What is the best mapping program you have seen and /or used? I have TOPO USA and just ordered their 3.0 version. It has the entire US on 6 CD's. I have also go the Maptech CD set for Texas and it has 17 CD's for JUST Texas. The Maptech is awesome, but I am disappointed in the TOPO USA. In fact, I will be returning it for a refund. Is there a better program out there that I have not found? The TOPO USA does not have the details that the Maptech has. The Maptech has a lot of editing capabilities that TOPO USA can not match. What is your favorite program?
