Slide 2 - Build Terrain By Hand

This exercise teaches you how to build a simple georeferenced mesh.

Build The Mesh

The mesh extents now correspond to an area on the Earth but they are still unprojected. In fact the mesh is only 1 unit across.

  1. Examine the hierarchy: This is a picture of the hierarchy.
  2. Right click over the mesh node named NewMeshNode and select Modifiers » GeographicProjectionModifier from the listed options.
  3. If you can see the mesh on the worksheet, it disappears.
  4. Double click the GeographicProjectionModifier.
  5. This displays modifier properties in the property editor.
  6. Set Projection to Universal Transverse Mercator.
  7. Double click the GeographicProjectionModifier again. The property sheet changes.
  8. Set UTM Zone to 13.
    If you're wondering how we knew the correct UTM zone, right click on the RectangleGeometryModifier and select GIS » Display UTM Zone from the listed options.
  9. Examine the hierarchy.
  10. Right click over the light node named AmbientLight: 1,1,1 and select Set Light Infinite from the listed options.
  11. Examine the hierarchy and left click the mesh node named NewMeshNode.
  12. Left click the worksheet and select Worksheet » Camera » Find Terrain from the listed options.
  13. Left click the worksheet and select Worksheet » Camera » Top from the listed options.
  14. The worksheet looks like this: This is a picture of the worksheet.
    Scenome also supports Lambert Conformal Conic and Robinson Projections. In addition to those projections, Scenome supports a variety of spheroid models but that greatly exceeds the scope of this documentation.
  15. That concludes this exercise.
