It's a little hard to help you as long as long you neither provide details
about how you examine your app and its data, nor post the respective code.
Also a SSCCE (http://www.sscce.org/)
(E.g a sphere to mock the your earth globe, a cube to mock the text node, and a
plain toon shader that colorizes depending on magnitude of the respective coord
...)
would not be hard to assemble, or would it?
