The use of satellite imagery, image processing, and computerized cartographic tools have become essential. These technologies are applied to many sectors, such as power line corridor selection, environment, geology, forestry, hydrology, agriculture, and hydrocarbon exploration. Ground Penetrating Radar Surveys Ground penetrating radar is a geophysical method that generates a continuous profile of the subsurface. The high precision of this technique can provide much information in a rapid and cost effective manner. These surveys can be done by vehicle, while airborne surveys can be done in difficult locations.
Electrical surveys have the advantage in being fast.
Geological information obtained by these surveys allow for a reduced number of boreholes with better locations. These surveys can be used to derive different materials parameters by measuring and analyzing variations of the electric potential from the surface. These methods can measure the variation of the natural or artificial magnetic field in order to detect geological anomalies. This type of survey is used to locate faults, mineralized zones, and underground structures associated with ore deposits, as well as oil fields. Geophysics GPR International Inc. has the most modern and precise magnetometers available.
