Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] figure 1 Shown is a schematic diagram of the three-level index structure of the chart database with the three-level index structure. This nautical chart database with three-level index structure includes several nautical charts, and the nautical chart database has a nautical chart index 1, and the nautical chart index 1 includes each nautical chart (sea chart) figure 1 ,ocean figure 2 , chart 3, ..., chart n), the index information of the chart includes the coverage area information of the chart. From the chart index 1, the charts that meet the query conditions can be found. At the same time, each chart has its own internal index, and the found objects inside the chart can be further searched through the internal index of each chart. Th...

Abstract

The invention relates to a chart data index, and in particular relates to a chart database with a three-level indexing structure and a data reading method thereof. According to the invention, a chart index is designed in the chart database; a chart can be retrieved through the chart index; simultaneously, internal indexes of various charts are designed; the internal indexes include object classification indexes and object indexes in the corresponding charts; the object classification indexes and the object indexes of the corresponding charts can be sequentially searched according to classification attributes and characteristic attributes of objects in need of being displayed in a target display area; and thus, the objects in need of being displayed can be located and displayed. By means of the three-level indexing structure, the chart data reading speed can be greatly increased; and thus, the chart display speed is increased.

Description

technical field [0001] The invention relates to a chart data index, in particular to a chart database with a three-level index structure and a data reading method thereof. Background technique [0002] The chart display process involves reading the chart data in the chart database. The chart database includes several charts, and each chart includes a large number of objects of different types, so the chart database involves a huge amount of data. However, due to the lack of design of the chart index and object classification index in the traditional chart database, the reading of chart data is slow and the chart display speed is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a nautical chart database with a three-level index structure and a data reading method thereof, so as to improve the reading speed of nautical chart data. The present invention is achieved like this: [0004] A chart database with a ...
