gdal_interp.earth

<!--
osgEarth Sample : gdal_interp.earth

Shows the difference between all the available intepolation modes for the gdal driver.

Because the world.tif file is very slow resolution, we increase the max_data_level to force additional tiles to be generated
to show off the effect of the interpolation.

Run with osgearth_toc to see the differences in interpolation

Note, gdal image interpolation is only available if your GDAL version is 2.0 or higher.
