one of the assignment is about bush fire in Australia back in 2009
1. remote sensing(RS): a phenomenon, object, or material by a recording device not in physical, intimate contact with the feature under surveillance
2. question in quiz: remote sensing & earth observation
Both: satellite observation for weather forecast weather satellite weather observations
earthquake and volcano monitoring with acrial and satellite sensors terrestrial and satellite
land use monitoring with aerial and spaceborne imagery using airborne and space images to monitor land use
RS only: X-ray
mapping the terrain of Mars with satellites with the satellite rendering topographic map of Mars
EO only: measuring sea level with tide gauges验潮仪
monitoring beach erosion with GPS(because you actually touch the beach)
3. quiz: optical remote sensing optical remote sensing
most optical remote sensing can be classified as passive remote sensing被动遥感, not all optical remote sensing are passive remote sensing
eg LiDAR is an active optical remote sensing lidar
Most microwave remote sinsing is active, but not all
4. challenge: the lake like a mirror, so the radar to reach the lake is reflected away, so the photos look very dark
5. optical imagery is affected by clouds, rader imagery will not
6. resolutions
spatial resolution the spatial resolution: pixel size pixel size
temporal resolution temporal resolution: sampling interval sampling interval, repeat cycle, revisit time
spectral resolution spectral resolution: bandwidth Bandwidth
radiometric resolution radiometric resolution: levels of energy magnitude energy level
7. wavelength
Exam type: choice, short answer, computing
