Overview

The total station data should report each surveyed target in terms of “Northing, Easting, Elevation.” This coordinate space has a direct translation to the X, Y, Z coordinate space used by Previzion and Maya. The translation is as follows:

• Northing = X axis
• This is the front facing axis in Previzion
• Easting = Z axis
• This axis points to the right of the X-axis (aka, ‘northing’)
• Elevation = Y axis
• This axis points up
• This defines a Y-up coordinate system

Translating Coordinate Spaces

When converting from the survey coordinate system of: (Northing, Easting, Elevation), flip the second and third values.

In other words, easting should be the Z value and elevation should be the Y value.

In the world of surveyors XYZ has a different meaning.  When looking at a blueprint from overhead:

• X – is side and side
• Y- is front and back
• Z- is up and down, coming out of the paper
