Digital soil maps of sand, silt and clay percentage mean and standard deviation indicate model variability and prediction uncertainty.
A validation dataset produced estimates of error for the predicted maps of sand, silt and clay contents at root mean of squared error values of 8.4%, 7.8%and2.3%3%, respectively, which is satisfactory in a practical context.

Mapping of clay, sand, OM and iron oxides using Landsat 5 products can strongly enhance agriculture management approaches.
In a visit to the Mikisew Cree First Nation's Government and Industry Relations Committee, we saw a map of tar sands leases granted so far by the Alberta government.
Of course, it was of Indian design, knitted, with all sorts of jagged lines, sectioned like a map in different colors of sand and rust and aqua.
I love the compositions of Won Kar Wai, the stories of Pan Nanlin, the dreams of Kurosawa, and Parajanov, the sublime eye of Massao, the visual poetry of Iturbide, the tenacity of Abramovic, the creation stories of the people in the Amazon, the sand maps of the Dine, the bittersweet laughs of my family in the Andean mountains, it could go on but I'll narrow it down to this.
The method is useful to map the three-dimensional distribution of sand ridges and underground saline water.
"Wherever the rover's been we can literally map down to the scale of sand grains," says Calef. "Although," he admits, "it takes a little bit of work".
