[mkgmap-dev] Creating a point with a full address that can be found

Fri Jun 9 10:08:26 BST 2017

Hi Ticker,

do you use the option --make-poi-index? If yes, it should have an effect
when you change the limits. What I wanted to say is that I did not see any effect of that
index during my tests with the Oregon. I did not yet dig into this part of the code,
but I think it is somehow related to the MapSplitter limits.

I'll be busy with other things during the summer, so I have no time to
analyse it in detail.

Gerd

Hi Gerd

Yes, this code seems to be redundant; changing the limits didn't effect
the behavior on my eTrex, so I guess they were chosen to attempt to
match the in-build behaviour of the device.
