Note: As of October 2019, this report has been superseded by IOGP Report 373-26: Coordinate transformation in the Gulf of Mexico.
IOGP Report 373-17
Study the current general purpose coordinate transformations used to change coordinates between WGS 84 and NAD27 within the Gulf of Mexico.
Early operations offshore in the Gulf of Mexico were referenced to the NAD27 coordinate reference system (CRS). NAD27 is still considered to be the operational CRS for E&P activities in the Gulf of Mexico. For navigation most operations in the area use a global navigation satellite system, and in particular the Global Positioning System (GPS). The coordinate reference system for GPS is WGS 84. This guideline is intended to document current general purpose coordinate transformations used to change coordinates between WGS 84 and NAD27 within the Gulf of Mexico.
