AGDC General Membership Meeting
December 7, 2006

Proposed New AGDC Subcommittees - Contact Carl Markon or Rich McMahon to join

• AGDC LiDAR/IFSAR Subcommittee – National LiDAR Initiative meeting will be held at USGS in Reston, VA, in February 2007, Carl Markon will attend
• AGDC Control Subcommittee
  • Seem to be several initiatives going on simultaneously so there is a need to coordinate with each other
  • Need all agencies to speak with one voice to National Geospatial-Intelligence Agency (NGA)
  • Evaluate potential for using National Technical Means (NTM) data for Alaska
  • Gust Panos volunteered Chris Noyles from BLM to investigate
  • Need to contribute to the same database
  • State has village profile control that is very difficult to use
    • AutoCAD drawings difficult to link to the control
  • APFO has set up way to library image chips and control
    • Dave Davidson, USDA may be asked to join an upcoming call
• AGDC Subcommittee License Group
  • Copy of license agreement sent out by Lynette Nakazawa, BLM
• Business case study could replace the 2000 Alaska Digital Orthoimagery Initiative
• Potential AGDC Shoreline Subcommittee
  • Multiple shorelines need to be identified, documented and put in one place, i.e. low water, mean low water, etc.
  • Coast Guard has a very dated “official” total coastline mileage
  • Should subcommittee have representation from Coast Guard?

Tom Heinrichs, University of Alaska Fairbanks
Data Serving Model – Geographic Information Network for Alaska (GINA)

• Alaska Statewide Imagery Initiative imagery acquisition possible repository
• Inventory, identify needs, strategic planning
• Serve, manage licensing, web services
• Acquire
  • Uplift licenses, leveraged programs, coordinate new acquisitions
• Statewide Mapping Data System Interoperability Architecture
• Lightweight imagery viewer that allows user to build maps with downloadable imagery in readily usable format.
• RAW files
• Test version will be up in the next month or so, Tom will send out notice to test system.
  • Contact Tom to volunteer
• Licensing agreements
  • If on license you can get the data, other users are limited to a degraded version that cannot be “reengineered”
  • Customers will have “licensing account” to identify which licensing level can be distributed.
  • Seeking larger partnerships for licensing, complications with serving on web, in addition, Google Earth agreement with Digital Globe complicates serving DG imagery.

Ted Cox, USDA NRCS - Data Acquisition and Future Plans

• 1996 - 1 meter digital orthoimagery (DOQ) acquired; Kenai Peninsula, Anchorage, Fairbanks
• 2004
  • ADS 40 cameras through APFO NW Geomatics
  • Digital Globe has license restrictions
• 2006 Aerial Photography Field Office (APFO), Salt Lake City, UT IDIQ $23 per sq km, public domain
  • Aerometrics, conventional 40K film scans
• 2006 IDIQ is available for partners. DOQ deliverable, may also get imagery, film only, AeroMetric is the contractor.
• Ted is going to continue using the APFO for future work rather than doing their own contracts, APFO plans service contracts and performs QA/QC
• 2006 Titan contact $22 sq km.
• 2006 IKONOS through Titan to deliver FAS inventory site orthos, however, these site locations are confidential
• 2006 52 villages to be acquired by Digital Globe, with ground control collected by contract, these sites can be web-served
• 2006 villages from Digital Globe archive
• License requirements vary depending on product, contract, some can be served, some have limited share ability, some are confidential

Peter Parker, State of Alaska Department of Natural Resources - Alaska Mapper Demo

  Bandwidth and server resources are an issue

Paul Kimsey, USGS, Denver, CO – National Hydrography Dataset (NHD) Data Maintenance and Stewardship

• USGS is looking at a partnership stewardship approach to maintain and update the NHD for Alaska.
• NHD is statewide, 136 sub-basins (no source data for 3 sub-basins)
• Distribution backlog from sub-basin maintenance in 2004 and 2005
• By the end of this year USGS plans to have full coverage of Alaska available.
• St. Croix Pilot Project along the Maine/New Brunswick, Canada is working on the “edge match” with regards to shared sub-basins across the US/Canada border and if successful, this could be applied to the Alaska/Canada border
• USGS stewardship is a state-by-state distributed maintenance effort
  • Desire to identify a primary steward for Alaska who would be single point of contact for the data maintenance contributors throughout the State
  • Point-Of-Contact coordinates maintenance each State
  • Carl Markon is USGS Geospatial Liaison for Alaska
  • Memorandum of Understanding (MOU) will be developed to establish agreements among primary land management agencies
    • Assigns primary steward
    • USGS provides maintenance tools and training.
      • NHD GeoEdit Tool is a Forest Service tool developed through ESRI that USGS will be taking over in January.
    • Partners do own updates as they are most knowledgeable regarding changes in each sub-basin in their area of expertise, i.e. land management responsibility
    • Work with each States to include their hydrologic models
    • No financial commitment in MOU, work share agreements utilized
  • Technical issue where streams cross inter-tidal zones (areas of high tides like southeast Alaska) where the software pushed the shoreline to low tide in order to encompass the “reach”
  • NHD is as old as 50-years as it is based off the USGS topographic maps which are the “best data available” data source statewide
  • NHD Edit Tools demonstration Friday, December 8 at the USGS in Anchorage to demo the tools and discuss hydrologic and stewardship issues

Dennis Tol, BLM Alaska State Office – AGDC Hydrography Subcommittee Chair

• Working on correction of NHD errors along with QA/QC of the data
• 4^th level hydrologic codes being taken to 5^th and 6^th level (AWSHED Project)
• Watershed delineation finished to 5^th and 6^th levels, doing quality checks and will be submitted to National data set, some are larger or smaller than standard
• Geographic feature names will not be accepted upon upload into the national data base if they do not exist in the official GNIS
• Whereas the sub-basins will be available by the end of the year, not all will be edited, 71 sub-basins maintenance completed, 62 other ready for maintenance but lacking funds for contractor, may get 2007 funds for maintenance through USGS
• Editing work consists of editing for names, missing reaches, edge-matching, alignment (contour stream miss-matching)
• Many agencies are contributing funds for the BLM effort, no overhead is charged to these funds
• AWSHED Project can be viewed at http://agdc.usgs.gov/hydro
• Contact information for Dennis, phone (907) 271-3348, email dtol@ak.blm.gov
• Work as been proceeding at BLM but they down to one technician with funding estimated to last one more year, this work is winding down
