My name is Nathan Rover, I'm a software developer from Troy, Missouri. I found a link to this page from geocaching.com (one of my favorite past times). I was interested in helping with the mapping of the United States. I can do GPS leg work, but I'm under the impression there is an attempt to import census data. How will this effect the data collected by GPS mappers. It looks like there might be some issues with the import process, if I could be of any help please let me know. I'm a software developer who can program in C++, VB.NET, Python, ASP and T-SQL. Everyday I manage small SQL server setups, and I have some experience with MySQL and Linux. I'm under the impression that is what you are using for this project. I also have a handful of IBM X330 in a rack in my office that could be used to supply some processing power if needed.
