Geophysical survey instruments are map-making technologies concerned with subsurface features in the ground and provide valuable information about groundwater, bedrock, sinkhole depth, mineral identification, archeological sites and more. Manufacturers of high tech imaging systems use electrical resistance meters that look like electrical meters to produce geophysical maps. Engineers and scientists use the readings from the instruments to produce 2D and 3D images with equipment from websites like AGIUSA.com. This industry offers technology on a worldwide basis to universities, corporations and governments to do geological surveys, natural resource searches and tasks like termite control studies.
Researchers first developed the resistance meter technology in the 1940s and 1950s for archeological digs. When it proved successful, other areas of geophysical research found applications of the meters. Companies and manufacturers provided the technology. With the addition of computers processing, industry advances happened because of the processing of large amounts of data. Many of today’s meters are lightweight, handheld wireless systems. To affect the quality of the mapping images, users manipulate the depth of the survey.
Product units offer portability, big memory storage and user defined measurement cycles. They work by thrusting metal probes into the ground to conduct tests. Users inject an electrical current through stainless steel probes in the ground to produce a reading. The software that works with the units offers many features like resistivity modeling and inversion, survey planning with graphical input modeling, noisy data suppression and many more. You can develop a well-organized, hassle-free data directory structure. The graphics are fast and scalable.
Organizations and companies who are looking for archeological, engineering and geological data can detect buried features when the physical properties contrast with the surroundings. Often, archeologists can identify metal artifacts in the imaging. The meter records the readings in memory and renders it as maps. The data can help guide excavation and give interested parties information about the object and everything around it without ever invading or destroying layers to find it. If you want to know if an earthen mound in a field is an Indian burial ground, this technology can make it happen without disturbing it.
Every task of geophysical mapping presents its own challenges and the technology of electrical resistance meters has evolved to meet the challenges. The information produced in image mapping is valuable to scientists and engineers and helps them make decisions about future excavations.
