It pains me that I know little about this area of technology, but I guess it's not possible to know everything. A colleague has a bunch of AutoCAD files that have to do with urban planning, and he wants to extract the following information from the equivalent DXF files:

• Each corner point of each building lot with a latitude & longitude. Note that the lat. & long. may not be embedded in the file, but I am assuming the points are referred to on a relative scale so that they could be translated into lat & long data
• The colour of each corner point (this is relevant information, added by the planner)
• The area of each building lot - I believe that AutoCAD is calculating this.

I have had a look at CPAN and haven't really found anything that will help me. My research on DXF tells me that it's a very low-level file, so I'm guessing that the information required may not even be available in the DXF file.

If some monks have comments, thoughts, suggestions about where to begin, I'd appreciate it. Thanks!
