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

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
