Dear Ed & All,
Could a brief reminder of the particular topic the conference is supposed to be discussing this week be provided please ? Thanks.
In the meantime, I'd like to raise another SAM issue. Many of us will be getting or already have geo-referenced, digital aerial photographic imagery with a DTM. Following James Dinn's info on MAGIC, wouldn't it be more sensible to digitise SAM polygons using digital aerial imagery with a DTM as the base, so that the boundaries actually have a 3-D expression. This shouldn't cause any problems for map GIS users but will provided added information for those of us using aerial imagery to check things out.
Cheers,
Neil
