Satellite and Aerial Image Analysis
Remote Sensing
Earth Observation
Photogrammetry
From the Cold War to Spaceship Earth
Application Areas:anything that happens on the planet
Imaging TechSatellite / Aerial Photography
Geosynchronous /
Sunsynchronous (Near Polar Orbit)
Passive / Active; Panchromatic / Multispectral
Data processing, distribution, corrections
Interpretation
Pixel ClassificationVegetation, Soil, Water,
Ice, Atmosphere
Radiation proifles
MODIS Rapid Response Fire MapsVital product aids
firefighting responses
Fully automated
Straight forward algorithm, placing conditions on multiple spectrums
Remote Sensing at SussexDominic Kniveton, WetNet
project
Rainfall estimation from microwave radiation
Ice Edge and IcebergsClimate change and
wildlife
Economic (shipping)
Traditional livelihoods
TechniquesSpectral profiles, and
microwave backscatter for classification
Edge and motion detection
Neural Networks often used in geography
Snow density estimationANNs trained on site
specific data performed better than known algorithms
Automated Road ExtractionActive research area, many places
currently badly mappedTechnique for updating accuracy of existing
maps is completely automated, successful
3D City ModelsSimilar technique of
extracting above ground objects
Aerial photos are then texture mapped to models.
