Earth Observations For Geohazards Volume 1

Earth Observations (eo) Encompasses Different Types Of Sensors (e.g., Sar, Lidar, Optical And Multispectral) And Platforms (e.g., Satellites, Aircraft, And Unmanned Aerial Vehicles) And Enables Us To Monitor And Model Geohazards Over Regions At Different Scales In Which Ground Observations May Not Be Possible Due To Physical Andor Political Constraints. Eo Can Provide High Spatial, Temporal And Spectral Resolution, Stereo-mapping And All-weather-imaging Capabilities, But Not By A Single Satellite At A Time. Improved Satellite And Sensor Technologies, Increased Frequency Of Satellite Measurements, And Easier Access And Interpretation Of Eo Information Have All Contributed To The Increased Demand For Satellite Eo Data.
