Hi Gerd, Can you use the overview mapname/number parameter if this is given in the mkgmap call? --overview-mapname=name If --tdbfile is enabled, this gives the name of the overview .img and .tdb files. The default map name is osmmap. --overview-mapnumber=8 digit number If --tdbfile is enabled, this gives the internal 8 digit number used in the overview map and tdb file. The default number is 63240000. And the filename_mdr.img is always the same as the filename.tdb and also the same as overview-mapname or overview-mapnumber?
I want to identify the overview map itself, not the ovm_*.img work files . Reg. <id>.ovm: The work files are correct img files, so I think that we should use the *.img extension to allow double clicks for opening. (<id>.ovm would require new associations)
