Location errors

iSpot has started truncating/rounding (I haven't investigate which) (some? all?) location co-ordinates to the nearest degree. It did that to my last observation, and I tried looking up the location on someone else's recent observation - he had a couple of photographs that seemed to represent a wildflower seed mix, and I wanted to see if it was a council amenity planting - and found the same, with in this case the location being in the middle of the sea.

Known bug

So this still isn't fixed?

It could be a new bug with the same symptons ....

Unlikely...

but only because I can still reproduce the rounding problem I reported, so that bug hasn't been fixed. It crops up when one zooms in using the 'Satellite' view of the map to select a location, and even then, only for some locations. The problem could be widespread; I suspect few users revisit their map locations. This acknowledged bug doesn't seem to be a priority. I hope recording bodies somehow filter whatever data they receive from iSpot, starting with land vs. sea.

My observation was only moved ...

... 20 or 30 miles - from one county to the next - so land vs sea filtering wouldn't work in that case.

The necessary filtering would be to remove observations with integral latitude and longitude co-ordinates (however they are represented in the database).

The may be a question as to whether the bug is in iSpot or in Google Maps.
