Simulation Area Settings

Instructions

After creating or opening a flood simulation data source, use the simulation area settings function to draw the effective area for flood simulation analysis.

Function Entry

  • Flood Simulation tab ->Configure Simulation Layer group ->Simulation Area Settings button

Operation Steps

  1. Click the Flood Simulation tab ->Configure Simulation Layer group ->Simulation Area Settings button.
  2. Move the mouse to the specified position in the scene, click the left button to start drawing the flood simulation analysis area; then move the mouse and click the left button in turn to determine the area boundaries, and finally click the right button to complete the drawing.
  3. After drawing, the system automatically saves the area to the "Study Area" polygon dataset and loads and displays it in the current scene.
  4. If there is an existing 3D polygon dataset representing the study area (coordinate system is EPSG:4490), you can directly open that dataset in the workspace and skip the above drawing steps.
Notice:
  • The simulation area is used to define the extent of the flood simulation analysis. It is recommended to draw a closed area.
  • When using an existing 3D polygon dataset as the study area, ensure that the dataset uses the EPSG:4490 coordinate system.
