Measuring distances of multiple roads
Posted 25 May 2011 - 09:37 AM
I am working on totaling up all road miles in a given county, municipality, or Congressional District within a State. I can select all of the roads by feature, but I have not found a good way to total up their linear distance. Any ideas?
Thanks in advance!

Open the attribute table, right click on the length field, and choose Summarize.
If you are doing any editing, make sure they are in a GDB and the length field will automagically update.
Unfortunately the Attribute Table provided by the Census Board contains only these fields:
FID, Shape, StateFP, CountyFP, LinearID, FullName, RTTYP, MTFCC
So there is no field that details the lengths of the selected roads.

Add a new field, then right-click and select 'Calculate Geometry' and choose Length. Then perform the summary.
You sir, are a God among men. Can't thank you enough for your assistance.
