I understand. If I can't work around this, I'll end up building gdal
the way I need it, and then the rest on top of it, but (hopefully) I
shouldn't have to go that far. I'm new to GIS data, so I'm still
getting used to the technology stack. There's so much to learn!
Thanks again for the info.

Mike,
GDAL is a hard one in the sense that there are too many things you
can and can't compile into it. I don't think there is any packaged
distribution of PostGIS (even Linux/Unix) that can claim they
support all the available GDAL drivers. I could be wrong. They
probably don't support a lot of the proprietary ones that require
signing NDAs to download the SDK at any rate.
The only other thing we don't package is SFCGAL which we are
planning to package as part of PostGIS 2.2. Again I don't think any
Linux/Unix PostGIS distributions package SFCGAL at this point.
Thanks,
Regina

Regina,
Thanks for the feedback. At least I know I understood the problem
correctly. I'll try converting the data as you suggest, or teasing
it with SciPy, at least until I can move the project onto a Linux box.
Is there a list of any other differences between the full PostGIS,
and what's in the Win executables? That would be good info to have.
Thanks again!

Mike,
You are correct the PostGIS windows GDAL lib for raster support
(which includes raster2pgsql) is not built with netcdf support. We
built it to not require extra dependencies beyond what gdal includes,
what you could do is use MS4W
or
<http://www.gisinternals.com/sdk/>http://www.gisinternals.com/sdk/
and use gdal_translate to convert to a supported format. Though
this may not be an option depending on what you want to read from it.
I recall trying once to build in with netcdf and ran into issues
(mostly with additional dependencies required like hdf this
that) so put it aside as a non-trivial bit of effort to include that.
If there is enough interest and people are willing to subsidize our
effort, we'd be willing to put in the work to add it and maintain
it as part of PostGIS windows distribution.
Thanks,

Subject: [postgis-users] raster2pgsql, netcdf, and windows
Hi all,
I'm new to PostGIS, so I apologize in advance if this has been
asked and answered, or if this the wrong place.
I've just installed Postgres 9.3 on Windows 8.1 from pre-built
binaries, and had installed PostGIS 2.1.1 via Stack Builder . I'm
trying to use raster2pgsql on a netcdf file. Does anyone know if
this is supported on Windows? All I get is "unable to read raster file".
raster2pgsql -G yields a long list with nothing that looks like
netcdf. From what I've able to gather from the docs, there's some
underlying dependency with GDAL stuff. But on Windows, installing
from pre-built binaries, there's no separate gdal toolkit I can
see. I believe it's all already baked into the distributed
executable. If I need to alter the underlying tools, or rebuild
with a netcdf library, I'm not sure how I'd go about that. I can
probably build from sources if I have to, but I'd really rather not
go down that rabbit hole.
I tried reinstalling PostGIS from the latest dev binary
distribution, but there's no difference.
I was able to install MS4W, which includes a version of gdal tools
for Windows, and, using that, I can read the netcdf metadata, so I
know the file itself is good.
Does anyone know how I can get raster2pgsql to recognize it? Did I
miss a step, or is this just not possible on Windows?
Any suggestions, or pointers to additional info would be a big help!
Thanks,
Mike
