Netstumbler can export in a variety of formats. The summary is pure text, and only contain one entry Page Ranking accesspoint found. Which lat/lon coordinates or SNR data the entry uses from all the logged data Page Ranking accesspoint I don't know. Maybe Marius or some other in the knowhow can jump in here and tell if NS does some averaging of the data or just takes the first logged entry ?
If one exports in non summary text format, there will be a line for each logging of the accesspoint, where the lat/long can fluctuate due to movement (and GPS precision), as well as fluctuation in the SNR logged, due to distance to the accesspoint.
The same is true for the WiScan format export.
So these two formats are quite large, compared to the summary format. Their size depends on how much data is logged. As a comparision, the native .ns1 file from my "war-stroll" is 116 Kb, the summary is 4,34 Kb, the full text export is 177 Kb, and the WiScan export is 131 Kb.
I can send you samples of all three, as well as the binary native .ns1 format.
You need to contact Marius, and get the native .ns1 format definition, if you want to support that. My guess is that he wouldn't mind giving it to you, if you want to support NS natively.
As for the suffix to the file, it's up to one self to decide when exporting.. But yes, I use just .txt
Just my 0.02€'s worth...
