[OSM-dev] Longitude/Latitude result different from Google/Bing
Hi, If you look at this page, you will see a cell tower at: 39.184556 / -77.249806 http://www.cellreception.com/towers/details.php?id=1230956 In google map , it shows the same thing when we type 39.184556 -77.249806. But, in OpenStreetMap, you see the location of the cell tower is a little bit different: http://www.openstreetmap.org/search?query=39.184556%20-77.249806#map=18/39.18483/-77.24953 Do you have an explanation for this? Should I expect OSM to always have a longitude/latitude a little bit different that what it really is? Thank ___ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev

Vince It is not quite clear what you are getting at. Currently the tower node is located at 39.1847132, -77.2495875 http://www.openstreetmap.org/?lat=39.1847132lon=-77.2495875zoom=18 in OSM and likely the position was derived from bing imagery. The difference to the position you give is 26 meters (result from an online calculator that I didn't check myself) which may indicate that the imagery there is slightly misaligned or that the position of the cell tower is not actually in the middle of the water tower which has a diameter of roughly 30m, but on one side of it.

Actually as you see here http://mc.bbbike.org/mc/?lon=-77.24981lat=39.18456zoom=18num=2mt0=google-satellitemt1=bing-satellite it is very clear that the cell tower is a separate structure that is south west from the water tower that is mapped in OSM at a good 20m distance.

Yes, the cell tower is located indeed at approx. 20m from the water tower. I thought that OSM was showing the CellTower, but it is the water tower, so it is fine. Thanks.
