Use this selector for defining the terrain area by giving the center position in XYZ and width, height in meters.

This format is good for small to medium size areas that are not correlated with real map.

 

Center of the terrain, in meters.

 

Use this button to manually recenter the terrain by selecting a new location on the map.

Window will hide, mouse cursor will change to +.

Click on the terrain map to get the new center position.

 

Width of the terrain (east - west), in meters, centered on origin.

 

Height of the terrain (north - south), in meters, centered on origin.

 

Use this selector for defining the terrain area by giving the two corner positions in XYZ. Width and height are automatically computed.

This format is good for small to medium size areas that shall be correlated with real map or position.

Specify in XYZ the coordinates of the bottom-left corner of the terrain (south-west).

 

Specify in XYZ the coordinates of the top-right corner of the terrain (north-east).

 

Use this selector for defining the terrain area by giving the center position in latitude, longitude and width, height in kilometers.

This format is good for big size areas that are correlated with real map.

 

Center of the terrain, in latitude, longitude.

Sometime, we need to setup a scenario around a known city, mostly when WebMap is intended to be used. Instead of zooming and panning inside the world map (which takes time as tiles must be downloaded from Internet), better to set the terrain directly around a given city, with a predefined area (width and height), then Apply and switch ON the WebMap layer.

vsTASKER knows 15000 cities of the world, so, it is likely you will find yours.

Enter the name of the city in the field then use the button.

If the city is found, it will be displayed in the Available Cities list (window below). If several cities exist under the same name, just select the one you want and click OK.

The coordinates of the selected city will replace the data of the Origin fields.

Apply and OK.

 

 

Width of the terrain (east - west), in kilometers, centered on origin.

 

Height of the terrain (north - south), in kilometers, centered on origin.

 

Use this selector for defining the terrain area by giving the two corner positions in latitude, longitude and altitude. Width and height are automatically computed.

This format is good for big size areas that shall be correlated with real map or position.

Specify in Lat-Lon the coordinates of the bottom-left corner of the terrain (south-west).

 

Specify in Lat-Lon the coordinates of the top-right corner of the terrain (north-east).

 

When set, earth curvature is used in line of sight computations by components and wherever it's needed.

From the code, use terrain->useEarthCurvature() to know if this option has been checked or not.

 

Import all definitions of the terrain, including all the layers definition (see formats), previously saved in /data/shared.

This reduce the time of a setup or when keeping the same database but changing the terrain setting.

 

Export all definitions of the terrain, including all the layers definition (see formats), in /data/shared.
