Alaska Statewide Digital Mapping Initiative
Program Goals• CREATE A BASE MAP OF ALASKA: Acquire imagery and
digital elevation data necessary to meet specifications, generate ortho-imagery and DEMs, and assess accuracy of final products.
CREATE THE ARCHIVE: Develop the project infrastructure to warehouse, archive and make products available to the public.
LIFECYCLE MANAGEMENT OF THE BASE MAP DATA: Provide ongoing management of the base map data.
Governance Model:MOU Signatories
• Department of Natural Resources• Department of Military & Veterans Affairs• University of Alaska • Department of Transportation & Public Facilities –
pending signature.
• Executive Team• Staff Implementation Team
Project Funding
• $33.3 Million Original Estimate$33.3 Million Original Estimate– 25% State Funding 75% Federal Funding25% State Funding 75% Federal Funding
• $2.0 Million State GF Funded in FY07$2.0 Million State GF Funded in FY07• $2.0 Million State GF Funded in FY08$2.0 Million State GF Funded in FY08• $2.0 Million State GF Funded in FY09$2.0 Million State GF Funded in FY09• $6.0 Million total $6.0 Million total • Balance $4 Million; Working with Federal Partners
through the Alaska Geographic Data Committee
Accomplishments
• Created a Mapping Portal at the University of Alaska for public imagery and elevation models; serving data to the public via open standards protocols: WMS, WFS, WCS, and KML and direct downloads. Growing number of users and contributors. (Goal #2; #3)www.alaskamapped.org
• Purchased Data Uplift Licenses to move single agency licenses to a shared public viewing license. Uplifts for Yukon-Kusko Delta, Cape Yagataga Coastal Areas, statewide Landsat Image. (Goal #1)
Accomplishments
• Support for Kenai Lidar Project : Invested $250,000 (~18% if project cost) with federal and borough partners; data acquired and products in development. (Goal #1)
• Planning Contract with HDR Inc. Charlie Barnwell, Project Manager. User input, existing inventory, management options, workshops, and data acquisition plans. About 60% complete. Next major steps, Imagery Workshop, Whitepaper, and RFP.
Accomplishments
• Completed an open-forum DEM Workshop in Anchorage, and published a whitepaper; lead author Dave Maune, Ph.D from Dewberry, Inc.See: www.alaskamapped.org
• Hosting an open forum Ortho-Imagery Workshop in Anchorage, March 2-3, and will publish a whitepaper, lead author by Russ Coward, I-Cubed.
•Testing ASTER DEM in partnership with Dewberry, UAF ASF, and USGS. (Goal #1)
Draft Specifications: ImageryReview at Ortho Workshop
• Statewide Specifications: – 1.0 to 2.5 meter Statewide– Ability to collect the state in 5 years or less, (leaf on,
10% cloud cover)– Multi-spectral optical/IR– Ability to refresh on a 3-5 year cycle and to monitor a
major event (fire, flood, earthquake etc.)– Support map production of 1:24,000 or larger, meeting
National Map Accuracy Standards.
Top Goal for Workshop: Consensus Statewide Orthoimagery Specification
Draft Specifications: Imagery Review at Ortho Workshop
• High Resolution Areas, Specifications: – Population Centers and Transportation – Utility
Corridors– 0.2 to 1.0 meter– Support map production of 1:8,000 or larger, meeting
National Map Accuracy Standards.– Project specific– Two or more-partner acquisition; lead by project
team’s business requirements with SDMI potentially as a supporting partner
• Estimates indicate about 10% of the state would require high-resolution coverage.
Draft Specifications: DEM From Whitepaper
• High Resolution Areas, Specifications: – 10 foot contour interval or less (e.g. Airborne LIDAR)– Engineering applications, detailed modeling, low slope
and relief areas
• Mid Resolution Areas, Specifications: – 20-30 foot contour interval (e.g. Airborne IFSAR)– Aviation Safety, covers large areas to statewide
• Low Resolution Areas, Specifications: – 40 foot contour interval or larger (e.g. Satellite)– Ortho-photo rectification, statewide coverage
Draft Specifications: Public Access
• Public Domain 1st choice (ideal)• Broad Use License with public access to
processed images 2nd choice (acceptable)• Central Core Storage – UAF-GINA• Decentralized Storage-Users & Mirror Sites• Live Access via OpenGIS Protocols• Partnership w/ Private Providers (e.g.
Google, Yahoo, MapQuest, Microsoft)
Draft General Schedule & Unknowns
• March 2009: Ortho Workshop• April – May 2009: Imagery RFP• May 2009: DEM IfSAR Recommendations to
Implement and Fund• June 2009: HDR & I-Cubed Contract WrapsUnknowns• Spring 2009: FY10 CIP decisions• Opportunities from Stimulus-Omnibus Bills
