[mkgmap-dev] [PATCH v1] Multipolygon: Allow nested inner polygons

Fri Mar 5 21:05:16 GMT 2010

> There have been different opinions about this patch.

> There is one controversal point:
> Should mkgmap allow nested inner polygons?
>
>   From my point of view: YES. Because it does not harm in any way. The
> nested inner polygons I analysed were all reasonable. Ok, they are not
> 100% compliant to the specification but this is common to lots of others
> things in (anarchic) OSM.
>
> At the moment I see two possible changes:
> 1. Issue a warning for any nested inner polygon but process it anyhow.
> 2. Reject nested inner polygons (and issue a warning). What a pity but
> they are not 100% compliant.
>
> Please let me know what's the opinion of mkgmap community and committers
> because I want the improvements of error messages to be committed.

If it is not difficult to implement (also for others) then I would 
propose integration.
If however we knew that mapnik could not implement it without major 
rewrites, then I would not push it forward as long as it is not at least 
accepted tagging for a larger minority.
