Dear GrADS Users,
We have started uploading to sf.net sources and binaries for the OpenGrADS
Bundle based on COLA's *2.0.a8* release:
https://sourceforge.net/projects/opengrads/files/
Look under *grads2/2.0.a8.oga.1*
The OpenGrADS Bundle is a new way of packaging GrADS builds that is somewhat
inspired by my experience with the Win32 Superpacks. The idea is to have a
single package that require no (minimum?) configuration and that is easily
relocatable (say to a USB memory stick). The structure of an OpenGrADS
Bundle is described here:
http://opengrads.org/wiki/index.php?title=The_OpenGrADS_Bundle
Once you download the tarball take a look at the INSTALL file. You can
install it as a Bundle (highly recommended) or simply install the binaries
the same way you did in the past.
If you would like to build it from sources notice that the OpenGrADS Bundle
2.0.a8 requires *Supplibs v2.2.0* available from:
https://sourceforge.net/downloads/opengrads/supplibs/2.2.0/
The Windows build will be available soon, for now only Mac OS X, Linux,
FreeBSD and AIX.
*Note for Mac OS X users: *
** Unless I hear from you, I am not intending to post a PowerPC build.
Let me know if you would need a PPC build of the OpenGrADS Bundle.
This OpenGrADS release has improvements in the LATS interface and in several
of Mike Fiorino's extensions. We are also deprecating the SHAPEFILE
extension as this functionality is now built in GrADS. See the
included "Documentation.html" for an in-depth description of the OpenGrADS
extensions. See below for additional information on this release.

Cheers!

GrADS Version 2.0.a8
Released 10 July 2010
This OpenGrADS version is based on COLA's 2.0.a8 release which has
many new features, including several that were required to support
COLA's work with extremely high resolution data sets.
COLA's GrADS version 2.0.a8 is now linked with netCDF-4, which
supports compressed netCDF files and also has a new OPeNDAP interface
for gridded data sets. (This feature had already been included in all
OpenGrADS releases since 2.0.a2.) The netCDF-4 support by COLA
includes new commands (q cache, q cachesf, set cachesf, set
chunksize), new options to 'set sdfwrite' (-nc3/-nc4, -chunk, -zip,
-flt/-dbl), and a new descriptor file entry: CACHESIZE. Please begin
by reading the User's Guide page entitled "Reading and Writing
Compressed Data Sets" at
http://iges.org/grads/gadoc/compression.html.
A side benefit to the netCDF-4 development was that it led to an
improvement in the HDF5 interface, which is now significantly faster
than in the previous release.
GrADS version 2.0.a8 also supports reading and drawing shapefiles, and
the OpenGrADS SHAPE extension is being discontinued. The shapefile
interface is adapted from an original design by Graziano Giuliani, the
same code used for developing the OpenGrADS SHAPE extension. There are
several new commands: 'draw shp', 'q shp', 'q dbf', and 'set shpopts',
and a User's Guide page entitled "Drawing and Querying the Contents of
a Shapefile" at http://iges.org/grads/gadoc/shapefiles.html .
COLA's work with extremely high resolution data sets led to a bunch of
changes to the GRIB interface. We added support for GRIB1 and GRIB2
files that are greater than 2Gb. This is handled with a "-big" option
to gribmap. A simple change to the user interface, but a fairly
significant change to code "under the hood." The gribmap utility now
also supports the "-b" option for GRIB2 data sets, a option that is
required for the new CFS Reanalysis. Both gribmap and wgrib have been
modified to support ECMWF grib files that have record lengths bigger
than 8MB.
There is a new graphics output option that is useful for the
interactive display of high-resolution data: 'set gxout imap'. This
quickly draws shaded grid boxes just like 'gxout grfill', but the
metafile is not updated so printim and print will not work. But it
saves a lot of time when browsing through data and 'fishing' for
something interesting to look at.
Two final miscellaneous items in the new release:
* Added template substitution strings %t4, %t5, %t6, %tm4, %tm5, %tm6
* New command 'q contours' returns contour colors and levels
This OpenGrADS release has improvements in the LATS interface and in
several of Mike Fiorino's extensions. See the included
"Documentation.html" for an in-depth description of these new
extensions.
Several other important OpenGrADS additions are available with this version:
- grads is now built with NetCDF v4.1.1 which includes support
for NetCDF-4/HDF-5 (similar to gradsnc4 in v1.9.0-rc1) and has
built in OPeNDAP support.
- this is an OpenGrADS Bundle release, a relocatable, minimum
configuration package that has all that you need to run GrADS. See
INSTALL for additonal information.
- we have introduced option -C to enable colorized text
- preview release of the OpenGrADS Extensions; the same extensions
available in GrADS v1.9.0-rc1 are now available with GrADS v2.0.
Caveat: as COLA is yet to publish the official API for User Defined
functions in GrADS v2.0 we have adopted here an API that
is based on our work vith v1.9.0-rc1. This is a very low-level
API that is *not* endorsed by COLA. As such, it is *not*
advisable
that users adopt this API to write their own extensions.
- These extensions are still being fully tested. Please report any problems
you encounter. Use them at your own risk.
- The following extensions are included: see below.
