Terrain in Terrain Task

The Terrain in Terrain Task integrates a higher-resolution terrain into a lower-resolution terrain. The Terrain in Terrain task is almost identical in configuration to the regular Terrain Task. However, the tasks differ in that, in the Terrain in Terrain task, the user must additionally select a 'base dataset'.

The base dataset must be a Cesium Quantized Mesh and should spatially encompass the new data to be processed. It is also assumed that the base terrain has a lower or equal resolution compared to the dataset to be calculated in the "Terrain in Terrain" task.

The result of the Terrain in Terrain task is a new Mesh in Mesh data source, which references the base data source. When displayed in the data preview, the two datasets appear as a seamless terrain dataset. However, the two datasets (base dataset and updated terrain model) should be merged before publishing. Please read this section if you plan to insert a Terrain in Terrain dataset into the base terrain. Terrain in Terrain is the option of choice if several areas are to be integrated into a base terrain. However, these must be spatially separated so that the data can be processed in a Terrain in Terrain task, and the process must be carried out iteratively. This means that after calculating a Terrain in Terrain dataset, it must be used as the base dataset for calculating the next Terrain in Terrain dataset before the next dataset can be calculated and integrated.

To create a Terrain in Terrain task, the "Terrain" task must be selected and the "Terrain in Terrain Integration" option activated. A new field will then appear where the base dataset can be selected. All other settings are identical to a regular Terrain Task.

In addition to the settings of a regular Terrain Task, the Terrain in Terrain Task has the following additional settings in step 3:
