| Apr 15, 2013 at 17:25 | comment | added | Isaac | They all return some form of accuracy information, I think, though it's often category-level; but I'm also concerned about the case where two different services both claim to have found an address-level match, but they put the address in significantly different places. | |
| Apr 15, 2013 at 17:23 | comment | added | Matt | How many of the services return accuracy estimates? (Ideally, you would just pick the most accurate geocode results based on the accuracy reports.) | |
| Apr 15, 2013 at 17:11 | comment | added | Isaac | @Matt: Yeah, I'm planning to tackle that from the scripting/programming side—I'm thinking that I can use a framework-provided distance-between-locations function to see how far apart the lat-lon pairs from different services are to sort out the addresses that come up roughly matching across services from those that don't. | |
| Apr 15, 2013 at 16:55 | comment | added | Matt | Combining the best results from various services will probably require some advanced GIS knowledge, or proficiency with scripting/programming, or serious Excel ninja skills. The advantages/disadvantages may be different depending on which of these ways you prefer. | |
