Terrain Datasource

A terrain data source can be added to a project in order to provide the necessary elevation information for the 3D visualization. This terrain data source can either be created with a Terrain Task or a Terrain Mesh in Mesh, or added manually from an external source.

If the data is added from an external source, it must be in the Quantized Mesh format to ensure that the terrain data is correctly interpreted and displayed. The URL then ends with a "/" (specifying layer.json is not required).

Option	Description
Name	Name of the Datasource.
Description	Description of the Datasource (optional).
Bounding Box	Describes the bounding box of the data. Clicking the button "Edit Bounding Box" opens a new map window where a bounding box can be defined interactively. Clicking the button "Draw new extent on map" activates the bounding box mode, allowing the user to define a bounding box by clicking twice on the map (e.g., top-right and bottom-left corners of the bounding box). The coordinates of the bounding box are automatically adopted in EPSG 4326. Clicking the button "CLOSE" closes the map window.

Bounding Box

Describes the bounding box of the data.
Clicking the button "Edit Bounding Box" opens a new map window where a bounding box can be defined interactively. Clicking the button "Draw new extent on map" activates the bounding box mode, allowing the user to define a bounding box by clicking twice on the map (e.g., top-right and bottom-left corners of the bounding box). The coordinates of the bounding box are automatically adopted in EPSG 4326.
Clicking the button "CLOSE" closes the map window.

URI of the datasource.

Request vertex normals

Option to query the vertex normals of the terrain. Vertex normals are required to enable correct lighting.

Request water mask

Option to query the water mask of the terrain. Water masks can be used for rendering water effects.

Data Preview

The data preview allows a visual check of the configured data source before publication. It displays the data in the map window using the selected projection and within the defined extent. Users can interactively pan and zoom the map to review the display.
Changes to the data source or the extent are applied to the preview after clicking “Reload Map.”
