At 586,400 square miles, Alaska At 586,400 square miles, Alaska is as wide as the lower 48 statesis as wide as the lower 48 statesand larger than Texas, California and larger than Texas, California and Montana combinedand Montana combined

Size and Distance Comparison

Some Guiding Principles

1)Establish a mapping program within AK that is commensurate with the mapping program for the lower 48 to meet high priority needs for safety, planning, research and resources management applications across multiple communities of use2)Seek partnerships with the AK stakeholders for leadership in defining, communicating and funding mapping activities with emphasis on elevation and imagery under the SDMI. Coordinate efforts with recently completed business plan (CAP grant). 3)There is a scarcity of suitable data. This will require even greater emphasis and creativity working with Alaska state agencies and other stakeholders for acquisition.4)Alaska maps will be mass-produced products. Upgrading source databases, via bulk data collections and partnerships, and remaking US Topos on a cycle (as opposed to extensive research and attention to each individual map) are the primary mechanisms for improving the overall accuracy and completeness of the series.

Proposed Characteristics for Statewide US Topo Products in AK

Use scale of either 1:25K or 1:50K (to achieve statewide coverage this cycle)

Use AK DNR SPOT orthoimagery (2.5m resolution) --currently underway with 3+ year production remaining

Use IFSAR (or LIDAR where available) for contours -- currently ~20% of AK in work or complete; 7+ years @ current rate

Use TomTom for trans & structures (seek alternatives or augment)

Use NHD & GNIS: assess likely level of effort to align w/ new image & contours.

Use State Department International Boundaries Use BLM for Federal and Borough Boundaries

Evaluate statewide options for other feature layers, most notably boundaries and PLSS

Three normal airborne IFSAR products

Could register satellite imagery to ORI to improve positional accuracy with minimal GCPs

Deliverables include: pseudo natural-color, CIR, and panchromatic

Key Technical and Programmatic concerns

General lack of suitable statewide data & difficulty of collection

Risks inherent in dependency on external data programs (e.g. delays, accuracy, pace, and the difference between the ortho and IFSAR efforts)

Challenge of schedule, objectives, and source staging for pilots

Challenge of placing and training new hires

Data integration efforts are unknown

Need for development for irregular map extents

18 cells (IFSAR license “uplift” area)

19 cells. Neither the city of Fairbanks nor any part of Denali National Park have coverage.

Standard Cells Covered completely with both IFSAR and SPOT in 2012

Cells are those used for the 1:63,360 legacy series. 15’ in latitude, vary in longitude.

Coordination Efforts

Coordination with USGS Alaska Science Center

Coordinate with AK DNR for SPOT Imagery and Ortho Production

Contribute to SDMI IFSAR program.

Coordinate efforts with recently completed a business plan (CAP grant).

Local contact with other federal agencies through Alaska Science Center and Liaison network and the Alaska Geographic Data Committee

Participating in Upcoming Alaska Surveying and Mapping Conference Preparation of draft sample products and developing feedback mechanisms, Meet with partners and Communities of Use

Increase staffing – Assign Project Coordinator; Refocus Idaho Liaison to Alaska; Hiring AK

Liaison Hiring Technical Operations Center personnel
