The Role of Magnets and Magnetic Technology in Hydrographic Surveying
In a recent blog, we talked about the role of magnets in land surveying and mapping; this week, we’re covering the fascinating world of hydrographic surveying. Similar to land surveying, the goal of hydrographic surveying is to determine the depth of the water and the topography of the bottom of say, a lake or ocean. The civil engineers who partake in these surveys use similar tools as they would above ground — in this case, a magnetometer with a magnetic sensor.
Hydrographic Surveying with Magnets
Reasons why an individual or a business may require hydrographic surveying include the following:- To build a dock or boat marina
- Dredging for resources, evidence, or to clear an area
- Planning for waterways (e.g., diverting water)
- Locating wrecked ships
- Locating pipelines
