OpenStreetMap

walking on water without getting wet

Posted by wilpin on 26 September 2009 in English (English)

Having mapped many of the streets of Teignmouth today I hadn't realised I'd performed a miracle - see map.

There are possibly three explanations:

1) my gps was giving me false readings

I checked it against Garmins GB map and the track more or less was spot on.

2) the tide was out

Could be, but it has been out ever since I moved to Devon (35 yrs)

3) the osm coastal data is not 100% accurate or up to date.

I wonder...

Location: Teignmouth CP, Teignbridge District, Devon, South West England, England, United Kingdom

Hi,

seems to be a problem with the coastal data. Look at this tool:

4) OSM coastal data cares about the high water mark...
