I need to find the mileage for over a million sets of points in the US. I need a network dataset of eSRI street data. I put the sdc street data into a geodatabase feature class (almost 8 gigs!).
QUESTIONS:
Do I need a network dataset, - can I find the mileage between the sets of points, using sdc street data without creating a network dataset? (I read somewhere this can be done, if so How?? the Network analyst is greyed out until I have a nd in the map!)
Do I need this data in a feature class to create the network dataset?
Can I create a network dataset from the sdc layer? again, how to do this if it's possible?
thanks!!
