Applications of Close-range Imagery in River Research - Fluvial Remote Sensing for Science and Management - page 352

(that can be acquired with different distance to the
object, orientation, even date) and takes advantage of
free and open-source software. This procedure is capable
of producing a low-cost 3D mapping that can be used for
a wide range of applications in geophysics.
Methodological and technological progresses are evi-
dently expected since ground imagery represents one of
the main emerging fields in remote sensing. In terms
of river management, these approaches are particularly
relevant as they improve our understanding of the mor-
phological processes, helping us to manage the river
environment using an understanding of real-time causes
not only the observed (post flood) consequences. More-
over, the development of web-platforms could provide
easy access to online, remote information, with relevant
advantages in public communication (a picture may be
worth 1000 words from a scientist) and security (e.g.,
development of flood warning systems).
