What characterises Electro-magnetic radiation 1. Wavelength 2. amplitude - height of wave from centreline to peak 3. Polarization - orientation vector of photons 4. frequency - number of wave cycles Why can people get sunburnt whilst sitting in the shade 1. Reflected UV radiation 2. Scattered UV radiation - from atmosphere and clouds What is a high pass filter? - Image enhancement technique which enhaces the edges and finer details of an image - This is done by subtracting a lo...

What is remote sensing? - Knowledge and techniques used to determine the properties of targets without direct contact between the measuring device and these targets What is the only energy that can be transmitted through a vacuum or a medium? - Electromagnetic radiation What is resolution? - Characteristics of the sensor/imagery that determine the type of application What are the 4 types of resolution? - Spatial, spectral, temporal, radiometric What is spatial resolution? - Defined b...
