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

Pixel Classification Vegetation, Soil, Water, Ice, Atmosphere Radiation proifles

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

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

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

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

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

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