The P2/94 format for the exchange of raw positioning data is recommended by UKOOA for general use
in the Oil and Gas, Exploration and Production industry.
The format is not mandatory and operators may adopt different format standards in a particular
situation where to do so would maintain an equivalent level of quality and performance.
P2/94 has been developed in response to recent and  increasing reliance on differential GPS positioning
for offshore surveying.  It is based upon and may be considered as an extension of it's forerunner,
P2/91,  which caters especially for the positioning data exchange requirements of modern seismic
surveys.  It may, however, be used for any applicable kind of positioning data.  The aim in developing
P2/94 was to add formatting standards for all the parameters needed to re-construct positions based
upon DGPS observations while making minimum changes to existing P2/91 records. The intention was to
make it possible for operators who do not require to use raw DGPS data to continue using existing
software which could simply ignore the additional DGPS records.  However, operators should note that
in the process of consultation with prospective users, a number of small improvements to the original
P2/91 format have been identified and included.
