[mkgmap-dev] change mdr25 logic

Tue Nov 16 10:00:32 GMT 2021

Hi Ticker,

I think mdr25 is recalculated. I modified mkgmap to write only one city name for mdr25 and created a gmapsupp with MapSource. The mdr25 in the file contains more entries, so it should be possible to use that for testing.

Hi Ticker,

I didn't notice that the Mdr25 is the same. In that case it is really no help.

Hi Gerd

If the --gmapi map I load isn't build with --index, MapSource map
install doesn't create one in the gmapsupp.img. I couldn't see a way of
forcing either MapSource or BaseCamp to build an index.

If I start with a --gmapi with --index, using BaseCamp/MapInstall, the
Mdr section seems to lose Mdr13, Mdr14, Mdr15, Mdr21, Mdr23, Mdr26,
Mdr27, Mdr28 and gain Mdr17. The other Mdr sections have the same
number of records, but, as expected, different record sizes. Mdr25
hasn't changed.

I also get:
00007420.MD2    141492

along with the normal:
00007420.MDR    1166713
