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:

$2.0 Million State GF Funded in FY07
$2.0 Million State GF Funded in FY08
$2.0 Million State GF Funded in FY09
$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, UAFASF, and USGS. (Goal #1)
Draft Specifications: Imagery
Review 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)
