The BSB Reader provides FME with access to data in the Maptech BSB Nautical Chart format.
Overview
The Maptech BSB Nautical Chart format is commonly used to store Raster Nautical Charts (RNC) in *.kap files.
Each of these files consists of two parts
- an ASCII header, containing data pertaining to the raster (the most important of which are the color table and the reference points, or ground control points [GCPs]);
- binary data, which uses a patented run-length encoding algorithm to store contiguous pixels efficiently.
Reader Overview
The FME considers a single BSB file to be a dataset.
FME Raster Features
FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. The topics below describe how FME processes raster data.
BSB only supports rasters with a single UInt8 band that has a RGB24 palette.
