KAP File – What is .kap file and how to open it?
KAP File Extension
BSB Chart Image File – file format by Maptech
KAP is a file extension for BSB Chart Image Files developed by Maptech. These files contain raster images of nautical charts used in electronic navigation systems. They are typically stored in a compressed format and may include additional information such as chart metadata and annotations.
KAP File Format
KAP files are BSB Chart Image Files, a raster image format used to store geospatial data from nautical charts. Developed by Maptech, KAP files encapsulate high-resolution chart images featuring detailed coastlines, bathymetry, navigational aids, and other information critical for maritime navigation. They are commonly used in electronic chart display and information systems (ECDIS) on board ships and boats.
Features and Uses of KAP Files
KAP files offer several advantages for nautical charting. They provide accurate and comprehensive representations of chart data, supporting the safe and efficient navigation of vessels. The images are highly detailed, allowing users to zoom in and inspect specific areas of interest, such as harbors, channels, or underwater obstacles. Additionally, KAP files can be overlaid with other geospatial data, such as GPS tracks, weather forecasts, or additional nautical information, enhancing the overall situational awareness for mariners.
Using PC Software
BSB Chart View is a free software released by Maptech, designed primarily to open and display KAP files. This program is compatible with Windows operating systems. Once installed, you can open KAP files by simply double-clicking on them, which will launch BSB Chart View and display the chart image data.
Using Online Tools
If you prefer not to install software, you can use online tools to open KAP files. A few options include:
- KAP Viewer: A web-based tool that allows you to upload and view KAP files directly in your browser.
- BSB Chart Plugin for Google Earth: This plugin lets you open KAP files within Google Earth, enabling you to explore and visualize the chart data in a 3D environment.
KAP File Format: Overview
KAP files are raster image files that store nautical charts in a proprietary format developed by Maptech. They are typically used to display charts on GPS navigation devices and other marine electronics. KAP files contain both raster data (pixels) and vector data (points, lines, and polygons) that together represent the chart’s features, such as shorelines, depth soundings, navigational aids, and other landmarks. The raster data provides the visual representation of the chart, while the vector data allows for accurate measurements and calculations. KAP files are highly compressed to minimize their file size, making them suitable for use on devices with limited storage capacity.
KAP File Usage and Compatibility
KAP files are primarily used by Maptech’s own chartplotter software, Cartographer. However, they can also be opened and viewed by other navigation software and utilities that support the KAP file format. Some popular software that supports KAP files includes OpenCPN, Fugawi Marine Navigation, and Nobeltec TimeZero. Additionally, online chart viewing services, such as Navionics and C-MAP, allow users to view KAP files within their web-based or mobile applications. To ensure compatibility with different software and devices, KAP files can be converted to other raster or vector file formats, such as JPG, PNG, or DXF.
