For WebGL and Offline, it is now possible to upload a shape file that defines a terrain modification in a layer.
The Shape file
The Shape file has to be defined in the same coordinate system as your background data. The shape can consist of one or several polygons that each can have different height modification settings.
Here’s an example of a shape file that has one polygon and height and color attribute which will be used for the terrain modification.
Create a new layer or modify an existing layer. In “Scenery modification”, click the “Upload shape file” button and select your file.
After upload, you can customize terrain height, surface color and opacity. Terrain height is defined relative from absolute zero altitude. You can type in a value manually for all surfaces or use a value from a linked attribute defined for each surface geometry in the Shape file. Color can be set manually for all surfaces or mapped from a linked attribute per surface.
Note: The terrain modification will not be visible in the Java editor, you have to switch to the webgl project view to see the result.
