When working with TIGER line shp data at county level scale the labeling of roads, rivers, railroads, etc. is cumbersome due to all of the tiny line segments. Merging the dozens of segments that comprise a particular road or river will result in much cleaner labeling. The only problem is the amount of tedious work this requires. Anyone know of a Python script that will automate this process? It needs to find all records with the same name and merge them into one record. I thought ET Geowizards had a tool for this but can't seem to locate it.
If the Dissolve tool suggested in my comment doesn't work this shouldn't be too big a hassle to script.
If there is a computational bottleneck you might run into the same problem as with the Dissolve tool. You can always break your data into chunks to make it more managable.
