Hy,
I'm afraid but I can't help you. But you can try r.soil.texture for your
area:
1. import in grass soils sample point with sand and clay atttributes;
2. interpolate sand a nd clay surface with one algorithm available in
grass (or with R interface for geostatistica analisys)
3. run r.soils.texture with your favorite scheme (USDA,ISSS,FAO) , sand
and clay grid and get your texture map;
I hope it's useful.
P.S. If your next san will named Gianluca we can make a vitualy drink!

Dear GianLuca
First of all, it is very curious, but I wife and me choose two
possible names for your (born) san. One was Gian Luca, and the other
was Camillo Cornetta (my wife's decendence is from Rovigo, Italy). But
the choosed name was Camillo. May be the next will be Gian Luca!
Back to the work, do you know where can I find a soil texture map for
Brazil ? I am looking for this kind of data for species distributio
modelling. Case you can help me, I will be very grateful.
Ciao,

Hy,
I've upgrade the module r.soils.texture with FAO and ISSS texture
scheme. You can define soil texture based on USDA, FAO and ISS
triangle, from sand and clay GRID. The module is availabre for
download from addons wiki .
I hope anibody try it.
Gianluca
