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? What is Orthophotography  Definition:  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 has spatial error due to the distorting nature of photography.

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

11. Quality Assurance Critical 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. Geographic Coverage  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 #1: Quarter-Quad Color Orthophotography (1-meter re-sampled) Product Set #2: County Mosaics Color Orthophotography (1-meter re-sampled) Product Set #3: High-Resolution Natural Color Orthophotography Product Set #4: Color-Infrared Orthophotography (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” Pixel Resolution (Ground Sample Distance) NSSDA Horizontal RMSE Accuracy (95% of points) 1-meter pixel (resampled) 1-foot pixel 5 feet or better 6-inch pixel 2.5 feet or better

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

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
