I need to check the accuracy of the locators between Esri's Streetmap 14_2 and Streetmap 15_1. The two layers need one to one distances measured between points that have the same attributes i.e. same address, city, state, and zip. The tables are exactly the same essentially with the exception of X and Y coordinates. Would the point distance tool be the best option? A colleague suggested the point distance tool and selecting the points individually. With 150 million records, that seems like it would take a while. Any suggestions?
