f GPR as an economical advantage of geological, archaeological and engineering projects

Geophysical methods are weIl known as supplement for classic investigations like drillings or digging. In most cases Geophysics is used to delineate the areas where excavations or probing has to be done. The increasing cost of construction work and the decreasing money and time for different jobs demand economical and fast methods to view the subsurface structures possibly without digging. The increase of computing power and experience in GPR-applications lead to more investigations with geophysicaI methods replacing conventional testing. Although the combination of different methods is best in getting most significant results often Iittle money will be paid for investigations. So a tight measuring program mostly has to be calculated. GPR is a multipurpose system that yields fast non-destructive information of the ground. Without extensive data processing first results often can be reached on site. So it should be qualified for different projects standing under strange economical conditions.
