CHS is a world leader in the adoption of hydrographic survey technology, as well as in research and development. With responsibility for charting the world's longest coastline (243,792 kilometres) as well as 6.55 million square kilometres of [[continental shelf]] and territorial waters (second largest in the world), including extensive inland waterways such as the [[St. Lawrence Seaway]], CHS maintains a world-record inventory of more than 1,000 published charts. As such, the organization was an early adopter of single-beam sonar, radio-navigation positioning systems, and computer processing and storage.

The joint Canada-U.S. [[DEW Line]] also necessitated innovative surveying techniques throughout remote northern areas in the [[Canadian Arctic Archipelago]] in support of ships carrying logistics and construction material. CHS is one of the only hydrographic offices in the world with the capability to undertake Arctic surveying, frequently operating in waters that are frozen between 10 and 12 months of the year.

CHS has migrated from single-beam sonar to becoming a major user of multi-beam echo-sounder sonar systems coupled with [[GPS]] to achieve improved survey accuracies. CHS was also one of the first organizations in the world to develop airborne [[LiDAR]] technology, with the LARSEN-500 sensor being used for remote Arctic surveys. Survey data processing software provided by companies such as [[Teledyne CARIS|CARIS]] and Helical Systems, as well as the development of [[Oracle Spatial]] database storage, are spin-offs from research developments at CHS, and are now used throughout the world by other Hydrographic Offices and in the geo-spatial technology industry. CHS demonstrates international leadership in influencing, contributing, developing and adopting: hydrographic standards (S-100); crowd-sourced bathymetry (CSB); satellite-derived bathymetry (SDB); GEneral Bathymetric Charts of the Oceans (GEBCO) and the Seabed2030 project; autonomous hydrographic surface vehicles (AHSV); and the implementation of a Marine Spatial (Hydrospatial) Data Infrastructure (MSDI) as an Hydrospatial Office. CHS is also involved in the successful implementation of new technologies such as: autonomous hydrographic vehicles (surface, underwater, airborne and/or micro-satellites); Maritime Autonomous Surface Ships (MASS); and many more in the context of the emerging hydrographic and hydrospatial artificial intelligence within hydrospatial.
