NAIP (National Agriculture Imagery Program) Imagery

naip

The National Agriculture Imagery Program (NAIP) is a program to acquire peak growing season “leaf on” imagery, and deliver this imagery to USDA County Service Centers, in order to maintain the common land unit (CLU) boundaries and assist with farm programs.

This data is different from our LARIAC imagery because it contains a 4th band – Near Infrared, which enables many powerful raster analyses to be completed, including vegetation mapping and carbon content sequestration, among others.

Data Access

This data is too large for download.  For Los Angeles County, we have loaded the 2014 NAIP data as provided by the Will Patterson from State of California Department of Fish and Game.  The State of California also hosts this data as map services that provide a wealth of information, including multiple years and multiple bands and derived data (e.g. NDVI).  These are packaged as layer files:

Supporting Documents

Here are a couple of documents to help understand NAIP better.

Background

The goal of NAIP is to collect 1 meter imagery for the entire conterminous United States. The imagery is either natural color or “four band” imagery, and is delivered in the year of acquisition.

NAIP imagery is acquired annually with the total coverage being determined by available funds from FSA and funding partners, considering FSA priorities. The NAIP acquires digital ortho imagery during the agricultural growing seasons in the contiguous U.S (lower 48 states). The NAIP provides 1-meter ground sample distance (GSD) ortho imagery or optional (with partner buy-up) 1/2-meter GSD ortho imagery, with a horizontal accuracy of +/- 6 meters to true ground. The data deliverables consist of DOQQ tiles and Compressed County Mosaics formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83). The NAIP imagery may contain as much as 10% cloud cover per tile. NAIP imagery is generally acquired in projects covering full states, and is typically available for distribution within 60 days of the end of a flying season. It is intended to provide current information of agricultural conditions in support of USDA farm programs. It is also used by federal cost share partners to meet their mission needs. The 2015-2016 Planned Acquisition Map shown here may change depending on funding.
