I may not have asked that question very well. The HDF-EOS Level 2b is an hdf4 file that contains point data and has a structure that is quite different from the Level 3 (which I have been able to bring in as a raster after using HEG to pull a specific object from the file). If anyone else has the same need, the contents can be pulled out of the point file using the hdp hdf dumper from the HDF Group (http://www.hdfgroup.org/hdp.html). In my case, I wanted a subset of the fields from a specific vdata node in the hdf structure. The command line I ended up with was hdp dumpvd -o AMSR_E_L2_Land_V09_200206190754_A.txt -d -i 1 -f Latitude,Longitude,Soil_Moisture AMSR_E_L2_Land_V09_200206190754_A.hdf -o ... = output file name -d = no headers -i 1 = the index of the vdata -f ... = the field names The produced a file that can be read as a table in R. http://hdfeos.org/software/tool.php#HEG is appropriate for Level 3 HDF to GeoTIFF http://www.hdfgroup.org/hdf-java-html/hdfview/ is good for exploring the file structure of many hdf forms Maybe this will be useful for someone.

Mark, have a look at: http://www.nceas.ucsb.edu/scicomp/usecases/ReadWriteESRIShapeFiles hope this helps, Rick Reeves On 6/25/2010 9:40 AM, Mark Connolly wrote:
I am trying to load point data into R, but am having no luck. Does rgdal support these data sets? Thanks, Mark Connolly Master of Science Program Department of Soil Science North Carolina State University PO Box 7619 Raleigh, North Carolina 27695-7619
