Hi Ticker, attached are two slightly different patches for Mdr25 which I think make the code more plausible. v2 would be my choice. I've not yet tried to find out (again) how the sort works regarding strength. In my maps I see that Mdr25 contains fewer records than Mdr5 (e.g. 7609 of 8275 or 1146 of 1850), but I have no clue yet how to find out which recrods from Mdr5 are skipped, means, what exactly has to be compared.

Hi Ticker, just learned (again) that MapInstall fills Mdr25 when it writes a gmapsupp. That should help.

Hi Ticker, both MapSource and Basecamp allow to install a map on the device or on a USB stick that has a Garmin directory. You select one or more tiles and the programs write a gmapsupp.img with an index for those tiles.

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 Ticker On Mon, 2021-11-15 at 18:55 +0000, Gerd Petermann wrote:

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 Gerd I suspected this after I noticed that the repeat flags in the various street Mdr sections had been changed when there were differently cased versions of street names. MdrCheck complains about the result. My test example didn't have differently cased versions of cities so Mdr5/Mdr25 didn't change. Ticker On Tue, 2021-11-16 at 10:00 +0000, Gerd Petermann wrote:

Hi Gerd Mdr25 is effectively sorting by country, city, region. However it only detects changes in city or region. This would only be a problem if there were adjacent equal city®ion but in different countries - this is very unlikely. An additional test for this would clarify; maybe starting off as a warning or assertion. My reading of the code is that Mdr25 will be smaller than Mdr5 when the same city/region/country occurs in more than one map. The change c.getMdrCountry().getName() to c.getCountryName() is clearer and should give identical results. There are number of places in mdr where collator.compare() should be considered instead of .name.equals(). I think this should be done as a separate batch once r4809 has settled down.
