Hi Mike,

thanks, you are right, I've changed removeSimpleDuplicates() in r4525.

Betreff: Re: [mkgmap-dev] Nearby POIs

Hi Gerd, The solution gets rid of the unexpected error message, however, it
does not delete POIs that were originally coincident. Perhaps a better
solution would be not use the set of locations for testing uniqueness in
removeSimpleDuplicates, instead using a list and trawl the list using high
precision comparison to determine whether the coordinate matches another. It
could even compare both in high precision and displayed precision so that
POIs which have been moved to be coincident are also removed. As the list
will only contain a few coordinates it shouldn't be expensive. To help
minimise enumerations, the list could be ordered by longitude or latitude if
necessary. Another option would be to derive a class with different iterator
comparator which might be useful elsewhere.

Regards,
Mike

but it is also is a constant source for problems like these
