Create Simulation Layer

Usage Instructions

The Create Simulation Layer function can be used to create a datasource and corresponding dataset templates for flood simulation.

The following data must be prepared before creating a simulation layer (All data must use the EPSG:4490 coordinate system):

Raster Dataset (Required): Serves as the base terrain for simulation analysis.
Optional Data:
- Model Dataset: Hydraulic structures or other buildings that affect the flood flow process (EPSG Code:4490).
- 3D Polygon Dataset: 3D polygon data specifying the flood simulation analysis area (EPSG Code:4090), containing only one polygon feature.

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. The "Create Flood Simulation Layer" dialog box pops up.
Simulation Type Setting: In the pop-up dialog box, select the simulation type, including Default Scene and Rainfall Preset Scene.
- Default Scene: When selecting this type, all parameters adopt default settings.
- Rainfall Preset Scene: When selecting this type, the rainfall rate in the simulation parameter configuration is preset to 40mm/h, and other parameters adopt default settings.
File Path Setting: Click the Select button on the right of "File Path", and choose the save location for the target datasource (*.udbx) in the pop-up selection dialog box.
File Name Setting: Set the name of the target datasource. The default value is Datasource.
After the settings are complete, click OK. A new datasource named with the specified name will be created in the workspace. It contains the following datasets in EPSG:4490 coordinate system: Water Source Point Dataset, Barrier Line Dataset, Waterway Line Dataset, Study Area Polygon Dataset, Node Dataset, Edge Element Line Dataset, Cell Line Dataset, and Parameter Table Attribute Table Dataset. These datasets will be used for subsequent flood simulation analysis.
