The Research of Chart Database Scale Classification Based on the Demands of Navigation
摘要
Abstract
The manufacturing status of nautical charts and charting technology based on database are introduced.Aiming at scale classification of chart database construction for nautical chart production,according to the common rules of selecting sample paper charts,the chart load is calculated.It shows that the values of chart load affected greatly by the terrain and human factors.Defining an ideal sea area which only contains soundings,by determining the relationship between the chart load and the soundings interval,and refering to the minimum of the paper chart sounding interval,considering the demands of scale classification for navigation,the scale classification solution of chart database is finally determined.关键词
