An Orthoimagery Program for ME
GeoLibrary Geospatial Work Group
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
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
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
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
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 N1wouldbe flown in year 1. Group 1 wouldbe flown again in year 4 while groups4 and N1 would be flown again inyear 6.
About $500,000/year
Local buy-ups to upgrade products
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
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

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
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
