Index with little ram?
Hello together, mkgmap needs a lot of RAM to build the index for the adress search. Also for the gmapsupp. My computer has 4 GB and it´s not possible to build the index for a germany map. It works, when i not use the "x-split-name-index" Option. But I want to use this. The map has 2,21GB (only the mapfiles) The Computer from my son has 12 GB. This machine has no problem with germany, but failed, when it builds the index for an europe map (12,1GB). Is it possible to change the index-build process so, that also a little computer is able to build the index? By the wy, the x-split-name-index works fine by street names. Is it possible, that it also works by town-names? Best regards Arndt
yet it works for me just takes some fidleing around with some variables doeing dach map now Stephen On Sun, Jan 24, 2016 at 7:25 AM, Arndt <arndt@speichenkarte.de> wrote:

Hallo Arndt, ich nutze einen PC mit 6 GB RAM, und weise in der Commandline zum start von mkgmap java 5500MB zu .Damit mit kann ich den europai_mdr.img erstellen. Habe aber die x-splitt-name-index nicht benutzt. Auch die gmapsupp-option nutze ich nicht. mfg thomas Von: Arndt Datum: Samstag, 23.

Reg. memory: If you have a 64 bit system it is probably better to buy more memory. I think Steven did already try to reduce the memory usage so I guess there is not much room for improvements. reg. city index: I assume it is possible, not sure if it makes sense. I guess you have names like "Samtgemeinde Harpstedt" instead of "Harpstedt" ? In that case I think it would be better to use subst like we do for "Gemeinde". Do you have positive examples ?

6GB for Europa? I use the extract "Europa" from the geofabrik. With my style a 12GB Machine failed. I make a Test with the "Balearen". With my style the mdr-file has 6,5MB. With the default style only 5 MB. In my style some ways exists more than one time. For example a street with surface=cobblestone. There are 3 lines, one invisibel for routing, one for the look and one for a marker, that the surface is bad. Is it right, that only lines with highway=* use for adresses? Perhaps its possibel to use only one highway Tag for the ways and for the other infos i use a custom word. Why it is necessary that the mdr build in only one step? Perhaps it ist possibel, that this run a few rounds. x-split towns: Bad Honnef El Paso El Arenal Wildbad Kreuth Arndt ___________________________ Steve Sgalowski: yet it works for me just takes some fidleing around with some variables doeing dach map now Thomas Morgenstern: Hallo Arndt, ich nutze einen PC mit 6 GB RAM, und weise in der Commandline zum start von mkgmap java 5500MB zu .Damit mit kann ich den europai_mdr.img erstellen.

ich have on my 64 bit Windowsmachine and 5500 MB for java no problem. I also use the geofabrik europa-extraxt; aktually ~ 16 GB osm.pbf. 1. step : Splitter creates ~ 570 <name>.osm.pbf files and as 2.step mkgmap makes the img-files. But in this 2. step i create not a <name>_mdr.img ! As 3. step i run mkgmap with this options : --index --tdbfile --area-name=Europa *.img. I never create a gmapsupp; only PC -Installation. This method has additionally advantages: you can create many country-spezific-maps with option --index --tdbfile --area-name=Poland poland*.img thomas Von: Arndt Datum: Sonntag, 24.
