Where can I get a tutorial or manual on OptGeo?
The only help available about OptGeo is the one from the application itself. After the software has been installed on your computer, go to /Optgeo/aide/en/optgeo.html in Program Files and you will have the possibility to read the available help. However, you should notice that the help is in French since it's a French application.
