Welcome - Introduction to SDMI & Welcome - Introduction to SDMI & Goals for the Workshop Goals for the Workshop

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.

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)
