You have just made my day! I have, in the last couple of weeks,
manually traced the Landsat imagery of a number of the larger Irish
lakes. The process was tedious and there was no way I could sustain it
even to the level where I could complete the most important ones.

Lakewalker works like a charm, so my hat is off to you.
