SAM Expands Hydrographic Services

November 20, 2013

Surveying And Mapping® has expanded our hydrographic surveying capabilities to enhance the comprehensive set of geospatial services we offer to clients across all market sectors. Our twin-engine, 26-foot aluminum Workskiff, customized specifically for hydrographic operations, provides an ideal platform for surveys of near-shore and inland waters. This boat supports deployment of diverse geophysical technologies including single- and multi-beam echo sounders, mobile LiDAR, real-time 3D sonar, magnetometer arrays, pipeline and cable locators, sub-bottom profilers, side-scan and sector-scan sonars, and inspection class remotely operated vehicles. We are now equipped to meet all of our clients’ hydrographic needs in support of their oil and gas, electric energy, water, environment, and transportation projects. In addition, two new professionals have recently joined the SAM team to help lead our hydrographic surveying effort:
