[R-sig-Geo] Early version of gdalUtils (GDAL Utility Wrappers) now on R-forge

[Jonathan Greenberg]

For MODIS users (which was, in many ways, the main reason to develop
this package -- Matteo is also one of the developers of the modis
package, incidentally), take a look at:
?get_subdatasets
for use with ?gdal_translate via the sd_index parameter (this is a
value-added parameter, not one that came with the command-line
gdal_translate).

I haven't tested these yet with HDF5 and NetCDF files but, in theory,
they should work since they use the same subdataset naming scheme
(SUBDATASET_n_NAME, where n is the value to pass to sd_index).

As a small note, as requested by a user who contacted me, I added
gdal_rasterize and gdaldem to the list of ported functions last night
(version 0.0.6 or later).  Again, if anyone has a GDAL function they'd
REALLY like to see ported ASAP, kick me an email -- it only takes
about 10-20 minutes to port/document each function at this point (we
wrote some helper functions to build the wrappers).  We'll eventually
get through all of them, but not in the next week.

We'd like to push the initial version to CRAN in a week or so, so let
us know ASAP if there are any bugs!  In particular, we'd really like
to know if our GDAL installation search tool is working (if you have
GDAL installed on your local system, this should search out the latest
version and use it, without you having to do anything).
