Zones 4 and 5 in NAD83(CSRS)v6

MTM NS 2010 uses NAD83(CSRS)v6 at epoch 2010.0, with zone 4 registered as EPSG:8082 and zone 5 as EPSG:8083. Their central meridians are 61°30′ W and 64°30′ W. The false eastings are 24,500,000 m and 25,500,000 m.

Keep the full easting prefix. At NSCM 210111, Ketch Harbour, the published zone 5 values are E = 25575120.413 m and N = 4928410.503 m. This converter expects easting before northing, even when a station report lists northing first.

Different prefixes identify different systems

ATS77 uses eastings around 4.5 or 5.5 million; the older NAD83(CSRS) epoch 1997.0 layout uses 14.5 or 15.5 million. Removing 20 million from a 2010 easting does not perform the datum transformation. Select the actual system recorded in the survey.

The MTM projection is checked against published NSCRS monuments to below 1 mm. Conversion to the generic WGS84 GPS output uses a 2 m datum approximation; no velocity or epoch propagation is applied.

For a UTM result, select NAD83(CSRS)v6 / UTM and confirm the zone. MTM zone 4 is not UTM zone 4. Source and monument coordinates: Nova Scotia Coordinate Referencing System.

Frequently asked questions

Why is the easting about 25 million metres?

Nova Scotia includes a datum and zone prefix in the false easting. Keep it intact so the numbers identify the intended MTM NS 2010 zone.
