Three tabs are available in the application settings: User, Resource, and  Maps. Here you can select the application language, date and time format, measurement system, and resource, configure the search for cultivations, specify work shifts and the priority of fuel sensors, add maps, and so on.

You should save changes to the settings separately for each tab (the Save button at the bottom of the screen).

User

On this tab, you can change the user settings: select a language, date and time format, the first day of the week in the calendar, and enable the developer mode.

Resource

This tab contains the settings which are applied to the resource. Here you can select the resource and measurement system, configure the search for cultivations, specify work shifts and the priority of fuel sensors.

Resource selection

This section includes one parameter.

Search settings

The parameters available in this section are described below.

Work shifts

In this section, you can specify the start and end time of work shifts and use them in reports.

Priority of fuel sensors

In this section, you can configure the calculation of the consumed fuel volume for the units which have several fuel sensors of different types. The fuel volume is displayed in the cultivation properties (the Fuel spent field) and in the reports (the Fuel spent column).

If a unit has several fuel sensors configured, their values are summed up by default. To use the values of only one type of sensor, activate the switch. Drag the lines with sensor types to the required positions to determine their priority. The sensors of the type which is located higher on the list are used first. If they have no data, the sensors of the next type in the sequence are used, and so on. Also, the type of sensor with a lower priority can be used when data from this sensor is received on the majority of track segments.

The values of fuel sensors are taken from the Statistics table in Wialon (the  Consumed by ImpFCS,  Consumed by AbsFCS,  Consumed by InsFCS,  Consumed by FLS  rows).

Measurement system 

Here you can select the measurement system which should be used in the application to indicate the units of area, distance, volume, and mass. There are three variants:

• Metric (hectares, kilometres, metres, litres, kilograms);
• American (acres, miles, feet, gallons, pounds);
• Custom.

In the custom measurement system, you can indicate the measurement units available in the metric and American systems. 

Maps

Here you can add and delete your own maps and their settings. The following actions are available:

• add a map,
• import map settings from JSON,
• export map settings to JSON.

Adding a map

You can add two types of layers to the application:  tile layer and  WMS.

To add a map, follow the steps below.

1. Find the required map (e.g. the one like this). Find out the server address (URL) of the map and its parameters.
   For the map from the above example, the server address is as follows:
   https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x }
   Parameter:

   {
       "attribution": "Tiles © Esri — Source: Esri, i-cubed, USDA, USGS, AEX, GeoEye, Getmapping, Aerogrid, IGN, IGP, UPR-EGP, and the GIS User Community"
   }

2. Press the Add button in the application. 

3. Indicate the following:

   • Title. The text that should be displayed in the layer selection menu.
   • URL. The server address. If the type of layer selected below is a tile layer, you should replace the coordinates in the URL with the variables {x}, {y}, {z} in the corresponding order (see the example from paragraph 1).
   • Tile layer/WMS. Selection of layer type. It depends on the server. If you do not know for sure, try out each of the options.
   • Overlay. When this option is activated, the layer is shown on top of the others. It is applicable, for example, to the layer of traffic jams or a cadastral layer.
   • Time layers. The option which allows you to see different versions of the map depending on the selected date. It is available only for WMS maps. You can use maps which support time layers to observe the state of the fields, weather changes, and so on.
   • Parameters. JSON, which is used as an option when creating a layer (see Leaflet TileLayer Options). In our example, attribution is sent in the parameters.
   

4. Save the settings.
   As a result, a new layer should appear in the map selection menu.
   

   This setting is applicable to the resource.

Importing and exporting map settings

Import and export of map settings is provided to make their transfer between resources more convenient.

The Export to JSON option allows copying the settings of all the maps you have added to the resource. You can transfer the copied settings to other resources using the Import from JSON button.
