Projections for gridded precipitation

[zisis]

Hello,

I'm trying to set up a distributed model in HEC-HMS for a catchment area in Greece, aiming to couple it with gridded precipitation from numerical weather forecast models. While trying to set up the ModClark files in GeoHMS I can see it only supports the HRAP and SHG projections (not applicable in Europe).

I'd be grateful if you could provide some feedback on how to use different projections in GeoHMS. Unless HEC-HMS can't be used for distributed modelling outside the US. One last thing: any alternative to ascii2grid for ascii import to DSS?

Thank you in advance.
