Hydrographic surveying is undergoing fundamental changes in measurement technology. The advent of
satellite positioning systems, multibeam and multitransducer acoustic systems and sophisticated data
processing systems have drastically changed the way hydrographic surveys are conducted. With these
advanced technologies, the Canadian Hydrographic Service and contractors can now collect data with
higher precision and quality. It is therefore necessary to update the standards taking into account these
technological advancements.
The required positioning accuracy in previous versions of SSO was largely based on the practical limitations
of draftsmanship at a given scale. Automated data management allows data to be presented at any scale.
Therefore, the accuracy requirements for positions in this standard are a function of the errors contributed
by positioning and sounding systems to some degree, but is mostly based on the perceived accuracy
requirements of the user.
