My many thanks and apologies to all for the recent request. I had many
folks send helpful information and several others remind me that a lot of
necessary info was missing from my request. That's what happens at 11:30pm.
I've realized it's not a simple solution by far given the state of the data
and it's attributes I am working with (in this case, roads in shapefile
format). My intent was to run a report to calculate how many km or (meters
or miles, etc. or whatever the unit length in the attribute table was in),
and given that is has several hundred thousand records, Excel chokes, so
does Access, and Crystal Reports bombs out. I suspect the units are in DD
since there are numbers like ".0029857" in the length field, and when I
change map units to km or meters, and then use the measure tool to measure
real world coordinates, it comes very close, for the given line segment, to
what is in the attribute table, but no telling really. In any event, it was
the thought that counted. Our client won't miss what they haven't asked for
anyway. Cheers and happy new years to all.
