Mapping accesspoints online and making gifs afterwards.. - Page 2

I would agree MapPoint is quite expensive, although I love every part of it . . . but I ran Streets and Trips for quite some time and must admit it does a damn good job for $30 . . . so for real high quality maps and lots of possibilities you might wanna check it out . . .
good luck

Streets and Trips is US only AFAIK.. The equivalent MS product for Europe is Autoroute UK 2004, which cost 500 Dkr (appr. 80 USD).

But again, gpsvisualizer is free of charge, and I don't need to upgrade the old laptop (Dell Latitude CP. 233 mhz Pentium with 96 Mb ram) I use for my war-strolling to run it.. Just run Thorn's perlscript, connect at a hotspot, and go to Adam's site, make the map, and do a screendump to have it in gif format.

Just like NS, I feel that Adam's site is great value for the price

Just my 0.02€'s worth...

Oh, and another thing: add an initial field called "type," and put "W" in for each point. Without that, when you upload the .csv file, it'll be read as a track file instead of a collection of waypoints.

Sorry, I didn't know about the price hike outside of the US. And I do agree the online platform is nice, I played around with it today.

It took me a while to assemble that from Dutch's exported data, but it's an example of the kind of thing that COULD be done with complete data.

I actually started doing it because I wanted to see how the "summary" points were calculated. It looks like it might try to mark a point near the center of the points it collected from a particular base station, but it's not 100% predictable.

Hot damn!!! This is great !! Gives one the posibility to see exactly where the accesspoint is reachable from. Much more info than what I hoped would be possible to get by using your service.

You used the summary data together with the full export to do this ?

I.E. cleaning up the summaryfile data, and adding the type field with each entry as a W for waypoint, and cleaning up the Full Text export, adding the type field with each entry as a T for track, concatenate the two files into one, and then uploading that file to gpsvisualizer ?

Shouldn't be to hard to adapt Thorn's script to do that in one go, if that is the case..
Added after testing...
I have changed Thorn's script to do the above, but I can't seem to get each accesspoint to show up on it's own track. Did you break down the data, so each accesspoint have it's own datafile ? Or is there a trick here which I'm to dense to see

OTOH by just doing the above, I get a pretty good approximation of the route of my stroll. Going to play with the GPSGATE software mentioned in an other thread, so I can make a seperate track file with the complete route, which then can be overlaid to the map as well. So having a total documentation of where I went physically from my GPS's normal tracker software, as well as Netstumblers loggings with the accesspoints tracks like in your example.
End of addition...

This is great fun, drilling the data down and presenting it

Thanks for giving an old man some fun

Just my 0.02€'s worth....

P.S. Adding to my previous posts P.S: Adam, if you ever get to Copenhagen, holler, and I'll buy you both danish beer, AND dinner

No, there's no trick you missed if you're creating a plain text file. To accomplish that map, I wrangled everything into a GPX file; GPX files, of course, can have different names for each track. (You don't want to have to manage 20 text files for a single NetStumbler log.)

Don't do too much more with Thorn's script, though; I will find a way to make this work in GPS Visualizer. Maybe this weekend.

Done!

Well, I've mostly managed to figure out the binary format, although I've encountered a couple of variations in files from different people, and while I managed to make it work, I'm not sure the duct tape will hold.

Could some more people please send me some .ns1 files? I'd especially like to see some that have the "# Name" (manufacturer, maybe?) field filled in.

Could you give an outline of steps necessary and software used, to make that GPX file.. I've done some searching, and found Topografix website, with EasyGPS and ExpertGPS, are one of those programs necessary to get the data into GPX format ?

At the moment I'm just playing around with adapting Thorn's Perl script, to do something similar. Great way of learning some perl

Looking forward to seeing what you come up with regards to native NS1 file format support.

Just my 0.02€'s worth...

GPSBabel can actually convert to GPX (once you give it a file defining your input format)... but to create that file the other day, I actually just did a lot of really ugly multi-step sorting and search-and-replacing in BBEdit. I wouldn't recommend it.

Well, like I said, I've got it mostly figured out... but I'm not going to declare victory until I've tested it against a few more files. All I have right now is one Dutch sent and a couple I found with Google. Hint, hint: please send me some. Send me some from older versions of NS, if you can; and better yet, send some with that mysterious "Name" field filled in.

(If you're wondering why I don't just make my own files, it's because I don't even have a GPS setup that would allow me to.)

You just need .ns1 files? I can send ya some if u give me ur email or another way of getting them to u . . .

Just e-mail them to the address at the bottom of http://www.gpsvisualizer.com/. (Of course, it'd be nice if you .zip them first!)

Ok, i get off of work in about 5 hours, you will have them in ur box then . . .

adamschneider · 05-03-2004

Okay, I think it's working:

Please test it out and let me know if it doesn't like your files, or if you have suggestions on how the input or output could be improved.
