Melvs

My name is Melvin Lizano. GIS analyst working in a private company and I teach in gis issues at the University of Costa Rica. I want to start collaborating with the forum, he had not done so because I did not know how to do, and because I want to see the entire forum, hope I can enable the rest of the forum again to start up some books and other materials that I have available . Regards, Melvin PS Thanks in advance for the help you can give me
