Use a text editor such as notepad to edit the "config.ini" file in the game directory. Change the DebugPanel = 0 line to DebugPanel = 1. Start a new game and press ` or ~ and and a debug panel with various options will appear on the right side. For example, select the "Reveal All" option to view the full map. Be carefull and have a backup ready of the file you modified.

Instead of randomly selecting a successful looking civilization and sending spies on a whim, look to the intel that is provided more readily. If you check for possible trade routes and notice that you can gain science knowledge through trade, that also means you can send a spy to that civilization and improve yourself using more devious measures. It's a great way to avoid wasting precious resources.
