GPS Visualizer now supports NS files
Posted: Thu May 06, 2004 8:34 am
GPS Visualizer, my free on-line mapping tool, now supports NetStumbler log files. You can upload raw .ns1 binary files, text summaries, or full text logs. GPS Visualizer's output is in the form of SVG drawings, so you'll have to have Adobe's SVG Viewer plug-in installed in your browser.
Those of you outside the U.S. may be especially interested in this, because there are street-level maps available as backgrounds for Europe, unlabeled but very accurate street maps and topo maps for Canada, and 30m Landsat imagery for the entire world. (If you are in the U.S., you can also use TerraServer aerial photos and topo maps, as well as TIGER political maps.)
Here's an example (a screen shot) of the output:
Note that "open" access points are colored red while WEP-enabled ones are green; also, the sizes of the markers vary according to the signal-to-noise ratio. But both of these features -- WEP colorization and point resizing -- can be turned off. You can also choose to only plot points, or only tracks; the sample graphic shows both, and frankly, it can get a little messy, even after you move the labels around. (Speaking of messy, if you have a LOT of access points in your log, you may even want to turn off waypoint labels and descriptions.)
Here's the URL: http://www.gpsvisualizer.com/map?form=wifi (This is a special version of the input form designed for wardriving logs.)
By the way, if you have non-wardriving GPS files laying around (GPX, OziExplorer, etc.), of course GPS Visualizer can draw those too. Just use the standard form instead of the special "wifi" one so you have more options available.
