3. Agenda • What is Orthophotography? • The Politics of a Statewide Project. • The Technology. • Deliverables. • Where we are Today.

5. Project Administration • Politics - 2 administrations • Funding • Contract negotiations • IGIC Orthophoto workgroup • State: • Roger Koelpin (State GIS Coordinator. ITOC) • James Robb (Program Manager, IDEM) • Bob Wilkinson (Staff/Surveyor, IDNR) • EJ McNaughton (Agency GIS Director, IDEM) • Bob Burns (Staff, INDOT) • Caitlin Intermil (HLS Grants Coordinator, SEMA) • County and Municipal: • Bill Holder (GIS Director, Kosciusko Co) • Jim Stout (Program Manager, IMAGIS) • John Thomas (GIS Director, City of Lafayette) • Larry Stout (GIS Director, Hamilton Co) • Matt McCormick (Photogrammetrist, IMAGIS) • Randy Smith (GIS Director, Monroe Co) • Betty Kiechle (Staff, Office of the Lake Co Surveyor) • David Smoll (Hancock County Surveyor) • Matt Arvay (Chief Information Officer, Vanderburgh Co) • Todd Kesselring (GIS Director, Elkhart County) • University: • Anna Radue (Faculty, Data Management and Support Services, UITS, Indiana University) • Larry Beihl (Professor, Purdue University) • Jim Bethel (Professor, Purdue University)

6. Orthophotography Project Partners • Indiana Counter Terrorism and Security Council • All 92 Indiana Counties • State Emergency Management Agency (DHS) • US Geological Survey • Indiana Department of Environmental Management • Indiana Department of Natural Resources • Indiana Criminal Justice Agency • IMAGIS • Indiana Geographic Information Council

7. Why Orthophotography? • 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 given location.

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

9. Cameras Distort Images • All imagery hasspatial error dueto the distortingnature ofphotography.

10. Acquisition • Vendor Selection.> capacity> technology> value added deliverables • Photo Missions. • Pilot. • Processing & Delivery.

11. Quality AssuranceCritical Part of Project • Vendor Selection • Open and Evaluate Every File • Accuracy Review • Aesthetic Review • Distribution of Final Products

13. ISTAR / Earthdata www.earthdata.com

14. GeographicCoverage • Entire state of Indiana, plus 1000’ buffer around boundary of state. • Includes to edge of opposite river bank on Ohio and Wabash Rivers. • 13 “buy-up” Counties.

15. 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)

16. Orthophotos will be “Tiled” ~70,000 Tiles!!!

17. Delivery Coordinate Systems • Indiana East &Indiana West State Plane Coordinate System (feet) • UTM Coordinate System (meters) • NAD83, NAVD88

18. Deliverables • Deliverables • Delivery 1 – TIFFs and 1:20 MrSID Tiles • Next Deliveries • 1:50 MrSID Township Mosaics (State Plane) • 1:50 MrSID Township Mosaics (Lat./Long.) • 1-meter resampled county mosaics (UTM) statewide set • Value add – AccuGlobe w/Township mosaics and addt’l vector data; ArcReader Emergency Response Map • DEM/DSM • 1-meter Color IR (UTM) • Supplemental Delivery – relight areas only

19. Delivery File Formats • Conventional files formats can be used with almost any system • TIFF with World Files • Compressed MrSID Files • County Mosaics (MrSID) • .IMG format for elevation models

20. Accuracy Specification has 3 “Flavors”

22. Orthos Example of one orthophoto tile: 4,000 feet by4,000 feet 1-foot pixel resolution.

23. 1-foot pixels

25. Elevation Products Digital Surface Model (DSM) Digital Elevation Model (DEM)

26. DEM • A DEM is a series of points which have X,Y,Z coordinates. • DEM’s are used to correct relief displacement (ortho-rectify) in the imagery. • Without further processing, the DEM can hold 10’ contours • With further processing, the DEM can be used for 2-foot contours.

27. Uses of Color-IR • Mapping and feature extraction of water bodies, wetlands, impervious surfaces, and land cover. • Useful for applications such as drainage management, land cover mapping, and water quality.

28. Digital Color-IR “false color” 1-meter resampled
