Hi
Does anyone have any advice on the best way to serve NetCDF floating point
rasters with a date-time dimension?
I want to use MapServer to serve up WMS, WMS-T and WCS from NetCDF 3 and
NetCDF 4. The NetCDF files will be compliant with the CF conventions and
will contain lat, long and date-time with floating-point raster data.
Would MapServer / GDAL support this? I've seen that GDAL supports NetCDF
but it's unclear whether it supports NetCDF 4 and I can't see any mention
of whether it supports WMS-T. Presumably it would need to treat the
date-time data like a tile index. Maybe GDAL could read the NetCDF and
create a tile index for MapServer (in PostGIS?).
I've also found a project which did something very similar called ADAGUC.
These guys wrote their own GDAL driver for NetCDF 4 with lat,long,date-time
and patched MapServer. Would that still be the best approach now? This PDF
describes what they did. I may also contact them directly.

Does anyone have any advice?
Thanks in advance
