[mkgmap-dev] RAM and mdr Europa ?

Hi Mike,

my  understanding is that mkgmap can decide which elements are used to build the index
and what string are put into the index.
AFAIK it can not decide what you can search in the device, as it may also perform a search without an

Is it possible to not put POIs into the index, but still have them
displayed? I would like to have gates and stiles on my map, but not have
them searchable in the index. Is this possible?

Hi Thomas,

I think it depends on the style. The more indexable objects you create and
the longer the names, the more memory is needed.
Andrzej suggested not to put POI with type 0x28 into the index. Do you think
this would help to reduce size in your case?
