Common mistakes with WGS84 ARC System Zone 4
- Feet entered as metres. WGS84 ARC System Zone 4 is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Looking for a datum shift that isn't there. WGS84 ARC System Zone 4 is defined on WGS 84, the datum Google Earth uses, so no shift is applied. If points are off by tens or hundreds of metres, the data is probably on another grid.
- Points outside the grid's area. WGS84 ARC System Zone 4 is meant for ARC System - Zone 4. Points well outside that area convert with growing error; the converter flags them so you can choose the right grid.
- A local site grid. If every point is off by the same distance and direction, the drawing may be on a local site grid. Calibrate on three or more known control points instead.
