This presentation refers in the first place to the new global perspective of environmental
monitoring. As important and very much interdependent for the proper management of
planet Earth is the environmental monitoring at micro level. At this level education faces
similar challenges although the tool box becomes more diverse: the advent of space obser
vation with a higher spatial (1-5 meters) and spectral resolution is significant to comple
ment airborne remote sensing. Social, economic, cultural and ethical factors influencing
the environment present challenges to education, which have not been elaborated further
in this paper.
However, students should become aware of the need for technology assessment to avoid or
reduce the negative social effects of new technology. In GIS and remote sensing this may
include aspects of privacy, access to digital data bases, the concentration of information,
resource exploitation in developing countries by western nations.
So what are the challenges for education given these conditions? They are to develop:
(1) knowledge and use of appropriate tools for monitoring (RS and GIS);
(2) interdisciplinary perspectives and communication;
(3) questioning of established paradigms and techniques;
(4) attitudes and skills to influence decision makers.
1. Instrumental Training in Remote Sensing and G.I.S.
Measurements of phenomena with short temporal scales covering large areas can not be
done simply by conventional point samples, but require repetitive area measurements
which can only be achieved by remote sensing.
Processes with both large spatial coverage and long temporal scales, such as ozone-hole, El
Niño current, desertification, deforestation, require archives to detect environmental
change rates retrospectively. For both these processes satellite imagery seems the only
feasible tool. A classical example of the use of remote sensing is the retrospective confir
mation of the widening stratospheric Antarctic ozone-hole by analyzing imagery produced
by the TOMS scanner on the NOAA Nimbus-7 satellite (Stolarski 1988).
Remote sensing not only extends the spatiotemporal possibilities for observation, it also
increases the number of sensors. Visible, Infrared, RADAR and thermal sensors are be
coming to produce satellite imagery.
But this multitude of new sensors for data collection have generated a data overload in the
bio- and geosciences. In remote sensing much filtering, decoding, preprocessing and com
pression of raw data into information are necessary.
GIS is indispensable in the handling of short temporal and/or large spatial scale environ
mental data and for the analysis and prediction of temporal and spatial trends. Also
linking with socio-economic models becomes feasible. GIS has the most appealing faculty
to deal with scenario’s in space and time based on different assumptions about environ
mental management strategies.
