With very high resolution (VHR) satellite it is now possible to carry out, using collected data from space, many applications that in the recent past were exclusive to airborne and on site surveys. Due to the high geometrical resolution, the multi-spectrality, the high radiometric sensitivity, the revisit capabilities, the area imaged by a single frame or strip and to the accurate geometrical processing that can be targeted, VHR imagery is a key source of information for a wide range of applications related to natural, semi-natural, urban up to desert environment. For example, a possible range of applications in this scenario can be: seasonal vegetation detection and monitoring, pasture monitoring and grazing paths, water points inventory, palm trees counting and monitoring, desertification expansion and sand mobilization mapping and monitoring. The paper also gives satellite data technical features and in general the capabilities of Very High Resolution in territorial problems solving. [ABSTRACT FROM AUTHOR] |
