Hello all, I am wondering if you guys have come along free online geocoders which work well. Accuracy, Speed and Percentage successfully geocoded are all top priorities for me. Also, same question but for reverse geocoders.

Second, how would one test for accuracy of geocoded points? Thanks!

I've recently used the Yahoo geocoder and that seemed to work pretty okay. It's an area I'm not personally familiar with so I can't doublecheck the results easily, but out of 3000+ locations it managed to geocode everything. Pretty sluggish though, it took 20 minutes in FME to slug through that.

As for testing, put in a few nasty addresses that you are personally familiar with and see what they come up with. Something rural, something with a house number and letter etc.

Careful with what geocoder you use because often you may find geocoded addresses in the sea.

"There is much beauty that we fail to see through our own eyes teeming with life forms that give us that perception of our reality.  Leaves on the trees blowing gently in the wind, or scarily, the waves pounding through high surf, or lightly on a warm summer’s day; that opportunity to sit or swim in the water on a white beach.   That comfort to shout, “The universal conscious do you hear me?  I am alive, guide me dear logos towards the path of rightnesses.”  Earned what has been kept, no longer to be absorbed into a life filled with cold damn winds and  that stubborn fog clouding  my vision with nothing but darkness."

I recently used http://www.batchgeocode.com and found it to be really well done and reliable. It is quite slow however.

I use this too. although slow, I like it. Or for the tech-savvy and Canadians among the group there's geocoder.ca. They have an API that you can use to build an application that will geocode your addresses.
