MTM Notes

The following image shows the MTM zones as used by this tool for the eastern portion of Canada. Starting with zone 14, things are regular all the way west to zone 32. I believe the zones here match the zones in NRCan's GSRUG online tool (Feb 2008 version, there are differences with earlier versions). The triangles show the position of the reference meridian and the zone number.

This page was generated with GPS Visualizer, using these tracks as input, and the following options: width=1100, fullscreen (?), trackOpacity=100, trackWidth=1, waypointStyle=smallTriangles, permanentLabels.

There are two discontinuities in zones, which can be grouped as follows:

To cover problem cases, where the MTM definitions here don't match your needs, the reference meridian can be explicitly provided when converting to/from MTM. Right now, the false easting cannot be changed, but if there is need, I could add this too. I don't think MTM makes sense on water.

Some specific notes:

Other provices do not appear to use MTM zones.
