Hi Andrzej, splitter can do that for you with some limitations. keep-complete will only handle first given file to splitter. This is quite useful if you give splitter a normal osm-file and a srtm-data-file. So it's merged within splitter and you get all data in your tiles.

Hi,
I would be interested in creating single img tile form multiple input files. Since description of "input-file" parameter is quite imprecise, I have done some testing.
I have used template.args in a following form:
mapname: 08900000 input-file: 08900001.osm.pbf input-file: 08900002.osm.pbf
mapname: 08900001 input-file: 08900003.osm.pbf input-file: 08900004.mp
What I have observed: If pbf files cover different area, then mkgmap creates separate img for each pbf. Second mapname seems to be ignored. Mkgmap outputs files with sequential numbers.
Polish format mp is read, since mkgmap issues warnings, but these data aren't included in any img.
And most interesting: if pbf files cover exactly the same area, they are merged into single tile. This is what I'd like to get.
Unfortunately merging is not recognized when creating tdb, index and preview map. For this files, each pbf is treated as separate tile. Resulting mapset is not accepted by Mapsource, it refuses to start.
I guess, that merging pbf into single tile is not supported and it is only some incidence, that it works for pbf with the same area. I would like to suggest, to make this procedure official and correct algorithms for Mapsource files accordingly.
Could you for example consider new option, like "add-file", which would cause merging input file with a previous one? There shouldn't be much work for pbf, since it nearly works. And it would be a great help if it worked for polish format mp, since it would allow to add data, which is not available in OSM format.
