[mkgmap-dev] POI indexing, problem with label 0x2800

Sun Apr 30 10:13:28 BST 2017

Hi Andrzej,

you wrote that you noticed an increase in the LBL file. I think you use option --make-poi-index, but
the help says
--make-poi-index
        Generate the POI index (not yet useful).
I've never used this option because of this description, so maybe I should add this to my test cases....

The svn log for this option (r1170) says :
"Add --make-poi-index option to enable POI index generation.

The POI index, which used to be generated by default, doesn't actually
appear to be useful at this time. So now it's only generated if you
give this option."

Unfortunately it doesn't say what the expected effect of the index is. The code for this was added with r984 :
"Add support for exits (motorway junctions & services).

One major annoyance is that when finding exits, the GPS prefers to
find the exits on the basemap rather than the OSM map. Don't know
at this time how to fix that.

Also included in this commit is support for building the POI Index.
I originally thought this was needed for the exits but I don't think
it is now but it may still be useful so I am leaving it in."

I'll try to find out more. Maybe you can try without the option --make-poi-index
and see if that changes anything besides img file size?

Hi Gerd,

 > I've added option poi-excl-index in r3922 in the branch.

Thanks Gerd, this is useful for me.

Have you looked at code for creating LBL? I think there is a structure
there for POI index, maybe it should cooperate with data in mdr?
