SSURGO Soil (Trial)

The SSURGO Soils API provides soil type and average of the soil type attribute (e.g., NCCPI) by field for a shape entered.

This API is utilized to drive the Ag-Analytics SSURGO soil panel below, for illustration. Area calculations from the API are provided in square meters and can be easily converted to acres on the front-end. The API Response contains shapes/features in ESRI JSON format, as well as the calculated metric (e.g., National Commodity Crop Productivity Index) and areas of each shape, the soil type name, the area for the sums of each soil type across all features for display in the table, metadata related to projection and other information. This API can be easily called and mapped using any standard front-end JavaScript mapping library (e.g., Leaflet).

Request body

inputShape (ESRI Polygon shape): The inputShape should have the Albers (“wkid”: 5070) spatial reference. The shape information for field is esriGeometryPolygon format. Standard open source JavaScript front-end libraries (e.g., Leaflet) can be used to structure the shape. See example request below, in which "spatialReference": {"wkid": 5070} is required
inputFields (string): The metrics to return with the format “TableName_SoilTypeName”
