TERRA EXPLORATION GROUP SPECIALIZES IN PROVIDING SIMPLE SOLUTIONS TO EXTRAORDINARY GEOPHYSICAL SURVEY NEEDS SUCH AS LOCATING CAVES AND TUNNELS, UNDERGROUND WATER, MINERAL DEPOSITS, AND EVEN BURIED CACHES IN DIFFICULT TERRAINS AND VIRTUALLY INACCESSIBLE LOCATIONS. OUR EXTENSIVE FIELD EXPERIENCE HAS HELPED US DOMINATE COMPLICATED TECHNOLOGIES SUCH AS GROUND PENETRATING RADAR, MAGNETIC GRADIOMETRY, ELECTRICAL RESISTIVITY TOMOGRAPHY, PULSE INDUCTION METAL DETECTION, THERMAL IMAGING, DRONE SURVEYING, AND EVEN SATELLITE BASED REMOTE SENSING TECHNOLOGIES.
OUR SURVEYS ARE PROFESSIONAL AND DISCREET AND CAN BE TAILORED TO THE REQUIREMENTS OF EACH LOCATION. PLEASE CONTACT US DIRECTLY WITH THE SPECIFICS OF YOUR PROJECT TO DISCUSS HOW WE CAN BEST SERVE YOU.
Ground Penetrating RadarGPR IS A VERY POWERFUL TOOL IN LOCATING AND IDENTIFYING UNDERGROUND TARGETS SUCH AS CAVES AND TUNNELS, SEDIMENT LAYERS, MINERAL DEPOSITS, AND BURIED OBJECTS UP TO 25 METERS DEEP. GPR WORKS BY SENDING RADIO WAVE PULSES INTO THE GROUND AND THEN READS THE SIGNALS THAT ARE BOUNCED BACK. THESE RADIO WAVE PULSES REACT TO DIFFERENT OBJECTS DEPENDING ON DENSITIES OF MATERIALS PASSED THROUGH AND THE REFLECTIVE OR ABSORPTIVE NATURE OF SUBTERRANEAN MATERIALS. THE SPLIT IMAGE ON THE LEFT IS OF A STORM DRAIN THAT IS APPROXIMATELY FIVE METERS BELOW THE SURFACE. (EACH SIDE IS THE SAME IMAGE WITH DIFFERENT FILTERS APPLIED.)
Magnetic GradiometryA MAGNETIC GRADIOMETER READS MINUTE CHANGES IN THE STRENGTH OF THE EARTH'S MAGNETIC FIELD TO PRODUCE A MAP OF SUBSURFACE ANOMALIES. FOR EXAMPLE, A BURIED OBJECT WILL DISTURB THE MAGNETIC FIELD, CHANGING IT SLIGHTLY. THE SAME IS TRUE WITH A CAVE OR TUNNEL. THE VOID WILL DISTURB THE MAGNETIC FIELD. A MAGNETIC GRADIOMETER WILL PICK UP AND MAP THE IDENTIFIED ANOMALIES.
Electrical Resistivity Tomography ERT IS A TRIED AND TRUE PROCESS WHERE ELECTRODES ARE PLACED IN THE GROUND AND AN ELECTRICAL CURRENT IS PASSED BETWEEN THEM. DEPENDING ON THE RESISTANCE THE CURRENT RECEIVES AS IT TRAVELS UNDERGROUND, YOU CAN DETERMINE THE PRESENCE OF SUCH ANOMALIES SUCH AS CAVES OR TUNNELS, WATER, MINERAL DEPOSITS, OR BURIED METALS SUCH AS A TANK, PIPE LINE, OR EVEN A TREASURE CACHE AT DEPTHS TO 300 FEET OR MORE.
Pulse Induction Metal Detection PULSE INDUCTION METAL DETECTION TECHNOLOGY HAS SEEN CONSIDERABLE AND EXCITING ADVANCES IN THE LAST FEW YEARS. WE USE THE MOST ADVANCED DETECTORS ON THE MARKET TODAY SUCH AS THE EZ PULSE PRO AND THE LORENZ DEEPMAX THAT CAN REACH LARGE METAL TARGETS UP TO SEVEN METERS DEEP.
Thermal ImagingTHERMAL IMAGING CAN BE USED ON THE GROUND OR IN THE AIR VIA A DRONE TO IDENTIFY AREAS OF VARYING TEMPERATURES. HIDDEN STRUCTURES OR CAVE OPENINGS CAN BE LOCATED DUE TO THE FACT THAT THEY RETAIN HEAT DIFFERENTLY THAN THEIR SURROUNDINGS. THE IMAGE TO THE LEFT IS OF A CAVE OPENING. IT IS WARMER INSIDE THE CAVE THAN THE SURROUNDING ROCKS.
Aerial Drone ImagingON SITE AERIAL IMAGING WITH A DRONE PROVIDES A BIRD'S EYE VIEW OF THE TOPOGRAPHY AND CAN HELP IDENTIFY THE GEOLOGICAL AREAS OF INTEREST SUCH AS CAVE OPENINGS, FRACTURE ZONES, MINERAL RICH SOILS, OLD ROADS OR PATHS, OR EVEN ABANDONED STRUCTURES THAT CANNOT BE SEEN FROM SATELLITE IMAGERY, AND AVOID EXTENSIVE ON-GROUND SEARCH TIME.
Remote sensingREMOTE SENSING WITH SATELLITE DATA AND IMAGERY (NMR) CAN BE USED TO PRECISELY SURFACE- LOCATE "MACRO" TARGETS (SUCH AS OIL/GAS FIELDS) OR “MICRO” TARGETS (SUCH AS HIDDEN TREASURE CACHES, CAVES, TUNNELS, ETC.) IN GEOGRAPHIC AREAS SPECIFIED BY OUR CLIENTS. TARGET DEPTH DETERMINATION IS AN ADDED FEATURE OF THE TECHNOLOGY. ADDITIONAL TECHNOLOGIES SUCH AS, MULTI-SPECTRAL IMAGING, AND LIDAR CAN PENETRATE THE EARTH'S SURFACE AND POTENTIALLY IDENTIFY MINERALS, METALS, WATER, AND OTHER SUB-SURFACE OR SURFACE ANOMALIES. ONCE AREAS OF INTEREST ARE IDENTIFIED, PRECISE ELECTRONICS-BASED GROUND SURVEYS ARE PERFORMED TO PINPOINT THE TARGETS BEFORE COSTLY EXCAVATION BEGINS
