Remote sensing

Picture
Remote sensing means measuring an object at a distance without physical contact with it. In this section of podcast, fundamentals such as spectral signatures, real and false color image, ... are introduced.
These exercises are specifically targeted for K12 level student, just to introduce the Remote Sensing concepts, and some practical exercise with “Leoworks” a free software from ESA

 LEOWorks is a didactical tool with extensive help pages and an all-inclusive tutorial (see right of page). With the assistance of this documentation, students will be able to experiment with their own imagery and undertake their own processing. LEOWorks is compatible with data collected by several Earth Observation missions, and can read most standard image formats (e.g. jpg, tif, bmp, png).
LEOWorks 4 is the latest version of the software and it is platform independent (Windows, MacOS, Linux).

Presentation and suggestions for pedagogical exploitation of the CD-ROM : « Guyana seen through the clouds » (ESA)


Proposals for pedagogical exploitation
It can be interesting for students to discover the CD-ROM by themselves. But the teacher should first explain briefly how to use it, how to ‘travel’ through the CD-ROM.

Using a questionnaire might prove the best way for students to discover the CD-ROM (see below).  Students can go through the first questionnaire in groups of two or three. That work can first be marked and then corrected in class. The second questionnaire is meant to be answered individually, as a final test.
The presentation of the CD-ROM by the teacher and going through the CD-ROM by means of the first questionnaire in work groups should take two periods of 50 minutes.

Exercises about ozone
Objective
−Learn about the ozone layer and its variations
−Learn about measurements of the ozone layer
−Use of excel-software
−Graphic presentation of data
−Analysis of data
−Give an evaluation of different graphic presentations - be critical
−Develop own ideas for further analysis of the available data
−Use statistics
−Encourage to find recent data on the internet
−Encourage the students to ask questions and to try to find answers
​

Subjects that can be involved:
Physics: Satellite measurements, absorption of radiation
Geography: Ozone layer . Projections
Biology: Risk of high UV concentrations
Information technology:
–use of a calculation program (Microsoft Excel) to make calculations and draw graphs
–make an animation of a series of pictures (e.g. a GIF-animation by using freeware from the Internet)

Mathematics: Statistics

PHYSICS OF RADIATION IN REMOTE SENSING
There is no Remote sensing without physics.

Pupils should learn

  • which main physical laws are necessary for remote sensing
  • difficult physical laws could be demonstrated by excel

Practical work about Earthquake: Devastation and Recovery Bam, Iran
Level : These lessons are meant for forth-year students (14-15 year old students / secondary education - general)
Skill to be practiced: The students must be able to “look for the causes and the consequences of phenomena they have studied, as well as their interactions.”
Necessary background : It may be useful to explain what a satellite picture is. There is however no necessary background since the vocabulary that will be used can be explained during exercises proposed by the teacher. This sequence can either be an introduction to the issue of plate tectonics, or some exercises about that theory. It can also be integrated in lessons on natural catastrophes.
