The meridians and parallels of Modified Stereographic projection are generally curved, and there is usually no symmetry about any point or line. There are limitations to these transformations. Most of them can only be used within a limited range. As the distance from projection center increases, meridians, parallels, and shorelines begin to exhibit loops, overlapping, and other undesirable curves. A world map using the GS50 (50-State) projection is almost illegible with meridians and parallels intertwined like wild vines.
All meridians are normally complex curves, although some may be straight under certain conditions.
All parallels are complex curves, although some may be straight under certain conditions.
Graticule is normally not symmetrical about any axis or point.
Scale is true along irregular lines, but the map is usually designed to minimize scale variation throughout a selected region.
