(a) was it in the right place and
(b) resolution are you giving the location to nearest 10m, 100m, 1km, 10km or worse than 10km.
You may want to discuss this on the forum and/or send thoughts on this to the iSpot inbox (address shown on the bottom of most iSpot pages).
Having the right location and resolution of 10km or better is vital for most biological recording.
If you don’t know what accuracy you are giving your observations at that would also be useful to know.
It can be tricky to work out the resolution of your observations if you are using the map to mark where you made the observation. Ideally you would be as zoomed in as possible so you can see the particular tree or detail of part of the park you are making the observation in, this may be 10m resolution. If you don’t zoom in this far it can be more tricky to estimate resolution.
Those people using gps or taking photo on phone with the gps on the phone putting in the location automatically may also achieve 10m but be careful as sometimes the location can be wrong. For example if the gps looses the satellites for a short time it may put the location as far away from the true point.
