Washington State's Opportunity to Participate in the National Agriculture Imagery Program
Statewide Ortho Imagery -
The State Program
Washington State agencies participate in a cooperative aerial photography mapping program that produces orthophoto data for much of the state of Washington. This means that cooperating state agencies are using the same base data for conducting regulatory, land management and planning work. This cooperative program will complete and deliver its first cycle of color orthophoto coverage in early 2006. A goal of the state of Washington program is to provide a consistent set of data over the entire geographic extent of the state. However, funding did not allow aerial photography to be collected on Federal lands or the Columbia Basin during this most recent cycle (Figure 1).
The Federal Program
The National Agriculture Imagery Program (NAIP), a cooperative program between Federal Agencies, provides orthophoto data of agricultural lands. The focus of the Federal program is to provide orthophoto imagery of agricultural lands to support Federal Ag and natural resource conservation programs. The major product of this program is a moderate (2 meter) resolution orthophoto that is produced and provided to crop compliance field staff within 30 days of the date of aerial photography (see blue map). The NAIP program is willing to expand its coverage from ag lands to statewide coverage and increase the resolution of its orthophoto product to one meter if additional funds can be obtained from cooperating states.
Orthophoto coverage provided by state of Washington program
NAIP plans to fly the state of Washington in 2006 and produce statewide coverage if organizations within the state agree to participate and provide additional funding. This is an opportunity for organizations in the state of Washington to obtain statewide orthophoto coverage collected in a single flying season.
The National Agriculture Imagery Program will collect ortho image data of the following specifications in 2006 if Washington agencies do not participate.
Coverage-Agricultural lands only (blue map)
Resolution-two meter pixel resolution
Imagery - true color
Accuracy five meter horizontal accuracy
Projection UTM zone appropriate (Zone 10 and Zone 11)
Cloud cover up to ten percent
Current Standard: Whitman Co. (at left) Agriculture lands; 2 meter image
Additional information about the NAIP program can be found at: www.apfo.usda.gov
Cooperatively Enhanced Specifications
Washington Geographic Information Council's (WAGIC) goal for this effort is to, as a minimum, acquire cooperative funding ($400,000) to expand the National Agriculture Image Program to include statewide coverage and an enhanced resolution from two meters to one meter. A secondary goal is to allow the acquisition of value added products for organizations that need and can fund these products ($800,000 total cooperative funding).
The National Agriculture Imagery Program will collect ortho image data to the following specifications in 2006 if Washington agencies do participate.
Basic Enhanced Specifications
($400,000 cooperative funding)
- Statewide orthophoto image coverage
- Resolution-one meter pixel resolution
- Imagery - true color
- Accuracy + - five meter horizontal accuracy
- Image products
- 1. Compressed county mosaicked file (MrSid 15:1compression)
- 2. Quarter quadrangle format tiff file with one meter resolution
- Projection UTM appropriate (Zone 10 and Zone 11)
- Cloud cover up to ten percent
Value Added Products
($800,000 cooperative funding)
- Projection State Plane Zone Appropriate, statewide south zone
- Resolution Resampled to state of Washington 3 foot pixel size
- Enhanced resolution - Half meter resolution
Cost to Participate and proposed schedule
To raise a total of $800,000+ in contributions from State, County, and Federal government organizations, before the end of December 2005. This level of contribution will provide statewide coverage and half meter resolution data.
