[Marble-devel] Elevation model

[Konrad Enzensberger]

Hi Niko,

after compiling new code i did some investigation
to new feature like ElevationModel, TreeCreator, ...

I like to ask some questions about.

Based on SRTM data files (hgt) you are creating image tiles,
those image pixel values are set accordingly to SRTM height value.
In ElevationProfilePlugin, for calculating a profile, the height values are 
extracted from the image pixel values.

What is the advantage to go this way ?
Why not simply reading the height value directly from the hgt files ?
Are this new image tiles additional used for some kind of blending like it 
is
done currently with the hillshading tiles?

br, konrad
