To centre the map on an object or location, enter:
* An object name.
* Latitude and longitude. This can be in decimal degrees (E.g: -23.666413, -46.573550) or degrees, minutes and seconds (E.g: 50°40'46.461"N 95°48'26.533"W or 33d51m54.5148sS 151d12m35.6400sE).
When checked, opens the Maidenhead locator converter dialog, which allows conversion between addresses, latitude and longitude and Maidenhead locators.
<h3>4: Display Beacon dialog</h3>
When clicked, opens the Beacon dialog. Initially, no beacons will be listed. To download the IARU Region 1 beacon list, click the download button in the top right.
The beacons will then be displayed in the table and on the map.
When checked, contours will be downloaded and displayed on the 3D map, showing the MUF (Maximum Usable Frequency) for a 3000km path that reflects off the ionosphere.
The contours will be updated every 15 minutes. The latest contour data will always be displayed, irrespective of the time set on the 3D Map.
<h3>8: Display coF2 Contours</h3>
When checked, contours will be downloaded and displayed on the 3D map, showing coF2 (F2 layer critical frequency), the maximum frequency at which radio waves will be reflected vertically from the F2 region of the ionosphere.
The contours will be updated every 15 minutes. The latest contour data will always be displayed, irrespective of the time set on the 3D Map.
* Whether images are displayed on the 2D map and whether 3D models are displayed on the 2D map.
* Whether labels are displayed giving the name of the object.
* Whether taken and predicted tracks are displayed and in which colour.
* How the image or 3D model is scaled as the zoom level changes.
For the 2D map, the settings include:
* Whether the 2D map is displayed.
* Which Map provider will be used to source the map images.
* When OpenStreetMap is used as the provider, a custom map URL can be entered. For example, http://a.tile.openstreetmap.fr/hot/ or http://1.basemaps.cartocdn.com/light_nolabels/
* When MapboxGL is used as the provider, custom styles can be specified.
For the 3D map, the settings include:
* The terrain provider, which provides elevation data. For a "flat" globe, terrain can be set to Ellipsoid for the WGS-84 ellipsoid.
* The buildings provider, which provides 3D building models. This can be set to None if no buildings are desired.
* Whether the globe and models are lit from the direction of the Sun or the camera.
* The camera reference frame. For ECEF (Earth Centered Earth Fixed), the camera rotates with the globe.
For ECI (Earth Centred Inertial) the camera is fixed in space and the globe will rotate under it.
* To set an object as the target. The target object will have its azimuth and elevation displayed in the text bubble and sent to the Rotator Controller feature.
* Setting the Device center frequency to the first frequency found in the text bubble for the object.
* Changing the order in which the objects are drawn, which can help to cycle through multiple objects that are at the same location on the map.
