Hi,
I am trying to read hdf4 files in R. I have tried to install the gdal

Hi List
I notice on the OGR formats page for ESRI Shapefile the following is
mentioned:
Size Issues
Geometry: The Shapefile format explicitly uses 32bit offsets and so
cannot go over 8GB (it actually uses 32bit offsets to 16bit words).
Hence, it is is not recommended to use
Darren,
These limitations are a result of the shapefile reader/writer
implementation. While the specification permits up to 8GB, the
implementation might not use it fully.
According to the specification a feature offset is stored as a 32-bit
integer to a 16-bit word. So, that's (2^32)*16 bits or
Forwarding to the list and others...

As Etienne told you, the geotransform and
fwtool is really old so you should not use it and uninstall it.
You may want to use the R package Rgdal, but I have not used iit under
windows.

I have a bunch of large GeoTiff files (1.4GB, 4 latitude degrees x 8
longitude degrees).
I need to slice each one up into 1 degree lat x 1 degree long tiles (with
just a little bit of overage in each).
Here is the gdalinfo output for one of the GeoTiff files:
Driver: GTiff/GeoTIFF

You can try merging them into a single OGR layer (with ogr2ogr for example)

Sorry my phone botched the reply. Meant to say having something like having
9 input files into gdalwarp and needing a cutline for each input to mask
their individual Nodata.

Thanks, that's exactly what I'm looking for.

Roger,
Thank you for the info and link. Using a modified version of your code I
was able to create and import into GRASS a GeoTIFF with the proper
georeferencing. The coordinate system units are in meters though, and I'd
prefer to have them in degrees lat/lon. Do you know if there's a way to

With shapelib or OGR ? With shapelib, you need to define SAOffset to be a 64bit
integer, which OGR does.
