Map Projection
The absolute Drupal, or full URL to a directory of image overrides for the OpenLayers interface.
The absolute Drupal, or full URL to a directory of css files to override the OpenLayers interface.
As Javascript is not allowed to get data from a different domain, a proxy is needed if you want to pull data from external sources.
The new                        adds native support for an HTTP proxy in Drupal!
Proxy module
Either using a helper map or manually entering in textbox, you can easily set the default center point and zoom levels.
The map projection determines what layers are avialable and obviously the projection of the map itself.
The display projection determines how features and other interactions are handled.
Overall, you don't need to change these.
