Contour lines - elevation slopes #408

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What should this feature enhancement do?

Like the geodesic grid, could an option be natively implemeted to draw
contour lines of elevation ?..

.. Because GE is great for retrieving data from SRTM database.

Are there any known workarounds that produce the similar results?

That is the question i was wondering about since some weeks while
developing a tiny DEM-like app ...

Our team has tried to implement contour lines as kml and it has been difficult. 
We often end up with complex 
layers that slow down the plugin considerably due to the amount of detail. So 
it would be great if the plugin 
supported this natively not only so we don't have to go through that trouble, 
but also for performance reasons.

NASA Worldwind does this job so easily that I still wonder why it's not 
implemented 
in GE.

By the way, there are two workarounds to draw "filled contour lines" :
1. With an Image GroundOverlay combined with a slider to change its altitude ...
2. Draw a rectangle with an equal & variable altitude (sort of satellite-like 
object)
