GM1 AIS.TR.200(b) General ED Decision 2020/008/R ACCURACY — RESOLUTION (a) The resolution of the data contained in the database may be the same or finer than the publication resolution. (b) Stating that resolution needs to be commensurate with the accuracy means that digital data needs to have sufficient resolution to maintain accuracy. Typically, if an accuracy of .1 units is needed, then a resolution of 0.01 or .001 units would enable a data chain to preserve the accuracy without problems. A finer resolution could be misleading as one could assume that it supports a finer accuracy. This factor range of 10 to 100 between accuracy and resolution is applicable regardless of the units of measurements used.
