Easily Enrich Address Data
I have selected this service because it is able to process large numbers of addresses quickly and efficiently...I have used this service before and am familiar with and confident in their work. I have taken sample data sets in which the true coordinates are known, and contrasted the accuracy of their estimates with those produced by other leading geocoding services. The differences in accuracy were minimal.
