About SnakeGrid

SnakeGrid is a way of developing low-distortion coordinate systems for large engineering projects – in particular railways, highways and pipelines. For projects extending for hundreds of kilometres, we provide a single seamless coordinate system with a scale factor within a few parts per million of unity all along the route and for several kilometres on either side.

There are many advantages to this approach – no need to switch from one coordinate system to another; no need to make scale factor corrections for the projection or the elevation effect; one single coordinate system for all data sets, allowing easier updating and re-use of survey data; a one-to-one relationship between the design and the ground.

For detailed information have a look at our technical zone, or have a look at the case studies to see what users are doing with SnakeGrid and the advantages it brings them.
