Hi Jon,

The 32-bit to 64-bit floating number conversion is flawed. As a modeler, it’s not an acceptable operation, and could lead to other issues. For displaying elevations, it’s probably not critical, but an annoyance in WMS. Although, it would be nice to avoid all those user questions, and not have to explain the inconsistency and conversion issue again and again.

Hi Tim:

sorry, its not obvious to me why the noise in the low bits is a problem.
