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

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

13
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
14
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
