Mapping Projections

Community base mapping and legal surveys are referenced to the Modified 3º Transverse Mercator mapping projection. The 3 degrees indicates that the projection covers a zone of 3 degrees of longitude. The modified means that in some cases the width of the zones is modified by ½ degree to avoid a zone boundary in a city or town. The scale factors in each MTM zone varies from 0.999900 at the central meridian values greater than 1.0 on east and west outer portions of the zones.

Across Newfoundland and Labrador there are 6 zones numbered 1 through 6.

Resource base mapping and several resource Geographical Information Systems are referenced to the Universal Transverse Mercator mapping projection. The UTM is a world wide military mapping projection that covers zone of 6 degrees of longitude. The scale factors in each UTM zone varies from 0.999600 at the central meridian values greater than 1.0 on east and west outer portions of the zones.

Across Newfoundland and Labrador there are 4 UTM zones numbered 19, 20, 21 and 22 (from west to east). Click UTM Zones to view a diagram showing the coverage of the 4 UTM zones.
