<div>I'm afraid I have to agree with Frode Roxrud Gill in his doubts.</div><div><br></div><div>When I started to add a few things to OSM about a year ago, I was very happy to see that stallis had added so much. In fact, he had added so much detail that I wrote him in OpenStreetMap and asked if he really had collected all this data in a legal way. He answered that he had been driving a lot and had also been a taxi driver, and had a lot of traces. I was in doubt, but decided to accept his explanation. Now that Frode has had the same thoughts as me, I am glad he raised the question here.</div>
<div><br></div><div>I had a look around my local area and found some odd things:<br></div><div><ul><li>Way 38810231 goes from Odderhei Terrasse and is a combined driveway for one house and a bicycle road to a bus stop in Dvergsnesveien. When the bicycle road gets down to Dvergsnesveien it is blocked by a guardrail. A small car could possibly pass through on the right side and over the sidewalk, but it is obvious that you are not meant to drive here.</li>
</ul></div><div><ul><li>Way 38810230 does not exist at all. According to my GPS, there's a 2 meter cliff here at the side of Dvergsnesveien.<br><br></li><li>I inserted the way 38785737 where Stallis had entered the two roads Korsvikhaven and Korsvikgrenda as a normal T crossing, but there is (for at least ten years) a short bicycle road between the two roads that is blocked for cars. I believe (but I am not sure) that Google maps had a T crossing here a year ago also, but Google have fixed it now.</li>
</ul><div><ul><li>The set of service ways starting with way 38908617 and going north and east of there is a skidpan training area that is not public, but only available for scheduled sessions. Google Maps also shows roads here. He can of course have had a session there, so it might be OK. To his defense, he has also added way 61350739 which is not shown in Google maps. I don't know the place well enough to say what this way is.</li>
</ul></div></div><div>So just as Frode says, it would be best for all parts if stallis has acquired his data in a proper way, but an investigation seems to be appropriate.<br></div><div><br></div><div>Best regards,</div><div>

The user "demivee", formerly known as "stallis", has mapped almost the</div><div>
entire Kristiansand area and its surroundings. I would be very happy</div><div>
for, and impressed by, this user if it turns out all edits are based</div><div>
on free data, but I have a feeling this is not the case.</div><div>
<br></div><div>
At two places in Songdalen, a county immediately west of Kristiansand,</div><div>
common available maps ( <a href="http://openstreetmap.org/" target="_blank">http://openstreetmap.org/</a> ,</div><div>
<a href="http://kart.gulesider.no/" target="_blank">http://kart.gulesider.no/</a> , <a href="http://maps.google.com/" target="_blank">http://maps.google.com/</a> and</div><div>
<a href="http://www.finn.no/kart" target="_blank">http://www.finn.no/kart</a> ) have differed from reality and eachother,</div><div>
and in both cases <a href="http://openstreetmap.org" target="_blank">openstreetmap.org</a>, with data provided by</div><div>
stallis/demivee, has matched Google Maps and not reality. The places</div><div>
mentioned are Koleknibvegen <URL:</div><div>

<URL: <a href="http://www.openstreetmap.org/browse/changeset/6262577" target="_blank">http://www.openstreetmap.org/browse/changeset/6262577</a> >, based</div><div>

I have no hard evidence, but these two locations, together with the</div><div>
fact that the user has no public GPS Traces (even after kindly asked</div><div>
to provide them), created lots of small roads (we usually don't map</div><div>
single-house driveways), a sudden usernamechange after his username</div><div>
was revealed in a thread on the Norwegian Openstreetmap mailinglist</div><div>
(started by me, in Norwegian. <URL:</div><div>
<a href="http://lists.nuug.no/pipermail/kart/2010-October/002049.html" target="_blank">http://lists.nuug.no/pipermail/kart/2010-October/002049.html</a> >, makes</div><div>
me believe his edits are based on data from Google Maps or their</div><div>
upstream provider.</div><div>
<br></div><div>
To remove any doubt that the data in openstreetmap are free, I would</div><div>
ask you investigate the user "demivee"/"stallis" and what he has</div><div>
mapped in the Kristiansand area. For the state of the map in the</div><div>
Kristiansand area, I would be very glad if my gut feeling is wrong..</div><div>
