# Introduction
A web coverage service (WCS) is provided for the gSSURGO and gNATGSO [map unit key grids](https://nrcs.app.box.com/v/soils/folder/180456387335). These grids represent a rasterizaion of the gSSURGO and gNATSGO map unit keys for the conterminous United States at a resolution of 30m, referenced to an Albers Equal Area Conic (NAD83) coordinate reference system (EPSG:5070). Grids are LZW compressed and internally tiled for efficient random access. Cell values are map unit keys, encoded as unsigned 32-bit integers. The grid topology and cell values are identical to the rasters contained within the gSSURGO and gNATSGO file geo-databases (FGDB). The GeoTiff format is used to ensure maximum compatibility. Files are re-created as part of the annual SSURGO refresh cycle.

An experimental WCS is provided for raster soil survey (RSS) products at 10m resolution.
