RUC/ETA BLIPMAPs. But that is not certain - the additional
resolution provided by RASP runs will _not_ provide significant
"added value" if the forecast accuracy is limited by factors _other_
than terrain resolution (e.g. such as limited "ground type"
resolution or initial humidity values). The RASP Sierra forecasts I
personally will be particularly interested in are the "convergence"
(BL Max Up/Down Motion) forecasts since the resolution of the
existing RUC/ETA BLIPMAPs is too small for good convergence
forecasts. The RASP forecasts are being provided primarily for
those pilots especially interested in weather and the mental puzzle
it provides - they may not be of value/interest to other pilots.

Are you using the SRTM-1 data for you base terrain data?
