APPLICATION OF PHOTO-INTERPRETATION AND REMOTE SENSING TO ENGINEERING GEOLOGY

APPLICATIONS DE LA PHOTO-INTERPRETATION ET DE LA TELEDETECTION A LA GEOLOGIE DE L'INGENIEUR

The use of photo-interpretation leads to a better means of defining the sectors to enclose in urban development by detecting terrain anomalies. It also affords a satisfactory approach to hydrogeological problems, facilitates investigations on materials, and points to the right direction of site studies and investigations to be conducted. Some examples of the application of the method are given. One example shows the use of photogeology applied to small-scale geotechnical mapping in equatorial zones. It enables a large area to be surveyed and complex geotechnical zones to be localized before an in-depth study is carried out. Example 2 relates to the problems which arose during the construction of the foundation of the arnon dam (cher, France): aerial photography enabled fissuration networks to be determined at the local level without having to define their regional importance. This method compared with satellite images showed the existence of a regional fault crossing the site of the dam. The fault was indeed found during construction operations. The third example describes how a 1/250000 map of the provence region was drawn from satellite images and aerial photographs. Problems arose in the processing of the data. /TRRL/
