This template provides a coordinate transformation between DEVCO coordinates (“DEVCO Grid”) and commonly used coordinate systems in Nova Scotia using a 7 parameter Helmert transformation. Due to the movement of the North American tectonic plate they might differ from current values by roughly 1 meter. The sigma is only valid for the Helmert transformation used in this template.

#1194  East | Long | λ North | Lat | φ  
DEVCO meter σ 0.14 m
DEVCO feet σ 0.46 ft
MTM Z 4 ATS77 σ 0.14 m
UTM 20 T WGS84 σ 0.27 m
MTM Z 4 NAD83 (original)  σ 0.17 m

The template must not be used to convert between ATS77, WGS84 and NAD83. Please use the Nova Scotia Coordinate Transformation Web Application.
