The advances in technology are evolving at a really fast pace in regards of the
techniques we used to use in the past decades. Such advances have been
even more radical in the fields of geomatics that have reached such
perfectioning limits only imaginable if coming from great revolutions, both in the
scientific and technological fields.
The new technologies, that were only used in a concrete field of work in the
past, are now being used in other fields of work that were once unthinkable.
Science based in ofimatica has made this progress easier by making these
processes, once slow and expensive, much easier at the same time it has
improved their results’ precision. Thus obtaining an optimization and
optimization that exponentially improved the topographic procedures and, along
with it, of many other disciplines of the technologic and scientific side.
All these improvements are being applied in the fields of topography, engineery,
architecture and construction between many others. Technologies such as the
3D viewing of an object, thermographic cameras, along with all kinds of
measurers, calculus programs, etc. that have spurred the worker's productivity
along with the companies' itself, with the valuable add up of the improvement of
the quality of human work.
The Topography in concrete, this improvements, had made us go from chains,
compasses, displacements and plumbs, to handling GPS's, 3D digital scanners
and computer measurements along with the evolution of electronic devices.
Thanks to the latter, such simple task as to get angles, is now way faster, more
effective, and more precise than it was back in time. With the actual total
stations a huge improvement has been made in the angular reading and
distance reading, not forgetting the motorized point stakeout stations along with
the robotized, that by using a search and following system for a prism allows the
data collection without an operator handling the station. Without further ado to
get even deeper inside the history of the evolution of the topographic
measurement apparels, we cannot leave the development of the Global
Positioning Systems without a mention. They have given us access to the realtime
data collection with the Geographical Information Systems along with
images captured from satellites giving way to new techniques in the remote
sensing field. With everything said above, there is no doubt that we have greatly
widened the old traditional limits that the measurement instruments and
cartography itself once had.
But, despite all these improvements and new technologies, along with the great
changes in the applied methods used. The traditional concept of Topography still
remains the same it was in Egiotian times. It is also curious how iside the same field it
is still looked after a more "artisan" way of work, especially in the tasks of heritage
architectural surveys, that would be needed for any project of subsidence, reform or cataloging, which is precisely the objective of this work. The objective of wich is the
reconstruction of 3D model of the Roman ruins of La Llosa of Cambrils.
Paper, pencil, and measuring tape are still considered useful field tools along with the
photographic camera (to check the sketch). Photography and measuring tools
converge in the field of photogrammetry with which we get the real magnitude
represented in the photographic images allowing us to measure real distances over the
graphical documentation obtained in the processing of the same. Photogrammetry has
brought many advantages, especially by reducing the field work and by obtaining
precise plans. |
