Hi  -

My group is trying to run SLAMM in Belize.
We only have the ASTER GDEMv2, a global DEM.
It may be that the vertical accuracy is too coarse, however the system is primarily mangroves, so there are not that many habitat conversions that we need to be able to capture.

In any case, we are having trouble converting the vertical datum from EGM96 to NAVD88.
I know this is a long shot, but does the model have the capacity to be run using a DEM with a datum other than NAVD88, and the corresponding VDatum correction?
(Alternatively, if anyone has had success converting between those two datums, tips would be greatly appreciated - I think the NOAA VDatum conversion program only works in the USA).

Thanks,  Jess

We would like to run SLAMM at a site where we only have a 30m DEM. 
Before we do, however, we would like to know how coarse is 'too coarse' a DEM to run SLAMM successfully. 
We are aware of the elevation pre-processor for poor quality DEM.

Thanks,

Jess
