Mapping Stumbled Stations with MapPoint and Stumbverter

NetStumbler's Native Data Files

What you have in your hands at the end of a wardrive is a log file of all the stations detected by NetStumbler while you were out driving around. My description of log file data gets pretty technical in spots, so you can skip anything that seems outside your interests. Not all of it is equally useful. Most of what's in the log is pretty obvious, but I want to be as complete as possible, since I haven't seen the whole thing documented in any one place.

For its logs, NetStumbler generates binary files with a .NS1 extension. Netstumbler's author Marius Milner has not documented the binary format of the .NS1 file, which is ok, since I think we'd all prefer that he be adding features to NetStumbler. (He may also prefer that we not write software that manipulates .NS1 files directly, so that he can change the format as NetStumbler evolves without breaking other people's code.) The .NS1 files can be merged together, or loaded back into NetStumbler for examination by selecting File|Open and entering the file name, but there isn't anything else you can do with them directly. To somehow process the data that you collect on a wardrive, you must export a log file to a text file, as I'll explain shortly.
