I was using the new City of Ottawa eMap for a work project last week, and noticed it has a great application for us golfers. They have the entire region on air photos (2002 & 2005) which you can zoom in on. Here is the link. http://www.ottawa.ca/residents/emaps/index_en.html

(i) Click eMap.
(ii) Once you have zoomed in on your favourite golf course, then right click; select view and then distance.
(iii) Then you can point your start position and drag. The distance in feet will be indicated.
It is very accurate. Try it on something you know the size of ie. your property frontage/depth, and you will see.

Tried it on a few courses, and it was very accurate. It actually makes you think out the distances and certainly has me wondering why I took some chances on certain holes. You can see the exact distances to carry water/bunkers from different tee positions.

If I spend the winter studying my club course, I will not even have to look at the GPS next year.

Have some fun and give it a try............
