They were collected by a nationwide survey over 4 months, covering the country of Swaziland. I experimented with a number of things, including producing tile sets from the data, and making it available for tracing in the HOT Tasking Server.</span></div><div style="color: rgb(0, 0, 0); font-size: 16.363636016845703px; font-family: 'times new roman', 'new york', times,

My company makes an iPhone app that allows users to make on-demand requests for taxis, luxury sedans, and other vehicles. We currently operate in 25+ cities in the United States, Europe, Asia, and Australia.</div>
<div style="font-family: arial, sans-serif; font-size: 13px;"><br></div><div style="font-family: arial, sans-serif; font-size: 13px;">We have GPS traces going back about three years from our drivers, and I am interested in contributing back to the OSM community. I was planning on writing a script to anonymize and clean up our traces and export as GPX files (per instructions here <a rel="nofollow" target="_blank" href="http://wiki.openstreetmap.org/wiki/Recording_GPS_tracks">http://wiki.openstreetmap.org/wiki/Recording_GPS_tracks</a>). However, I am very new to OSM contributing and was wondering if there is a set of best practices (how much is too much data, how to snip trips for privacy, etc.) or if there is someone I could work with directly to ensure that the data I give you is both private (for us and our clients/drivers) and useful (to the community).</div>
<div style="font-family: arial, sans-serif; font-size: 13px;"><br></div><div style="font-family: arial, sans-serif; font-size: 13px;">Specifically, I'm interested in using these traces to identify where we might be missing small connector roads or other features that could improve the accuracy of routing built on OSRM. Another potential application would be to help identify areas of bad traffic or help improve speed profile information - I realize this isn't something currently supported by OSM but to the extent our data are useful for new or experimental features or data sets I'd like to know how to help out.</div>
<div style="font-family: arial, sans-serif; font-size: 13px;"><br></div><div style="font-family: arial, sans-serif; font-size: 13px;">If anyone has direct experience in this area I'm open to thoughts and suggestions. Also, if anyone knows people who I should contact it would be awesome if you could make an introduction. We have a very large volume of data that I hope can significantly improve the quality of OSM.</div>
<div style="font-family: arial, sans-serif; font-size: 13px;"><br></div><div style="font-family: arial, sans-serif; font-size: 13px;">Best,</div><div style="font-family: arial, sans-serif; font-size: 13px;"><br></div><div style="font-family: arial, sans-serif; font-size: 13px;">
