OpenStreetMap 開放街圖
A bit over a year ago I started uploading weekly dumps of the GPS traces from my company's fleet. I've uploaded a bit over half a gigabyte of data since then, or 20,000 to 50,000 points per week, and party render thinks it looks like this:
python render.py -d .. -g none -r 1000 --pos=-32.901318,117.776609
I trace over bits and pieces now and then, but I'm not doing much. I was just wondering whether anyone else is mapping in rural Western Australia and finding these traces useful?

Hi Sam. It's cool that you have all this GPS data. Looks like it covers a massive area centred around Perth. I just picked a spot, downloaded the GPS points and quickly found some roads which needed adding. Pretty useful I'd say!

Thanks Harry! It is centred around Perth indeed; this is where all the vehicles are based. They go out for 10–14 day swings, taking GPS positions every ~30s.
Did you notice my tracey subterfuge with a big empty circle around the Perth metro area?! I get the data in massive clumps of nmea files, and process them with gpsbabel using
-x radius,distance=20K,lat=-31.995815,lon=115.73512,nosort,excludeI wish I had more time to map things, but it's hardly a central part of my employment... :-(

GPS track is bliss, really. I wish some company here, in Russia upload this amount of data - since some areas stil doesnt have Bing imagery, GPS is only way to know if there is road here.
So thank you for data, they definitely useful for OSM.
