BoundaryAI (For Trial)

API for boundary retrieval. Currently based on the last publicly released 2008 Common Land Unit (CLU) boundaries are farm/field boundaries used by United States Department of Agriculture (USDA) in the delivery of certain farm programs.

It is not uncommon for more than one crop to be grown on a CLU. These CLU boundaries are derived from the last publicly available distribution from 2008. A single CLU is approximately interpreted as a “field”. A Common Land Unit (CLU) is the smallest unit of land that has a permanent, contiguous boundary, a common land cover and land management, a common owner and a common producer in agricultural land associated with USDA farm programs.

The Ag-Analytics Field Boundary API provides a service which a user can pass an extent (bounding box) and retrieve field boundaries in geojson. To our knowledge, this is the only CLU field boundary data service in the market. It is a frequently requested dataset and useful for researchers who seek pre-made field boundaries in order to conduct representative analyses, as well as other apps that wish to serve ‘starter’ field boundaries.

Request Parameters


Parameter Data Type Required? Default Options Description
geometry string Yes -- Spatial Coordinates (xmin, ymin, xmax, ymax, lat/long coordinates & wkid spatialReference) The geometry to apply as the spatial filter. The structure of the geometry is the same as the structure of the json/geojson
f string Yes -- geojson/json format Format of returned data

Response Parameters


Parameter Data Type Description
type String (GeoJSON Object) Describes the geojson object type (Point, Feature, FeatureCollection)
crs List Coordinate reference system (EPSG codes)
features List Container for all the features of the raster
features.id number Feature object common identifier
features.geometry GeoJSON feature object Represents spatially bounded points, curves, and surfaces in coordinate space (Polygon, Point, etc.)
features.properties List List of properties assigned to the spatially bounded feature (Here OBJECTID is the common identifier, CALCACRES is the acreage)
