Terrain in Terrain Datasource

Visual representations of Terrain in Terrain Datasources are used for visually inspecting the calculation results of the terrain converter. The following table provides an overview of the options.

Terrain in terrain representations can also be created manually if they were generated using the VC QMesh converter, e.g., by a local, external process outside of the VC Publisher.

Terrain in terrain representations cannot be used in the final application! For the final, public application, the terrain in terrain dataset must be integrated into the base terrain and the new base terrain must be published. Terrain in terrain representations are solely for visually inspecting the calculation results of the terrain converter.

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

URI of the datasource.

Base terrain

Selection of a base terrain that serves as the foundation for the terrain in terrain representation. Any terrain data source available in the project can be selected.

Apply update

Integrates the smaller update terrain into the base terrain. The terrain in terrain dataset is deleted and integrated into the base terrain. This button starts a job that integrates the terrain in terrain data source into the selected base terrain. Updating a base terrain is always important when more than one dataset needs to be integrated into the base terrain and when the result needs to be displayed in a public map.
CAUTION: This action cannot be undone.

Use vertex normals

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

Use water masks

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

If warning messages are displayed, the terrain in terrain calculation should be performed again before applying the update to avoid errors. Error messages may look like this: "The base terrain dataset was changed in another process. You may need to recalculate the terrain in terrain."

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.”
