Remote sensing at the University of Hong Kong

 Meteor Crater in Arizona is one of the youngest and best preserved impact craters on Earth. Here you see two images obtained by the AVIRIS instrument. The left one shows a false colour image that is similar to what your eye would see. The right one is a principal component image processed to emphasize mineralogical differences.

One of the most important skills required for working in modern geological, environmental or climate sciences is the ability to understand remote sensing data.

What is remote sensing?  Technically, it means studying something without touching it - which can apply to many types of analyses. But in reality, when someone says remote sensing, what they usually mean is the study of the surface of the Earth or some other planet using an instrument aboard and orbital spacecraft or an airplane. These instruments measure visible light -  like a digital photo, infrared radiation - to measure composition or temperature, radar - to study surface shape and topography, and many, many other things.

Satellite images you see on Google Earth of our planet's surface....weather maps showing clouds and precipitation...images of cities used for urban planning around the globe...Maps of minerals and rocks on the Moon or Mars...images of geysers on Europa...,all of these are examples of remote sensing. And, there are countless other applications.

If you want to learn how satellite remote sensing works, come take my class at HKU: Environmental Remote Sensing (EASC 3405). In my class, you will learn how to:

  • Obtain and view satellite images
  • Interpret data collected from remote sensing instruments
  • Work with satellite data to extract critical information for urban planning, climate studies, geological exploration or analysis of other planets
  • Recognise and correct problems with remote sensing data
  • Apply remote sensing data to solve a scientific problem
  • Write a report or present results describing your findings
  • Work with cutting edge software that will help you find a job!
