[mkgmap-dev] Question reg. points with extended type

Sat Apr 6 17:28:29 BST 2013

Hi Thorsten,

good that you asked. I just found out that the overview2 branch did no
longer create the 
index in the same way. This is corrected with r2558.

The so called global index is created when you use the --index option. I
don't know for sure 
what the device does with it. 
I assume that a map with many point with extended types needs longer to list
the POIs,
because they are not indexed. Don't know if that can be changed.
