摘要

Approximately 50% of the sounding data shown on US NOAA nautical charts is pre-1940, collected by antiquated lead-line soundings and wire drags. Even the 500,000 square nautical miles of the most navigationally significant EEZ waters would require 167 years to survey. Crowdsourced data can significantly augment authoritative geodata bases and provide answers to critical mapping deficiencies. The challenge in the marine geospatial sector is to ensure the reliability of crowdsourced data by managing and structuring the process to ensure that it can be confidently relied upon as useable and accurate. SURVICE Engineering and CARIS have developed the ARGUS system as one such reliable process.
