[mapserver-users] MapServer and NetCDF with date-time

[Mark Jackson]

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
Mark
