Land Surveying Equipment

GPS Survey Systems
This system allows us to utilize cell phone and Bluetooth technology for communication and a network (eGPS) covering the Southeast United States for positioning. The reference stations replace the base and the cell phone technology allows the system to jump from station to station which means we can continue surveying without any distance limitations. This system achieves sub-centimeter accuracies. In addition, the equipment is less cumbersome – lightweight with no cabling. We also have the use of GLONASS and SBAS satellites in addition to the US satellites which limits downtime from lack of satellite reception. For our client, this means that we can provide greater efficiency without losing accuracy. Land & Sea Surveying utilizes the Ashtech/Magellan RTK GPS system for land-based surveying and in conjunction with our hydrographic survey system.

Underground Utilities

RD8100 Cable, Pipe and RF Marker Locator

  • Powerful tool that helps operators pick out their target line from others nearby. With CD you can locate your utility quickly and eliminate wasted time
  • RD8100 is the most advanced locator range
  • Contains unique range of 5 custom manufactured, precision ground antennas
  • Current Direction and iLOC combine with the versatile Tx Transmitter range to deliver highly responsive locates even in tough conditions.
  • Integrated GPS and usage-logging options automatically generate data for reports
  • In-house quality and safety audits to promote best working practices
  • GPS equipped RD8100 locators automatically log key locate parameters every second
  • Power Filters to pinpoint and discriminate between power cables
  • Save up to 1,000 survey measurements, capturing utility depth, and send to a mobile device using Bluetooth
The RD8100 can passively detect the electromagnetic fields from live AC power or radio signals travelling along some conductive utilities. It can also be used in conjunction with a transmitter connected directly to accessible, metallic pipes, risers, or tracer wires. A current is sent through the pipe or tracer wire at a specific frequency and the resulting EM field can then be detected by the receiver. If access directly to the utility is not possible, we can send tone via induction, however this lessens the accuracy of the location. The ability to locate depends on a variety of factors including access to the utility, conductivity, grounding, interference from other fields, and many others. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors.

GPR (Ground Penetrating Radar)

Ground Penetrating Radar, GPR is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures.
