NavPak is compatible with many chart formats. The Raster formats that NavPak supports are MapTech, BSB, ChartKit, NDI, NOS, Softchart, RLE, BMP and Geo-Tiff. This includes the free NOAA BSB charts. Also, NavPak supports C-MAP and S-57 Vector charts, which include the free NOAA ENC charts. The TIFF, BMP and RLE formats can be loaded into almost any image editor software. The other formats cannot be updated or manipulated with an image editor. The RLE, TIFF and BMP formats are useful for checking and correcting your own maps and charts and they are very useful for scientific applications. Vector charts consist of instructions to draw the chart. and raster charts are rows and colums of colored pixels.
