-Visible wavelength is used to make digital elivation models, and to determine population density.(IKONOS),(MODIS)

    -Near infrared (MODIS) is used to map flooding.

    -Shortwave infrared can image water vapor.

    -Microwave can messure rainfall (Meteosat), flood map (AMSR-E) and 3d storm structure

   -Flood maping can use (MODIS) 

 

What are some examples of platforms used?

-IKONOS:IKONOS is a commercial earth observation satellite,

-MODIS:The Moderate-resolution Imaging Spectroradiometer

-Meteosat:The Meteosat series of satellites are geostationary meteorological satellites operated by EUMETSAT under the Meteosat Transition Programme
