- All SSURGO-based Living Atlas items upgraded to the 2017 SSURGO snapshot
- New map image and 21 image layers with improved performance
- New tile layer for use with the map image layer in web maps at small scales
- New downloader application – provides faster access to the attributes you need
The Soil Survey Geographic Database (SSURGO) produced by the Natural Resources Conservation Service (NRCS) provides a valuable resource with 36 million mapped soil units, dozens of attribute tables, and an extent that includes the 48 contiguous United States, Hawaii, portions of Alaska, Puerto Rico, the US Virgin Islands, and 6 US territories and associated states.
To complement these resources and help bring this powerful dataset to the ArcGIS platform Esri has created several information products that are available through the Living Atlas. For a quick review of available soil mapping resources see the Living Atlas for Soils story map.
Map image layer – USA Soils Map Units – What’s new?
- Improved performance
- Updated to 2017 data
- Increased Scale Range
- New Tile Layer
The USA Soils Map Units layer provides a map of approximately 36 million detailed polygons and over 150 useful attributes. It is preconfigured with a custom pop-up. The map service is combined with a tile layer in the USA Soils Map Unit web map resulting in a map that draws quickly across the full range of scales. A previous version of the USA Soil Survey is now in Mature Support, so please point all of your resources to the updated layers.
Imagery layers – What’s new?
- All 21 soil imagery layers updated to 2017 version of SSURGO
- Improved symbology and legends for many layers
- Multiple levels of classification added to USA Soils Farmland Class and USA Soils Hydric Class
- USA Crop Production updated to NCCPI v2.0
We have updated all 21 of our SSURGO-based imagery layers with 2017 data. These layers are ready to use in your analyses and can be used as inputs to geoprocessing tools, model builder and Python scripts. The Living Atlas for Soils story map provides an overview of the collection or you can navigate directly to the layers in the Living Atlas.
The imagery layers include Soil Hydrologic Group:
