Hello Sockmonkey I am new to the community and been interested in mapping for years for my backpacking trips in Mexico. I just started out in making maps in ArcGIS but I came to this page via a search in google and found out that you already have the Mexico topos ready however I encountered that with the tutorial of installing maps in my basecamp there are problems with some programs in order to have your maps ready for base camp. I managed to download the MX-MexicoTopo Disk Image file for windows but I encountered that the program necessary to download these files to basecamp compatible files is no longer available. Do you know where can I get a program to install your maps? Thanks in advance for your help and thank you for your contribution to world mapping!!!
