<h1>Map Feature Plugin</h1>
|
|
|
|
<h2>Introduction</h2>
|
|
|
|
The Map Feature plugin displays a world map in 2D and 3D. It can display street maps, satellite imagery as well as custom map types.
|
|
On top of this, it can plot data from other plugins, such as:
|
|
|
|
* APRS symbols from the APRS Feature,
|
|
* Aircraft from the ADS-B Demodulator,
|
|
* Ships from the AIS Demodulator,
|
|
* Satellites from the Satellite Tracker,
|
|
* Weather imagery from APT Demodulator,
|
|
* The Sun, Moon and Stars from the Star Tracker,
|
|
* Weather ballons from the RadioSonde feature,
|
|
* Beacons based on the IARU Region 1 beacon database and International Beacon Project,
|
|
* Radio time transmitters,
|
|
* GRAVES radar.
|
|
|
|
It can also create tracks showing the path aircraft, ships and APRS objects have taken, as well as predicted paths for satellites.
|
|
|
|
|
|
|
|
|
|
|
|
3D Models are not included with SDRangel. They must be downloaded by pressing the Download 3D Models button in the Display Settings dialog (11).
|
|
|
|
<h2>Interface</h2>
|
|
|
|
|
|
|
|
<h3>1: Find</h3>
|
|
|
|
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).
|
|
* A Maidenhead locator (E.g: IO86av).
|
|
* An address (E.g: St Katharine's & Wapping, London EC3N 4AB)
|
|
|
|
<h3>2: Map Type</h3>
|
|
|
|
Allows you to select a 2D map type. The available types will depend upon the Map provider
|
|
selected under Display Settings (7).
|
|
|
|
<h3>3: Maidenhead locator conversion</h3>
|
|
|
|
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.
|
|
|
|
* Double clicking in a cell in the beacon table in the Callsign or Location columns, will centre the map on that beacon.
|
|
* Double clicking on the Frequency column will set the Device center frequency.
|
|
|
|
|
|
|
|
<h3>5: Display IBP Beacon Project Dialog</h3>
|
|
|
|
When clicked, opens the International Beacon Project dialog. The IBP consists of 18 HF beacons around the world,
|
|
that each transmit once on each of the frequencies 14.100, 18.110, 21.150, 24.930 and 28.200MHz every 3 minutes, for 10 seconds.
|
|
The IBP dialog shows which of the beacons should currently be transmitting.
|
|
|
|
|
|
|
|
* Double clicking in a cell in the Callsign column will centre the map on that beacon.
|
|
* Double clicking in a cell in the Frequency column will set the Device center frequency.
|
|
|
|
More details of the IBP can be found at: https://www.ncdxf.org/beacon/beaconfaq.html
|
|
|
|
<h3>6: Display Radio Time Transmitters dialog</h3>
|
|
|
|
When clicked, opens the Radio Time Transmitters dialog.
|
|
|
|
* Double clicking in a cell in the table in the Callsign or Location columns, will centre the map on that transmitter.
|
|
* Double clicking on the Frequency column will set the Device center frequency.
|
|
|
|
|
|
|
|
<h3>7: Display Names</h3>
|
|
|
|
When checked, names of objects are displayed in a bubble next to each object.
|
|
|
|
<h3>8: Display tracks for selected object</h3>
|
|
|
|
When checked, displays the track (taken or predicted) for the selected object.
|
|
|
|
<h3>9: Display tracks for all objects</h3>
|
|
|
|
When checked, displays the track (taken or predicted) for the all objects.
|
|
|
|
<h3>10: Delete</h3>
|
|
|
|
When clicked, all items will be deleted from the map.
|
|
|
|
<h3>11: Display settings</h3>
|
|
|
|
When clicked, opens the Map Display Settings dialog:
|
|
|
|
|
|
|
|
The top half of the dialog allows customization of how objects from different SDRangel
|
|
plugins are dispayed on the 2D and 3D maps. This includes:
|
|
|
|
* 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.
|
|
|
|
* API keys, required to access maps from different providers.
|
|
|
|
Free API keys are available by signing up for an accounts with:
|
|
|
|
* [Thunderforest](https://www.thunderforest.com/)
|
|
* [Maptiler](https://www.maptiler.com/)
|
|
* [Mapbox](https://www.mapbox.com/)
|
|
* [Cesium ion](https://cesium.com/ion/signup)
|
|
|
|
If API keys are not specified, a default key will be used, but this may not work if too many users use it.
|
|
|
|
The "Download 3D Models" button will download the 3D models of aircraft, ships and satellites that are required for the 3D map.
|
|
These are not included with the SDRangel distribution, so must be downloaded.
|
|
|
|
<h3>Map</h3>
|
|
|
|
The map feature displays a 2D and a 3D map overlaid with objects reported by other SDRangel channels and features, as well as beacon locations.
|
|
|
|
* The "Home Station" antenna location is placed according to My Position set under the Preferences > My Position menu.
|
|
* To pan around the map, click the left mouse button and drag. To zoom in or out, use the mouse scroll wheel.
|
|
* Single clicking on an object in the map will display a text bubble with additional information about the object.
|
|
* Right clicking on a object on the 2D map will open a context menu, which allows:
|
|
* 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.
|
|
* Setting the object as the tracking target on the 3D map.
|
|
|
|
The 2D map will only display the last reported positions for objects.
|
|
The 3D map, however, has a timeline that allows replaying how objects have moved over time.
|
|
To the right of the timeline is the fullscreen toggle button, which allows the 3D map to be displayed fullscreen.

<h2>Creating 3D Models</h2>
|
|
|
|
If you wish to contribute a 3D model, see the https://github.com/srcejon/sdrangel-3d-models project.
|
|
|
|
<h2>API</h2>
|
|
|
|
Full details of the API can be found in the Swagger documentation. Here is a quick example of how to centre the map on an object from the command line:
|
|
|
|
curl -X POST "http://127.0.0.1:8091/sdrangel/featureset/0/feature/0/actions" -d '{"featureType": "Map", "MapActions": { "find": "M7RCE" }}'
|
|
|
|
And to centre the map at a particular latitude and longitude:
|
|
|
|
curl -X POST "http://127.0.0.1:8091/sdrangel/featureset/0/feature/0/actions" -d '{"featureType": "Map", "MapActions": { "find": "51.2 0.0" }}'
