GPS and the Engineer The Global Positioning System (GPS) is a space-based positioning system. It can be used in place of traditional surveys to determine the position of features quickly and accurately. While hand held GPS receivers can be accurate to 1-15 metres, survey-class receivers can measure relative positions accurately to 1-2 centimetres horizontally and 3-4 centimetres vertically -- engineering grade positioning. Not only is GPS accurate, but faster than conventional surveying. While traditional surveyors must traverse or level between intervisible points, GPS can measure any point within a 15 kilometre radius almost instantly. Although GPS is fast and efficient, care must be taken to ensure quality results. As with engineering, a wide spectrum of knowledge and procedures, are essential to the delivery of a suitable product. While GPS is an important tool to surveying, it does not entirely replace conventional methods. Everest Geodetics is also widely experienced in traditional surveying techniques. Everest Geodetics and the Engineer Engineers often have requirements for surveys, either set out by project specifications, or simply due to the nature of the project. Everest Geodetics can provide both GPS surveys and conventional control to meet these needs. If you have a project with spatial needs, but are not sure how to proceed, Everest Geodetics can provide technical and professional survey expertise to your company. Services that Everest Geodetics can provide to the professional engineer: horizontal and vertical control surveys project specifications and consulting geotechnical support -- positioning boreholes, borehole layout construction layout -- grades, allignment, hardware (pipelines..) etc. transportation -- project control, layout mapping support -- photogrammetric control for aerial mapping As we are highly knowledgeable in datums, coordinate systems and transformation techniques, Everest Geodetics can assure that the correct product is delivered. The Ministry of Transportation requires that surveyors engaging in control surveys be qualified through their RAQS system. Everest Geodetics is pre-qualified for the GPS Control specialty with MTO. If you are bidding on MTO work that has a survey component, Everest Geodetics can round out your proposal requirements.
