1 Introduction to Remote Sensing Spatial, spectral, temporal resolutions Image display alternatives Vegetation Indices Image classifications Image change detections Accuracy assessment Satellites & Air-Photos
2 Selected RS Systems Landsat TM & Enhanced TM (Thematic Mapper) Ikonos & Quickbird MODIS (Moderate Resolution Imaging Spectrometer) Radarsat & ERS (European RS Satellite) SeaWiFS (Sea-Viewing Wide Field-of-View Sensor) GOES (Geostationary Operational Environ. Satellite) AVHRR (Advanced Very High Resolution Radiometer) SPOT (High Resolution Visible) Others
3 Digital Satellite Data Remote sensing: the acquisition of data about an object or area by a sensor that is physically far from the object or area. Digital satellite data is one type of remotely-sensed data aerial photography is another type of remotely-sensed geographic information Important advantage of remote sensing data: synoptic perspective: comprehensive view of large areas of the Earth s surface, vantage point of observation, digital format, multispectral, multi-temporal, multi-spatial.
4 Satellite Data - Benefits & Problems Benefits: it is already digital (unlike standard aerial photos) -- readily lends itself to manipulation and analysis to extract useful information synoptic perspective repeat coverage of areas minimal scale and geometric distortion problems relative to aerial photos Problems: generally low spatial resolution compared to aerial photos large data storage volumes distortions in data values due variations in atmospheric conditions, clouds, terrain, solar angle, etc require preprocessing to correct!
5 Electromagnetic Spectrum (EMS) Visible Portion At a given Temperature, T Cosmic Gamma X-rays UV Infrared Microwave Radio/TV Rays Rays Near/Medium/Thermal Wavelength in Micrometers (= 10 3 nanometers) Increasing Wavelength Increasing Frequency and Energy

7 Passive (Optical) Sensor Technology Incoming EMR Reflected EMR Emitted EMR
8 Electromagnetic Radiation Spectrum Remote sensing satellites record data on electromagnetic radiation (EMR) satellites have detectors that record specific wavelengths in the EM spectrum EM radiation interacts with physical matter some wavelengths are absorbed & others reflected determine/estimate matter type by analyzing spectral signatures in satellite data
9 The Four RS Resolutions Satellite data characterized by four resolutions: spatial resolution: area on ground represented by each pixel (cell) in the satellite data. temporal resolution: how frequently a satellite platform obtains imagery of a particular area, orbital characteristics. spectral resolution: specific EM spectrum wavelength intervals captured/recorded by a particular satellite sensor. radiometric resolution: number of possible data values recorded/reportable by each satellite sensor, precision with which the EM spectral values are reported.
