What Is Hydrographic Surveying?

Hazel Digital Media Admin - Tuesday, April 01, 2014

Although the practices and principles of Hydrographic Surveying have been around for a long time, the term itself – and the professional trade – are fairly recent. Mariners have always needed to know how deep the water is, and so in this way, there's nothing new about Hydrographic Surveying. However, the methods of the olden days were much more crude compared to today's. And the technology of the present allows for more accurate data than ever before.

So just what exactly is Hydrographic Surveying?

Essentially, it's a science that attempts to provide as much information as possible about underwater surfaces. With the use of hydrographic surveying, one can “see,” as it were, the ocean floor. And given today's advanced technology, this practice provides data on water depth, tide level measurements, and even the sea floor material for a given area.

If you live near the water, there's a good chance that hydrographic surveying may apply to your industry. Here at Surveying Consultants, being based out of the Lowcountry, we've had the privilege of providing hydrographic surveying data for a wide range of varying businesses and individuals.

For any individual or organization who spends a lot of time on the water, hydrographic surveying provides a number of benefits. It is important for anyone on a vessel to know the precise location of shallow depths, in order to navigate through hazardous areas.

Furthermore, knowing what type of material the sea floor consists of is critical when anchoring, pursuing underwater construction (such as pipelines), or perhaps just knowing what types of fish reside where. Perhaps you're a waterside homeowner, looking to build a dock from your backyard: hydrographic surveying can be imperative to this task.

Hydrographic surveying is typically achieved through great use of Sonar, which utilizes sound waves to figure out depth, as well as identify underwater objects and obstructions. Sometimes, light detection is used for more intricate shorelines. Our raw data is then processed and presented to you in a way that is succinct and understandable.

Also known as Maritime Cartography, hydrographic surveying has wide reaching applications for widely-varying individuals. If you find yourself, for whatever reason, needing to obtain an intricate and detailed “map of the sea,” Surveying Consultants is here to help.
