  1. An Orthoimagery Program for ME GeoLibrary Geospatial Work Group

  2. 2009 Geolibrary Strategic Plan • Stakeholders input gathered through forums, on-line surveys and personal interviews • Government • Academia • Business • Not-for-profit organizations • The need to provide current and accurate geospatial data was at the top of the list of stakeholder needs • Current high resolution orthoimagery was on everyone’s list • The Geolibrary established a subcommittee to make recommendations for new statewide orthoimagery

  3. Orthoimagery Subcommittee • Dan Walters - Chair, US Geological Survey • Sarah Tucker - Town of Bethel • Tom Marcotte - Maine DOT, Office of Information Technology • Brett Horr - Town of York • Greg Miller - Maine Forest Service • John Root - City of Rockland • Larry Harwood - Maine Office of GIS, Office of Information Technology • Brian Norris - James W. Sewall Company • Ken Murchison - Northern Maine Development Corporation • Sean Gambrel - City of Bangor

  4. Phase 1 – getting the committee up-to-speed • Review the users needs • Understand the state-of-the-art for orthoimagery production • Review Existing Standards and Specifications • National Map Accuracy Standards (NMAS) • Content Standards for Digital Orthoimagery • National Standard for Spatial Data Accuracy (NSSDA) • Model USGS Orthoimagery specification published for the ARRA Orthoimagery program

  5. Phase 2 - What’s Realistic • Reasonable annual budget • Not practical to acquire entire state in one year • Must break state into groups • Not all areas need new imagery at the same rate • Need to consider varying refresh cycles • All major stakeholders must help fund the work • There needs to be a schedule so organizations can budget

  6. Phase 3 - Program Recommendations • Letter of support for federally sponsored “Imagery for the Nation” • 11 groups flown on a rotating cycle of 3 years (groups 1-3) or 5 years (groups 4-8 & groups N1-N3) • Base resolutions of 2 foot (groups 1-8) and 3.3 foot (groups N1 – N3) • Published schedule of when each group would be flown • Facilitate buy-ups with funds from organizations interested in high quality products • The imagery would be natural color and flown leaf-off in the spring without snow • Airborne GPS and IMU will be used for control • 10 meter USGS DEMs will be used at a minimum for orthorectification • Use USGS base orthoimagery specifications will be used as a guide for all contracts

  7. Specifications: 11 groups flown on rotating basis Groups 1-3: every 3 years Groups 4 – 8: every 5 years Groups N1 – N3: every 5 years Groups 1 – 8: 2 foot resolution Groups N1 – N3: 3.3 foot resolution Example: Groups 1, 4 and N1would be flown in year 1. Group 1 would be flown again in year 4 while groups 4 and N1 would be flown again in year 6. About $500,000/year Local buy-ups to upgrade products

  8. Program Status • Program to start 2012 • 2012 > Groups 3, 4 & N1 • 2013 > Groups 2, 5 & N2 • 2014 > Groups 1, 6 & N3 • 2015 > Groups 3 & 7 • 2016 > Groups 2 & 8 • Working with federal, state and county agencies for base program funding • Towns can buy up • Need commitments before 10/1/11, but sooner is better

  9. Program Status (continued) • Exploring 3-way split between federal, state and county • Will be year-to-year until program gains momentum, value is realized and appears as regular item in stakeholder budgets • Positive meeting with county administrators • County administrators established subcommittee to initiate discussions with county commissioners • GeoLibrary applied for return on investment grant from FGDC with support letters from 4 state agency commissioners • GeoLibrary plans to apply for USGS Partnership funds

  10. Projected cost for 5 year statewide contract

  11. How do towns benefit? • Orthoimagery subsidized by base program • Economies of scale of statewide program provide additional savings • Administrative costs of program are shared across all communities • Financial participation from other stakeholders for buy-ups

  12. What can you do to support the program? • Letter to county commissioners encouraging county financial participation • Letter of financial commitment to buy-up as soon as possible to build momentum for program • Explain importance of state government participation as the opportunity arises
