Re: referencing the pixel values from the geotiff with soil classification data

[Tomislav Hengl]

Hi Travis,

We are working on making a better documentation for the data on FTP. In
the meanwhile please refer to this:

The Value-class tables you can also find here:

USDA classification
https://github.com/ISRICWorldSoil/SoilGrids250m/blob/master/grids/models/TAXOUSDA/TAXOUSDA_legend.csv

WRB classification
https://github.com/ISRICWorldSoil/SoilGrids250m/blob/master/grids/models/TAXNWRB/TAXNWRB_legend.csv

We have now also a new interface to browse all Geotifs via Geonetwork
see e.g.:

One of the projects that I'm involved with is the assessment of road disturbance and recovery in arid landscapes along the US/Mexico border and I believe that SoilGrids data may be useful for our project. I've downloaded geotiffs from SoilGrids.org for the purpose of uploading into Arcmap for analysis, but I've discovered that there is no attributable data as a part of the geotiff. I downloaded geotiffs of our study area of the following two types: 1) SoilGrids250m: TAXOUSDA: Predicted most probable class 2) SoilGrids250m: TAXNWRB: Predicted most probable class. I also can't find a way of referencing the pixel values from the geotiff with soil classification data. I'm clearly overlooking a step, can you please point me in the right direction.
