[mkgmap-dev] MDR and city streets on different tile from POI place=city

Wed Nov 3 14:27:47 GMT 2021

Hi Ticker,

yes, might be better to change that to be more precise. Question is if Aa and AA are two different cities or just different spellings of the same city. The latter is much more likely, so it seems justified to use only one.
We have more code which tries to ignore case, e.g. for --housenumbers I often use String.equalsIgnoreCase() to work around different spelling in road names and addr:street or place names and addr:place.

Hi Gerd

The scenario is:
 --lower-case,
 2 tiles,
 mkmap:city "Aa" area that spans the tiles",
 streets with this mkgmap:city in either/both tiles,
 the City POI "Aa" on one of the tiles,
 another city, eg "AA" in the tile without the "Aa" POI,
 streets for this.

I am finding streets in the tile with both regions are all assigned to
one or the other and this behaviour is effected by the presence of the
City POI.

PlacesFile::CreateCity(not unique) will return the same City record for
both "Aa" and "AA" so I propose to remove the toUpperCase() from it
when --lower-case (unless ascii/cp0 which forces upper case)
