Presentation Transcript

  1. Satellite and Aerial Image Analysis

  2. Remote Sensing • Earth Observation • Photogrammetry Application Areas: anything that happens on the planet From the Cold War to Spaceship Earth

  3. Imaging Tech • Satellite / Aerial Photography • Geosynchronous / • Sunsynchronous (Near Polar Orbit) • Passive / Active; Panchromatic / Multispectral • Data processing, distribution, corrections • Interpretation

  4. Pixel Classification • Vegetation, Soil, Water, Ice, Atmosphere • Radiation proifles

  5. MODIS Rapid Response Fire Maps • Vital product aids firefighting responses • Fully automated • Straight forward algorithm, placing conditions on multiple spectrums

  6. Remote Sensing at Sussex • Dominic Kniveton, WetNet project • Rainfall estimation from microwave radiation

  7. Ice Edge and Icebergs • Climate change and wildlife • Economic (shipping) • Traditional livelihoods • Techniques • Spectral profiles, and microwave backscatter for classification • Edge and motion detection

  8. Neural Networks • often used in geography • Snow density estimation • ANNs trained on site specific data performed better than known algorithms

  9. Automated Road ExtractionActive research area, many places currently badly mapped Technique for updating accuracy of existing maps is completely automated, successful

  10. 3D City Models • Similar technique of extracting above ground objects • Aerial photos are then texture mapped to models.
