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

  4. Orthos Example of an orthophoto tile: 4,000 feetby4,000 feet 1-foot pixel resolution.

  5. IGIC Orthophotography Workgroup 2005 Orthophoto Project Review Orthophotography has the geometric characteristics of a map and the image qualities of a photograph. These qualities allow for: • distance measurements • area calculations • determination of feature shape • direction calculations • determination of coordinates at a location

  6. What is Orthophotography • Definition: IGIC Orthophotography Workgroup What is an Orthophotograph? • A digital (electronic) aerial photograph that has been corrected to remove distortion from the camera & airplane movement and adjusted to fit the ground surface.

  7. IGIC Orthophotography Workgroup Cameras Distort Images All imagery hasspatial error dueto the distortingnature ofphotography. & Don’t forgetTerrain Distortion

  9. 2005 Orthophotography Product Sets Product Set #3: High-ResolutionNatural Color Orthophotography Product Set #1: Quarter-Quad Color Orthophotography (1-meter re-sampled) Product Set #2: County Mosaics Color Orthophotography (1-meter re-sampled) Product Set #4: Color-InfraredOrthophotography (1-meter re-sampled)

  10. Coordinate Systems IGIC Orthophotography Workgroup • Indiana East &Indiana WestState Plane Coordinate System (feet) • UTM Coordinate System (meters) • NAD83, NAVD88

  11. Elevation Products IGIC Orthophotography Workgroup Digital Surface Model(DSM) Digital ElevationModel(DEM)

  12. IGIC Orthophotography Workgroup Products (cont.) • Base product: 1-foot pixel tiles • Buy-up: 6-inch pixel tiles 13 Counties • and… Control & QC & validation & PM & Portal & EOC & Libraries, etc.

  13. 2005 Funding IGIC Orthophotography Workgroup • One-time DHS grant • & other Federal grants • & County buy-ups • & State Agency Funding • $7.5 million

  14. IGIC Orthophotography Workgroup 2005 Ortho Project Benefits • 1.2 : 1 cost benefit ratio, without operations • $1.7 Billion worth of project and operationssupport

  15. ONGOING Orthophotography PROGRAM IGIC Orthophotography Workgroup • 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

  16. COSTS of an Ortho PROGRAM IGIC Orthophotography Workgroup 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

  17. FUNDING for an Ortho PROGRAM IGIC Orthophotography Workgroup Indianahastentativefunds ~ $1 million from: IN-DHS, IDEM, INDOT, USGS, grants and Counties?

  18. 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?

  19. 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?

  20. 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

  21. 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 )

  22. Proposal Review & Contracting IGIC Orthophotography Workgroup • RFP release – March-April 2010 • Responses due – May • Vendor selection – July • Contract negotiations – August • State Contract (MBE/WBE, Indiana vendors, etc.) • Imagery Capture – Feb thru mid-April, 2011 • Imagery Delivery – June-July, 2011 • Renegotiate for 2012 / 2013 / etc.

  23. IGIC Orthophotography Workgroup Comments & Suggestions & Questions Jim StoutIMAGIS Program Managerjrstout@iupui.edu317-327-2321
