Check Box
When you click on a region or country link a new window will open with a checkbox of all the GIS and satellite image layers available for that selection. Check those layers that you would like to be visible when you open your map. The active fires layer and country outlines will be selected by default.

Note: You should consider the speed of your internet connection when choosing layers - loading a image layer can take a long time unless you have a relatively fast internet connection!
After selecting your layers, click the "Open Map" button to load the map containing the layers of your choice.
