I'm trying to get a "MEASURE" for Points along a route. I need ARCGIS10 Desktop Linear Referencing tools or other application to use a unique identifier to match the Lines in the route to points scattered offline. I'm trying to avoid running the Linear Referencing Locate along route tool separately for over 80 unique Point/Routes.
I've Tried the following:
Buffer the Points to Intersect the line -> Run the Locate along route tool selecting the Parent ID for the Output - > In the Output Table and using Field Calculator, Set up an Python "If/Else" Statement:
def myCalc (ID1,ID1_Orig): if(ID1==ID1_Orig): return 1 else: return 0
Codebook - Sort= myCalc(!ID1!,!ID1_Orig!)
Then Deleting all returns with "0" in the "Sort" column.
