Highlights • We introduce a coordinate system for the atria based on anatomical landmarks.• We construct the coordinates from solutions to Laplace’s equation.• We demonstrate the mapping of both scalar and vector data between different atria.• The coordinate system was used for registration and 2D visualisation of multimodal data.• Patient specific meshes with atrial structures and fibre direction were constructed using just five landmark points.
