Monitor - Panel Map

You can use the Map panel to display a map section with the location of the current alarm. The prerequisite for this is that the location is transferred with the address and coordinates when an alarm is triggered.

💡 All adjustments to the panel are only applied when the editing view is exited using the Save button.

1️⃣ The input field for the title allows you to add a heading to the panel. The font color of the heading and the background color of the panel can be adjusted for the visual design.

💡 You can find information on the advanced formatting options here.

2️⃣ You can use the zoom level to zoom in or out of the map section.

3️⃣ The function, Show location of alerted units, shows you the last position of your units on the map known to the system. The prerequisite for this is that the positions of the respective units are transmitted to GroupAlarm. Details on the positions of units can be found here.

Automatically zoom to units allows you to have the monitor automatically zoom in on the units that are displayed. The monitor will always attempt to zoom in as closely as possible to the units, in line with your selected zoom level. However, if several units are located at a considerable distance from one another, this will also cause the monitor to zoom out in order to display all units. This function requires that Show location of alerted units is enabled.

4️⃣ The Units field acts as a filter if you do not wish to display all units associated with a position. Simply select the units you wish to display here.

5️⃣ By default, OpenStreetMap is used as the basic view for the map. However, you can also select other maps via the drop-down menu. Select your preferred map view here.

Additional layers with additional information can then be placed over the basic view of the map. A selection is also available for this purpose. These include, for example, water extraction points, locations of defibrillators or assembly points.

You can also place a DWD (German Weather Service) layer over the map to obtain information about the weather conditions at the location. Various layers such as precipitation radar or weather warnings are also available here.
As the DWD layer could obscure the actual map depending on the weather conditions, you have the option of making it individually transparent.

6️⃣ GeoJSON URL allows you to integrate your own GeoJSON data. This requires the active URL to a valid GeoJSON file.

⚠️ The use of the GeoJSON URL function requires knowledge of handling GeoJSON data.

To include possible authentications in the HTTP header, use the Header field and Value fields.

If your GeoJSON file contains its own icons for markers within the properties field, you can include this icon using the Marker icon selection field. Three selection options are available here:

If you receive the GeoJSON from the RescueTABLET interface, you can select RescueTablet there directly.
If you want to use the icon behind a URL as a marker icon, use Custom URL.
If you want to select your own JSON field that contains a URL to an icon, select Own path. You can now enter the JSON path within the properties in the field below. For example, use marker.iconURL to access the icon URL within the properties field in the example below.

{
    "type": "Feature",
    "geometry": {
        "type": "Point",
        "coordinates": [
            9.101485,
            50.21362
        ]
    },
    "properties": {
        "marker": {
            "iconURL": "https://example.com/icon.png",
        }
    }
}

7️⃣ The Show the location of Things function enables the positions of Things, which you can then set up under Things Configuration.

Things Configuration

Things allows you to display various pieces of information that you have stored in Things on the Static Map panel. However, this requires that your Things database contains at least one coordinate field. A possible use case could be, for example, the location of building sites or road closures.

To retrieve the data from Things, you must first select the desired entity under Things Configuration.

💡 You can find out more about Things here.

1️⃣ Once you have selected the entity, you can open the configuration tab. During configuration, you can, of course, change the entity you have selected at any time.

2️⃣ The Coordinate Field is a mandatory field. Without the relevant coordinates, the data cannot be displayed on the map. Your Things database must therefore have a corresponding field containing valid coordinates (example: 50.76273,6.0774249)

3️⃣ You can customise the marker on the map. The Alignment determines where the pin should be placed on the map in relation to the text. The Cluster Radius helps you to separate a large number of markers that are close together, so that they do not overlap. Colour and shadow are used for visual design.

4️⃣ In the Display configuration section, enter text describing what the pin on the map represents. This is also a mandatory field for the pin to be displayed. Here, you can enter either a fixed text or add variables by clicking on them. These variables are then populated with data from the Things database. The available variables depend on the data fields you have defined in Things.

5️⃣ Optionally, you can add a condition for the marker. This condition must be met for the marker to be displayed. The values for this condition are also retrieved from your Things database. This means that, for example, in the case of recurring short-term closures, you could activate or deactivate the display by making a simple yes/no change in Things.
