Hello all,

I am trying to generate raster stacks of soil layers from the WISE
database. To do that, I am trying to follow the script offered in:
http://spatial-analyst.net/wiki/index.php?title=Interpolation_of_ISRIC-WISE_international_soil_profile_data

However, in the long way to get there, I am unable to solve the following
problems:

1) I am not being able to make the RODBC work in a 64bit pc(win7). I went
to the R 64bit repository but it seems the version stored in it is still
the 32 bit version, once when installed it gives me the same error message
(=RODBC only works in 32bits computers).

2) When trying to do it in a 32 bit computer, I dont know how to transform
the two files (.rdc and .tif), coming from the zip file where the data are
stored, in an .asc file.
The script given in the page uses a function (

 fname <- zip.file.extract(file=paste(map.list[i], ".asc", sep=""),
  +    zipname=paste(map.list[i], ".zip", sep=""))

which does not work any more in R.

The parallel "unzip" command seems not have an option to specify the
extension of the output file when unzipping. so what I get is two files: a
.rdc and a .tif and i am having not memory power enough to even read the
.tif into R.

So, could anyone give me a hint on how to do it, either for 64 or for 32
bits ? Or any faster way to have a georeferenced stack of layers with that
soil database?

Thanks a lot!
Agus
