These notes may be more appropriate in some other BiGCZ repository rather than CZIMEA, but this is a good place to start.
A general warning / caution about many soil data compilations: soil profile location (lat-lon) are not always highly accurate, or even present at all. eg, in a review of the WoSIS paper, it was stated that "In the current version of WoSIS, about 20% of the soil profiles do not have a quantitative georeference, i.e. numeric geographic coordinates". The ISCN documentation makes similar warnings, while highlighting the value of data that has many consistent parameters at one profile/horizon even though it doesn't have good (or any) lat-lon locations.
- As available primarily from CZOCentral WOF
- Data structure is highly variable, but this is a resource that must be assessed. Luquillo CZO would be a great place to start.
- See ModelMyWatershed efforts. Anthony can fill in details on this.

- He even studies the "Sierra Foothill Region of California" and lives in that area, so may be of direct interest to Emma and the Southern Sierra CZO
- eg, this older reference: Kern, J. 1995, Geographic patterns of soil water-holding capacity in the contiguous United States. Soil Science Society of America Journal 59, 1126-1133. Can then look up recent studies that cite it in building newer, better, broader US datasets
- In coordination with BiGCZ goals, it'd be good to try to ingest/map some data from ICSN into ODM2. That'd benefit both CZIMEA and BiGCZ in multiple ways.
- Jennifer (Jen) Harden 82soiljen@gmail.com is the new lead; Deb Agarwal DAAgarwal@lbl.gov is or was a technical data lead. Margaret Torn (no longer the lead) also mentioned Chris Swanston cswanston@fs.fed.us as being involved
- "Now in its 3rd generation (12/2015), the ISCN database includes data for over 430,000 individual soil layers from over 71,000 profiles worldwide."

- Has working GeoServer instance, with OGC (WMS, WFS, etc) access to all the data! I've already tested it successfully with QGIS.
- This looks like a fantastic resource

- SoilGrids250m:
- All data are downloadable as geotiffs. Also available via GeoServer application, and "For accessing SoilGrids at point locations please refer to http://rest.soilgrids.org documentation"
- Very nice interactive map application
- Not a dataset, but a set of software tools in R, plus the collaborators involved. It's described as the "ISRIC Cyberinfrastructure" for global soils work. See the GSIF section in the SoilsGrids1km paper
- Looks like it's mainly the group that's developing WoSIS and SoilsGrids1km, but also have links to Dylan Beaudette (USDA-NRCS)?!
- Are running a "Spring school: 15 – 19 May 2017." Looks great!

- How is this related to SoilsGrids1km (above)? Both are from ISRIC, same group.
- Quite ambitious. But, web site looks highly dated and stale, hence I'm suspicious about its current status ...
