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气象卫星天气观测
earthquake and volcano monitoring with acrial and satellite sensors陆地和卫星
land use monitoring with aerial and spaceborne imagery利用航空和航天图像进行土地利用监测
RS only: X-ray
mapping the terrain of Mars with satellites用卫星绘制火星地形图
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光学遥感
most optical remote sensing can be classified as passive remote sensing被动遥感, not all optical remote sensing are passive remote sensing
e.g. LiDAR is an active optical remote sensing激光雷达
大多数microwave remote sinsing是主动的，但不全是
4. challenge：湖面像镜子，所以雷达到达湖面会被反射走，所以照片看很黑
5. optical imagery会受云的影响，rader imagery不会
6. resolutions
spatial resolution空间分辨率：pixel size像素尺寸
temporal resolution时间分辨率：sampling interval采样间隔，repeat cycle, revisit time
spectral resolution光谱分辨率：bandwidth带宽
radiometric resolution辐射分辨率：levels of energy magnitude能量级
7. wavelength
考试类型：选择，简答，计算
