Plumb surveying utilizes modern and cost effective office and field equipment including High Definition Surveying (HDS) System. Field crews are equipped with 4 x 4 Survey vehicles and 4 x 4 all terrain vehicles. Drawings are made in Auto CAD Civil 3D 2011 with the ability to electronically files via the internet transfer drawing files.
A 3D laser scanner is an advanced type of survey/measurement instrument that is used to remotely measure surface geometry of sites and structures with extraordinary completeness, accuracy and speed. Unlike traditional surveying tools that are used to record certain, selected points manually within a scene, a 3D laser scanner automatically blankets the scene with hundreds of thousands or even millions of closely spaced point measurements. We provide services that enable customers to capture any objects and scenes from the real world and to produce 3D models accurately, quickly, easily, and economically.
Due to the growing interest in updating geodata mainly 3D data and cadastral data as basis for GIS and mapping applications there is a demand for a fast and efficient surveying method that combines data acquisition with additional information such as images, orthoimages, 3D-models of buildings and infrastructure, and elevation models. One possibility for such a fast and efficient capture of georeferenced data is the use of UAV systems (Unmanned Aerial Vehicles).
Global Positioning System
GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the users exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the users position and display it on the units electronic map.
Current surveying equipment technology is centered on collecting data and using data in conjunction with various survey instruments and systems. The data collection software can perform coordinate geometry computations and other calculations. Measured values captured by the total station, GNSS receiver, or digital level can be displayed numerically and/or graphically and recorded in the data collector and later downloaded to a computer. Stakeout computations are also generated in the data collector and sent to the total station or GNSS receiver. Stakeout information can be numerically and/or graphically displayed.
Ground Penetrating Radar
GPR sees widespread use for locating buried pipes and cables. The unique ability of GPR to detect non-metallic as well as metallic structures provides a distinctive locating capability. GPR can be deployed in simple locate and mark mode for rapid on-site solutions. Whether carrying out Subsurface Utility Engineering (SUE) or controlling excavation in complex areas, GPR surveying and mapping provides unmatched capability for defining subsurface infrastructure.
A Total Station is a modern surveying instrument that integrates an electronic theodolite with an electronic distance meter.
A theodolite uses a movable telescope to measure angles in both the horizontal and vertical planes. Traditionally they are manual instruments that come in two types transit, which rotates in a full circle in the vertical plane, and non-transit, rotating in a half-circle.
