Colorado North (NAD83(2011), ftUS)

EPSG:6430 (NAD83(2011) / Colorado North ftUS)

FieldToCAD transforms localized ground coordinates to Colorado North NAD83(2011) State Plane (US survey feet) using Lambert Conformal Conic projection with EPSG:6430 parameters, entirely in your browser.

Datum: NAD83(2011)
Projection: Lambert Conformal Conic
Units: US survey feet
Central meridian: -105.5 deg

Colorado North uses a Lambert Conformal Conic projection with standard parallels at 40 deg 47 min and 39 deg 43 min N, central meridian 105 deg 30 min W, and false easting/northing of 3,000,000 / 1,000,000 ftUS.

Combined scale factor at your project location combines the grid scale factor from the LCC projection with the elevation factor from ellipsoid height. Use the Inspector auto-CSF tool with your project elevation and GEOID18 separation.
