This effort appears to be stalled or dead, but their source code and documentation (while extremely difficult to parse) was helpful.

cGPSmapper-created maps served as the source for this software effort. Stanislaw Kozicki, creater of cGPSmapper at, who has made it possible for the average user to create IMG files.

Dont hesitate to write.ĭisclaimer The information contained in this document was gathered from a combination of the sources listed in the Acknowledgements section, from personally created IMG files and IMG files that were freely available without usage restrictions. My goal is to address the latter, in the hopes that more people will be motivated to do as I haveand possibly contribute to this effort in the process. There are fewer, however, who share their code, and fewer still who share their knowledge. What I quickly learned in the area of IMG parsing was that there are quite a few folks in the know, many of whom share applications with the Garmin community. I also like to share what I know with other, motivated people. Motivation Im a tinkerer, which means I like to look under the hood for its own sake, and it was only natural that Id be intrigued by the file format used by my favorite GPS manufacturer. It will be necessary to read the entire document from beginning to end. Error!

Once all the coordinate deltas have been calculated, they, like the first point, must be left-shifted by 24 bits_per_coord for the level containing the subdivision to obtain the final coordinate deltas.NET Subfile. 25 Highway Records, Exit Records and Highway Data Records.
