Hydrographical Surveys, as the name suggests, are the water based equivalent of Land Surveys. They can be surveys of water courses, open water, in-shore or off-shore. Like Land Surveys they depict topography or land form but of the river bed, sea bed, lake bed and associated features – river bank & flood plain.
At Invar Mapping we undertake a variety of in-shore Hydrographic Surveys for a variety of clients and industries.
Any format provided; cross sections, long sections and 3D models etc.
