  1. Watershed Dynamics Bill Carlsen Penn State University

  2. Authentic Inquiry Learning science “as science is practiced” • Real questions with unknown answers • Important problems (often local) • Socially constructed through collaboration, argumentation, and critical evaluation by peers

  3. Poll 1

  4. Object Recognition Using Airphotos • “Guide to Mostly On-Line and Mostly Free U.S. Geospatial and Attribute Data” (updated URL, p. 76) • http://libinfo.uark.edu/GIS/US.asp • ExpressView Browser Plug-in (MrSID) for .SID files • http://www.lizardtech.com/download/

  5. Reviewing Airphotos • Common formats: TIFF, SID, various GIS • Metadata files provide information on type of image, scale, location, year and season, coordinates, corrections, etc.

  6. Metadata Originator: USDA-FSA Aerial Photography Publication Date: 20041228 Title: NAIP 1-meter resolution mosaic of Centre County, Pennsylvania Abstract: This data set contains imagery from the National Agriculture Imagery … Format Information Content: MrSID Transfer Size: 333.747

  7. Key Indicators 1. Tone - gray scale 2. Texture - tonal repetitions 3. Pattern - spatial arrangement of objects 4. Size - dimensions of object 5. Shape - conformation, configuration 6. Shadow - a clue to size and shape 7. Location – what’s nearby?

  8. Object Recognition

  9. Test Your Remote Sensibility • What are the structures at D? • What direction is the water flowing? • What famous movie scene was filmed at F?
