Thanks guys - great info! FWIW here are my results on our ponds/lands.

1. The Google info is at least 5 years old more like 7-8.

2. The palininmeter info via Google is way off on our ponds 20% under on one , 15% under on another and 20% over on the third. Part may be operator error and part the nature of the ponds.

3. The Mapquest Ariel photo info is at most 18 mths old and much clearer than Google or MSN.

4. MSN Livesearch info is about the same age and functions like Google Earth.

Do either Livesearch or Mapquest have a palininmeter function ?
