GM_CreateCustomElevGridLayerEx |
Creates a new custom layer that represents an in-memory elevation grid. The handle to the newly created layer is returned. You must call GM_CloseLayer on the returned handle when you are done with it. If a problem occurs, NULL is returned for the layer handle.
The layer handle returned can be used just like any other layer handle. This means that you can do things like generate contours and calculate view sheds using the data.
