Progress in Tele-detection: Instruments and their Applying

Abstract

The author points up the great strides made of late in the world of Applied Geographical Technology
(TIG) thanks to the developing of novel information sources and modes of analysis such as teledetection.
This latter is seen as offering a unique way of analysing events and processes that occur
within Territory. Spatial tele-detection is seen as being endowed with a whole series of advantages
when compared with alternative methods of observing the Earth and to offer amongst much else
the possibility of observing its surface as a whole, an ability to reveal information in regions hidden
from the spectrum this and its capacity to give information at varying scales and at distinct temporal
frequencies.. The article goes over the evolution and future tendencies of the major missions of
tele-detection and analyses the nature of new instruments of information gathering and their
applications, highlighting here the progress made in hyper-spectral tele-detection and LiDAR. A
summary of the most recent applications that best point up tele-dection’s operative effectiveness
as a tool for territorial managing at its varying levels is also included.
