For my current project, I have about 65,000 addresses that need to be geocoded and then I need to find the closest (by driving distance) store out of roughly 1000 to each of these addresses.  I was originally working in STATA using Google Maps geocoding, but unfortunately Google has a limit of 2500 geocodes per day, making it unsuitable for my project.  I am looking into purchasing a license for either TomTom Multinet or NavStreets.  My questions are:

 

1. Is this project feasible using ArcMap 10 and Multinet or NavStreets?

2. Which is better, Multinet or NavStreets?  Or is there a better source?

3. Are there any other solutions outside of ArcGis?

4. How much to licenses for these datasets cost?

If you are working within the US, the geocoding and network analysis (which it seems like you would need to calculate driving distance) can be done using the ESRI Data & Maps CD that comes with ArcMap (http://www.esri.com/data/data-maps). We have an annual user license so we get an updated one every year. It includes address locators and road network files. ESRI also has a separate online geocoding service, but I'm not sure of the price. Geolytics also sells software for geocoding and there are some other free geocoders out there, but I believe all the addresses will need to be done in batches, even if there is no daily limit. The Texas A&M geocoder has been recommended to me, although I haven't tried it: http://geoservices.t...rvices/Geocode/

 

I'm not sure if driving distance/network analysis can be done outside of ArcMap. To do it within Arcmap, I believe you need a separate network analyst license, but you shouldn't need tomtom or navstreets if you are using the ESRI Data & Maps data.

Could you point me to the specific network layer that I could download?

If you set up a free account with ESRI, you can search through the link above to see if they have something usefull for you. I typed geocode and routing seperately into the 'search for groups' search box and had numerous free add ins available. Not all of them are free but a good amount are. Not for sure which one could work for you but happy hunting seeing if something does.
