Automated technology for creating and updating paper and electronic nautical charts
The article deals with a new automated technology to create and update nautical charts: paper and electronic. It also displays the disadvantages of the existing technology, which has a traditional foundation despite the use of computers. The necessity to improve the technology is substantiated. The authors of the article suggest a concept to solve the issue of applying an object-oriented database of geospatial data in accordance with the international mapping trends and the S-100 Standard.The concept of the object-oriented database, its features and advantages are presented. The proposed framework is implemented in the original technologies for creating and updating nautical navigation charts, bothpaper and electronic, together with the processes that automate the technological cycle according to the algorithms of the developed specialized software. The proposed technological schemes are given in the paper: a) creation of navigation paper maps - in comparison with the existing variants; b) creation of electronic navigational charts - in comparison with the current system; c) timely (weekly) updating of electronic and paper maps. The authors describe theworking stages of original specializedprograms within the software package "Geographic Information System Neva", which is the main software tool used in the cartographic production of nautical charts, are shown.
