NAD83 / California zone 3 (ftUS)

Available transformations
to EPSG:5703
EPSG:5703 - NAVD88 height

Selected transformation

Name: NAD83 to NAVD88 height (6)

Method: Geographic3D to GravityRelatedHeight (gtx)

Grid Files: g2003u06.bin

Remarks: Uses Geoid03 hybrid model. See information source for further information. Note: Source CRS is 2D, used in this application of the method as a pseudo-3D CRS.
