The BSB File Format was developed by Maptech, Inc. to describe and store raster image data and associated textual documentation. While it’s capable of representing various mapping and charting formats, it’s primarily used for nautical charts in marine navigation1. These charts are essential for safe navigation at sea. If you’re working with BSB charts, you can load them using the corresponding file extensions (e.g., *.KAP or *.CAP) and even directly from compressed folders. Keep in mind that BSB charts support automatic collar removal for seamless display of chart data2. If you need to work with BSB files programmatically, the GDAL library provides support for reading BSB Nautical Chart files3.
