Use your mouse to define an area of interest on the map, or type the Geographic coordinates into the North, East, South and West fields to define a bounding box. Note that all coordinates are to be entered in GDA94 datum, for a minimum area of 0.1 degrees by 0.1 degrees (approximately 10km by 10km). If you define a search area which is less than the minimum, the coordinates will be expanded by default. After selecting your area of interest, click on the Use Extent button to confirm your selection and close the window.
