Hi,
Please help I'm new at this side of the GIS business.
We are looking to derive products from aerial photography flown with laser
points. We have access to the Geotiff image and the laser points which are
in the format x,y,z. I need to know the products that can be derived from
this. Stuff like street centrelines, building footrpints, places fo
interest, street intersections, but also in the lines of DEM/DTM and 3-D fly
throughs.
With regards to DEM and DTM is there any way of defining specs for the
DTM/DEM so a client could get an idea of what he will be getting. Some of
the flying was done in urban areas so a 3D image and fly-through of the city
is needed. Also what software would be the best for the 3D stuff and do you
have any ideas on feature recognition software.
Do you have any ideas on other features or products that can be derived.
Thanks
Craig
