The invention discloses a method for generating an electronic channel chart based on the
Changjiang River standards, which is mainly based on the
digital channel measurement
data transmission standard of the
Changjiang River, the
digital channel measurement
data verification standard of the
Changjiang River and the electronic sea chart data protection scheme recommended by IHO (International Hydrography Organization), sets up a standardized electronic channel chart
database of the Changjiang River by utilizing advanced
computer network technology, data communication technology and geographic
information processing technology, realizes the measurement and the management for channels over the Changjiang River, the generation of the electronic channel chart and the
automation, integration and networking of the entire release process by means of the generation flow including
data acquisition,
data processing, editing of the channel chart, checking of the channel chart, release of the channel chart and application of the channel chart, and provide, in the form of browser, the latest electronic channel chart service for ships sailing on the Changjiang River, shipping related departmentsand enterprises and public institutions in time. The method has the obvious advantages of normative
data format,
complete data updating mechanism, mature business
system, safe information
protection mechanism, great
advantage in popularization and the like.
