?
Thank you,
André Mano
