"Contour Generation from DEM Data”

1. Launch Bentley Map

2. Create a New 3d File

3. Set up the Coordinate System Tools > Geographic> Select Geographic Coordinate System

4. Create a New Level – Example : 53 and color as 22  Settings > Levels> Manager.

5. Now you can attach and check the image you want to extract the Contours

6. The Raster DEM is attached as below :->

8. Assign a New STM layer for the extraction Process.

9. For the STM setting, we can turn the Contours on.

10. You can set the specification for the Major, Minor Contours and the Interval as required.

11. Add the DEM file as the STM Input to generate Contours.

13. Now You could able to Generate Contours out of your DEM data.
