Summary: Geocode reverse lookup needs improvement
Description: The geo lookup ws used by coord interp is showing some flaws. Part of the problem is not honouring source projections of coords, and part of it is the ws base layers not matching up perfectly. PF-1354 shows one example where it looks like the land layer and eez leave a gap. This can be improved by fuzzying the lookup (maybe reduce precision) or improving the base layers, or both.

Here is a good example of a "border case". A record with ISO, country and coordinates is incorrectly receiving a flag of "country coordinate mismatch"

geocode-ws returns Spain : http://api.gbif.org/v1/geocode/reverse?lat=41.038795231273376&lng=-6.921280251735951
Ideally, it should probably return Spain and Portugal.
But, if we query the latest version from http://www.marineregions.org/eezsearch.php, we get Portugal so this case might be solved by updating the EEZ database.

The updated database is still returning Spain: http://api.gbif-dev.org/v1/geocode/reverse?lat=41.038795231273376&lng=-6.921280251735951
So I need to look into this further, maybe check the shape file resolution we are using is appropriate for our coordinate accuracy.
Google also says it's in Portugal, about 200m from the Spanish border.

Comment: Fixed, allowing more tolerance (5km, 25km) from geocoder.
