and contemporary digital airborne photography, we find
that the traditional camera (either film or digital) is still
the most commonly used sensor (13,5%). LiDAR (Light
Detection And Ranging), RADAR and TIR (Thermal
InfraRed) sensors are also well cited with respectively
13.5% 11% and 9% of manuscripts. Spaceborne sen-
sors such as ASTER (Advanced Spaceborne Thermal
Emission and Reflection Radiometer), MODIS (Moder-
ate Resolution Imaging Spectroradiometer) and MERIS
(Medium-spectral Resolution Imaging Spectrometer) are
also cited. Airborne hyperspectral imagers such as CASI
(Compact Airborne Spectrographic Imager) are less fre-
quently cited (3%). 'Terrestrial remote sensing' is also
cited with devices such as TLS (Terrestrial Laser Scanning,
0.5%), LSPIV (Large Scale Particle Image Velocimetry,
3,5%) and ground-based video (6%).
We also explored the temporal trend of the plat-
forms/sensors used for the most frequent (Figure 1.5).
Two relative references were used, the 15 000 manuscripts
focused on river management and stored in the WOS,
and the 200 papers studied without distinguishing any
method. These two cumulated curves show the WOS
database prior to 1990 is not very rich and the steep
trend we observed in recent years is also partly due
to the database structure itself. When looking at the
relative cumulated curves per year for the different
platforms/sensors, two groups can be observed: Pioneer
platforms/sensors such as photograph and Infra-Red for
which the median year is 2000 and their use seems
to decrease a bit after, and new sensors such as TIR
(median year 2005), SAR/Radar (median year 2006) but
also LiDAR (median year 2008). Airborne/Aerial data,
Landsat and video seemto follow the general trend in term
of publications. However, Landsat seems more popular
in the 1998-2004 period and its relative use is decreasing.
1.3.3 TopicalAreas
An examination of the abstracts revealed that FRS is
contributing to a large set of topics that we can group
into three broad areas (Figure 1.6). First, the drive for
a better science base in management decisions has seen
remote sensing applied to ecological and habitat studies
aiming to identify land-use types, specific habitat types
and biotopes (37% of papers). Second, investigations in
water sciences which are related to the fields of water
