Hi, I was just at ESRI for a two-day meeting on multidimensional data access, time series support, and groundwater modeling, organized by David Maidment (CUAHSI and the University of Texas at Austin). Norm Jones from BYU gave a good presentation on his XMDF data model and format, built on top of HDF5 and aimed at supporting hydrology and the work being done by the Army Core of Engineers in ground water modeling. I gave a presentation on netCDF and discussed the netCDF/HDF project briefly. Other presentations covered ESRI plans for time and temporal processing, groundwater data models, hydro-geology models, and current status of 3D analyst tools. The ESRI developers I talked to seemed interested in building in direct access to netCDF and/or HDF5 data for their GIS tools rather than depending on a conversion program to store the data in a form they could already access. ESRI wants to support the atmospheric, climate, and ocean modelers as well as the hydrologists, and they would also like to be able to easily get weather data into their visualizations. It's still possible ESRI may decide something else is higher priority or the project is not practical for other reasons, but one of their most influential developers seemed optimistic about providing support for scientific data formats in the near future. --Russ
