Create Simulation Layer

Instructions

The Create Simulation Layer function can be used to create the data source and corresponding dataset templates for flood simulation.

Before creating a simulation layer, you need to prepare the following data (all data must use EPSG:4490 coordinate system):

Raster dataset (required): Used as the base terrain for simulation analysis.
Optional data:
- Model dataset: Hydraulic structures or other buildings that affect the flood flow process (EPSG:4490).
- 3D polygon dataset: 3D polygon data specifying the flood simulation analysis area (EPSG:4490), containing only one polygon.

Flood Simulation tab -> Configure Simulation Layer group -> Create Simulation Layer button

Add the required raster dataset, model dataset, or 3D polygon dataset (EPSG:4490) for analysis to the scene.
Click the Flood Simulation tab -> Configure Simulation Layer group -> Create Simulation Layer button, and the "Create Flood Simulation Layer" dialog box will appear.
Set storage path: Click the Select button to the right of "Storage Path" and choose the save location for the target data source (*.udbx) in the selection dialog box.
Set file name: Set the name of the target data source. The default value is Datasource.
After setting, click the OK button. A new data source named with the specified name will be created in the workspace, containing the following datasets in EPSG:4490 coordinate system: Water Source Point Dataset, Obstacle Line Dataset, Waterway Line Dataset, Study Area Polygon Dataset, Node Dataset, Edge Element Line Dataset, Cell Line Dataset, Parameter Table Attribute Dataset. These datasets will be used for subsequent flood simulation analysis.

Notes:

Before creating a simulation layer, ensure that the base terrain raster dataset has been loaded into the current workspace.
The datasets used for simulation analysis must use the EPSG:4490 coordinate system; otherwise, it may affect the subsequent calculation unit division and simulation analysis results.
