Hi there, We have been looking at the potential to produce animations in SMS. It looks as though the .h5 file format may have advantages over other dem files in how it can be displayed in SMS (eg, transparency, relief or hillshading, etc). If I am correct about the .h5 file (we have only been watching the SMS tutorials), does anyone know how to convert dem files (eg, Esri's ASCII grid file format) to .h5 format? Kind regards, Paul.
