INCA’s bathymetric surveys experience includes for a wide variety of projects ranging from valley cross-sections for flood plain determination to large dredging and remediation for public ports. INCA’s fully-integrated hydrographic mapping system is designed to meet the Corps of Engineers’ requirement for Class One hydrographic surveys. INCA uses both single-beam and multi-beam sonars, depending on project requirements. INCA uses rigid mounted scanning sonar to provide mapping under piers, wharves, and docks.
