IGIC Orthophotography Workgroup
This group was responsible for the 2005 This group was responsible for the 2005 Statewide Orthophotography ProjectStatewide Orthophotography Project..
Recognizing the critical need for up-to-date Recognizing the critical need for up-to-date photos, the Workgroup is developing a photos, the Workgroup is developing a PROGRAMPROGRAM to update Indiana's orthos on a to update Indiana's orthos on a regular rotating basis.regular rotating basis.
The work includes developing: The work includes developing: planning planning documentsdocuments with technical specifications, a with technical specifications, a Request for ProposalRequest for Proposal, and documents to , and documents to educate the publiceducate the public and elected officials on and elected officials on the benefits of the program.the benefits of the program.

2005 Ortho Project Benefits
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
ONGOING Orthophotography PROGRAM
• Regular Refresh Rates (on-going value) Currency of Data
2005 is a long time ago Planning (for communities & vendor) Scheduling (budgets & projects)
• Vendor Relations May be value in multi-year contracting Vendor incentives for quality

COSTS of an Ortho PROGRAM
Indiana has 40,000 sq.mi. (103,600 sq.km.)
• Satellite (.5m=20in) ~ $1.3 million• One-foot orthos ~ $5.7 million• Six-inch orthos ~ $8.5
million

FUNDING for an Ortho PROGRAM
Indiana has tentative funds ~ $1 million
from:
IN-DHS, IDEM, INDOT, USGS, grantsand
Counties?
IGIC Orthophotography Workgroup
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
So what PROGRAM can we afford?
IGIC Orthophotography Workgroup
• Six-inch for 1/8 of the state per year, or
• One-foot for 1/6 of the state per year, or
• Satellite of 8/10 of the state per year, or
A mixture?

How do we incent Counties?
IGIC Orthophotography Workgroup
• Make the base product low-reswith buy-up options How does this work w/ satellite?
• Provide the funds of the base product to counties who fly their own photos Most counties don’t fly much Many counties don’t have funding Cooperate with the State?
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
So, here is our thinking:
IGIC Orthophotography Workgroup
• Capture 1/3 of state/year• Fewer product sets
Just photos (no mosaics, one projection)
No infrared, No DEM
• Base product is low-res Satellite or 2-foot photos Buy-ups: 1-ft & 6-in,
or help counties fly

Request for Proposal
IGIC Orthophotography Workgroup
• Quotes for large area (10,000+ sq.mi.), for: 2-foot photos 1-foot photos Other options (DEM, CIR, mosaics, web posting)
• Quotes for multi-county (4,000+ sq.mi.), for: 6-inch photos
• Technical Ability / Accuracy• Capacity (coverage brings more players)• Guarantees ( flights / delivery / rejects )
