Questions & Answers
BYN files: Frequently Asked Questions
What are BYN files?
BYN (Natural Resources Canada Geoid) is a binary grid format that contains an 80-byte header followed by the grid values. The header defines the south, north, west, and east boundaries and the spacing in arc-seconds, the size of each value (2 or 4 bytes), a scale factor, and a data type field, where 0 means geoid heights, 1 means error estimates, 2 means velocities, and 3 means velocity errors. The values are stored row by row, starting from the northern edge, and from west to east within each row. The number of rows and columns follows from the boundaries and spacing, so the file size equals 80 bytes plus rows times columns times the value size. Cells without data are marked with 32767 in 2-byte files and with 9999 multiplied by the scale factor in 4-byte files. To convert the grid to an image, divide the stored numbers by the scale factor to restore real heights, leave empty cells transparent, and map the range to a grayscale or color scale. The result can be saved as PNG, JPEG, or TIFF, or as GeoTIFF to keep coordinates and exact values. Supported by ArcGIS, GPS-H, FieldGenius, and Hydromagic.
