The SnakeGrid family of products, developed by UCL Business PLC, provides a comprehensive solution to a significant problem in engineering surveying – the design of a coordinate system with minimal scale factor and height distortion even when projects extend for many hundreds of kilometres.


SnakeGrid, enables engineers and surveyors, working on large railways, highways and pipelines projects, to  have a single seamless grid with a scale factor distortion less than a few parts per million along the whole project and for several kilometres on either side. It also solves the added problem of making reductions to sea level or any other standard reference height, in projects with significant height range.


SnakeGrid gets around problem faced by engineers and surveyorsor, by developing a grid that keeps scale factor at unity along a trend line that follows the project in plan and height.
