Geophysical Survey
A geophysical survey involves the use of various physical methods to study and understand the subsurface properties of the Earth. This type of survey is crucial for investigating the geological structure, composition, and other characteristics beneath the ground without the need for excavation. Geophysical surveys are employed in a range of fields, including environmental studies, mineral exploration, civil engineering, and oil and gas exploration.
Seismic Refraction/
Reflection Test
Seismic refraction and reflection tests are geophysical methods used to study subsurface conditions, particularly in determining the depth, velocity, and structure of rock and soil layers. These tests are commonly employed in geotechnical investigations, environmental studies, and exploration for natural resources.
Electric Resistivity Test
The Electric Resistivity Test, often referred to as Electrical Resistivity Tomography (ERT) or Electrical Resistivity Imaging (ERI), is a geophysical method used to investigate the subsurface properties of the Earth. This test measures the electrical resistivity of the soil or rock, providing information about the distribution of different materials and their moisture content.
Geologic Mapping
Geologic mapping is a fundamental method in geology that involves the systematic collection and representation of data about the distribution of rock units, structures, and other geological features on the Earth's surface. The goal of geologic mapping is to create accurate and detailed maps that provide a visual representation of the geological characteristics of a specific area.
Ground Penetrating Radar
Topographic Survey
Geodetic Survey
Ground-penetrating radar (GPR) is a valuable tool with numerous applications across various fields. Its importance lies in its ability to provide non-destructive subsurface imaging, allowing for the detection and characterization of buried objects or geological features without excavation.
A topographic survey is a detailed mapping process that measures and records the elevation of different points on a piece of land. This survey captures the natural and man-made features of the terrain, such as hills, valleys, trees, buildings, roads, and water bodies.
A geodetic survey is a type of surveying that focuses on accurately measuring and determining the positions of points on the Earth's surface in relation to a global coordinate system. Unlike topographic surveys that primarily deal with local terrain features, geodetic surveys consider the curvature and shape of the Earth, taking into account its geoid model.
