test-precision.fmwThe idea is around one to be able to maintain a “grid”/coordinate precision for geometry handling within a workspace. Using certain transformers introduces back a higher precision => re-introduces the limitations of floating points that we have currently in FME. Let’s say, rounding the coordinates, or using a a source with a certain precision + doing a spatial intersection (lines, areas) removes the rounding and mixes rounded coordinates, where we have not intersected for instance, with higher precision where intersection happened. Attached a workspace to mimic the issue. Rounding again coordinates will fix the problem on this small example, but the problem can be bigger with higher amount of geometry, trying to maitain shared boundaries, etc. Rounding will also be a be random to closest coordinates and can create small difference in coordinates of features sharing same end points, boundaries, etc.
