Hello. I'm looking for a somewhat basic ASP.NET mapping software (or code for doing what I need in Virtual Earth or Google Maps or something) that allows me to not only add layers (such as US Counties) but to also be able to draw a polygon (like a square or circle) and within that polygon have it automatically calculate the percentage of each layer section.
So, for example, I put a layer on a US map of all counties. I draw a circle around 4 different counties. Based on the circle I drew, it shows the percentage of each county within (like 22%, 43%, 34%, 1%). It sounds or seems like it would not be too difficult, but I've had some experience with drawing polygons on Virtual Earth maps and for the life of me, it was hard enough just finding the damn area of a custom polygon (if I could at all) nevertheless percentages of objects encompassed in a layer.
Anyway, I know this may be a horrible place to post a topic like this, but I just don't really know where to start, other than the fact it must work with our ASP.NET web apps. Thanks!
