CID File – What is .cid file and how to open it?
CID File Extension
Navigator Chart Image Description File – file format by Navigator Software
CID is a file extension for a Navigator Chart Image Description File, a type of vector image file format developed by Navigator Software. It is used to store nautical charts and other maritime data in a compressed format.
CID File: Navigator Chart Image Description File
A CID file, or Navigator Chart Image Description File, is used to store the data and formatting specifications for a nautical chart or map created using the navigation software Navigator. It contains information such as the chart’s title, scale, orientation, symbols, and other navigational details. CID files enable the seamless display and manipulation of charts within the Navigator program, allowing users to plan routes, mark waypoints, and navigate effectively.
Technical Specifications and Uses
CID files are text-based files that follow a structured format. They contain various sections, including header information, chart data, and metadata. The header section includes details such as the file version, chart title, and author. The chart data section stores the actual chart image as a series of encoded lines and points. The metadata section provides additional information about the chart, such as the date of creation, projection parameters, and geodetic datum used. CID files can be used not only within the Navigator software but also imported into other navigation and mapping applications. They facilitate the exchange of chart data and ensure that charts are displayed and interpreted consistently across different systems.
CID File Basics
CID files are associated with Chart Navigator, a nautical navigation program designed for marine navigation. These files contain geographical chart information, such as latitude and longitude coordinates, navigational aids, and other data needed for marine navigation. They are typically created using the Chart Navigator software.
Opening CID Files
To open a CID file, you will need to have Chart Navigator software installed on your computer. Once installed, you can open the CID file by double-clicking on it or by selecting “File” > “Open” within the Chart Navigator software. The file will then load into the software, allowing you to view and edit the chart information. In addition to Chart Navigator, some other third-party applications, such as OpenCPN, may also be able to open and view CID files.
CID File Format
The CID file format, short for Chart Image Description File, is a proprietary data format created by Navigator Software. It serves as a vector graphics format specifically designed for storing and exchanging nautical charts and maps. CID files contain detailed cartographic information, including chart linework, symbols, text annotations, and other relevant data necessary for accurate navigation. This format enables the efficient storage and manipulation of complex chart data, making it ideal for electronic chart display and information systems (ECDIS) in the maritime industry.
Applications of CID Files
CID files are widely used in marine navigation systems, providing a reliable and comprehensive digital representation of nautical charts. They offer several advantages over traditional paper charts, including the ability to zoom, pan, and effortlessly update chart data. ECDIS systems that support CID files allow mariners to access a real-time, interactive view of their surroundings, enhancing situational awareness and navigation safety. Additionally, CID files can be easily integrated with other maritime software and applications, facilitating data exchange and automation of navigation-related tasks.
