Research, production, and use have entered a new era, which has also pushed navigation automation to a new level. The so-called Electronic Chart (EC) displays chart information and other navigation information on a display, hence it is also known as a "screen chart". The electronic chart and its application environment constitute the electronic chart system Electronic nautical charts are digital products that describe geographic and navigational information of sea areas, mainly involving the ocean and its adjacent land. Detailed description of the shore shape, islands, reefs, shoals, sunken ships, water depth, geology, navigation aids, tidal currents, ocean currents, and other necessary information for navigation. Electronic charts can be divided into two categories according to their production methods: vector electronic charts and raster electronic charts
(1) Vector Charts
Digital charts represented in vector form.
. Each element in a chart is stored in electronic chart data files in the form of geometric shapes such as points, lines, and surfaces, which has the advantages of small storage, fast display speed, high accuracy, and support for intelligent navigation. Users can selectively display different levels of information (such as only displaying water depth points less than 10M) based on their needs when querying the details of any icon in the electronic chart (such as beacons, colors, and periods). The combination of vector electronic charts with other ship systems can provide automatic alarm functions such as warning zones and danger zones. Vector electronic charts are known as "intelligent electronic charts"(2) Raster Charts
A digital chart represented in raster form that forms a single digital information file by scanning a paper chart in one go.
; Reflect the elements in the chart in a pixel arrangement, relying on the eyes to identify navigation elements. Therefore, raster electronic charts are considered to be replicas of paper charts, which contain information such as shorelines, water depths, etc. that correspond one-to-one to paper charts. Raster electronic charts can also be connected to positioning sensors (such as GPS), but due to the limitations of the production principle of raster electronic charts, raster electronic charts cannot provide selective query and display functions (such as querying the features of a certain chart element, or hiding the features of a certain type of chart element, etc.). Raster electronic charts are referred to as "non intelligent electronic charts". At present, electronic charts are mainly based on vector electronic charts, while raster electronic charts are used as supplements in sea areas without vector electronic chartsFunction of testing report:
