It is widely used in the fields of mineral resources exploration, water resources assessment and geological disaster monitoring. In recent years, with the rapid development of science and technology, TEM survey equipment equipped with Global Positioning System (GPS) has gradually become the mainstream of the industry, which greatly improves the accuracy and efficiency of mapping.
The transient electromagnetic method obtains information on the conductivity distribution of subsurface materials by transmitting a brief electromagnetic pulse into the subsurface geotechnical body and monitoring its propagation and attenuation characteristics in the subsurface medium. The method is non-destructive, fast and environmentally friendly, and is therefore widely popular in various geological investigations. However, traditional TEM surveys are often affected by changes in terrain and inaccurate positioning of equipment, resulting in inaccurate geological information. At this time, the introduction of GPS is particularly important.
Combined with GPS technology, TEM surveying and mapping equipment can obtain the precise location of the measurement points in real time, thus ensuring the reliability and repeatability of the data. High-precision positioning data can not only improve the efficiency of data acquisition, but also provide great convenience in subsequent data processing and interpretation. In addition, GPS technology can also help researchers to collect data through a wide range of movement to achieve efficient identification and analysis of geological features.
