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
