Geocoding API this 'mashup' page utilizes is using the very good GDT/TeleAtlas road network base maps, so the quality of the results are typically as good or better than what I can accomplish with free data and desktop GIS geocoders. There are more advanced batch geocoding services available to academic users without charge from the USC GIS Research Laboratory: https://webgis.usc.edu/ Edward A.

We are looking for a good quality road network for Phoenix Arizona to allow students to geocode too. We have downloaded the Tigerline files, but they are not very good for this purpose. Can anyone provide us with suggestions for a source or two for high quality and free Phoenix street network data? thanks for your help, Andrew -- Andrew J.P.
