SSURGO data is only available from Web Soil Survey with a Geographic WGS 1984 coordinate system. Once the data has been downloaded, ‘SSURGO Management’ tools can be used to re-project the spatial data to other coordinate systems such as UTM (WGS 1984 or NAD 1983 datum only).
What resolution is NAIP?
1-meter
What spatial resolution is the imagery? NAIP imagery has a 1-meter ground sample distance (GSD). Beginning with the 2011 NAIP season, ½-meter GSD imagery is available through a contract “buy up” if the additional funding for the higher cost of the imagery is available from state or federal partners.

What is NAIP data used for?
The NAIP imagery is used to maintain Common Land Unit (CLU) boundaries and assist with farm programs. The goal of NAIP is to collect 1-meter imagery for the entire conterminous United States. The imagery is acquired as a 4- band product, which can be viewed as either a natural color or color infrared image.
How is NAIP collected?
NAIP imagery is acquired from aircraft using film or digital cameras that meet rigid calibration specifications. No film cameras were used for the 2010 NAIP acquisition. Digital sensors may use a continuous collection technology, or may use set “exposures,” similar to film based acquisition.
How often is NAIP imagery collected?
Generally, NAIP imagery is refreshed on a 3-year cycle with approximately one third of the continental U.S. flown each year. The month and year of imagery acquisition can be found in the “Info/Metadata” links in the product search.
