Don't think I've ever seen a handheld computer. You mean something you can hold in one hand?

Yep. At one time there was a difference between a handheld computer and a PDA. Since the capabilities of the PDAs have come such a long way, the line is pretty fuzzy these days.mccabejc:Don't think I've ever seen a handheld computer. You mean something you can hold in one hand?
Robert Phillips:Here is a link I have that someone sent me from another list I am on.
mccabejc:I want to make a topographical map of a set of reefs, which are pretty much an extension of a local beach. If that's too much to accomplish, then at least I'd like to be able to draw an outline of the reefs without depth/topo information. I'm trying to figure out the cheapest and best way to do it. I'd like to do it at 0 cost, of course, and might pay some money on equipment only if I can use for other things.
I'm looking for some thoughts on ways to accomplish this. Here's what I've considered so far:
1. Accessed the Terraserver (http://terraserver.microsoft.com/) to find satellite images of the beach, hoping to see an aerial view of the reefs with sufficient definition to define the outline of the reef. Found the exact image I needed, but unfortunately, it didn't have quite enough definition. I guess conditions have to be just right. In any case, here's the photo if anyone is interested. It's the reefs surrounding the splotch of white at the bottom center of the image, where waves are breaking on some parts of the reef:

Thanks for any input.
