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.
