[mkgmap-dev] max-nodes value ...is far above highest node count...

Sat Nov 9 10:42:59 GMT 2019

Hi Arndt,

if you search for a line containing
"Creating the initial areas took"
and the reported value is much higher than a few seconds you may try to decrement the resolution by 1.

BTW: Do you use the default 13 or a higher value? If higher, why?

Gerd

Hi Gerd,

thank you for helping me again!
Sorry, i meant of course "splitter".
So far the message comes only by splitting "Iberia" (Spain, Andorra, Portugal).
splitter needs 16 minutes, mkgmap 2 hours. The map has ~2,4 GB.
For comparison, Germany split needs 23 minutes, mkgmap 1 hour. The map has ~3,7 GB. (without the message)

Hi Arndt,

you get this message from splitter, not mkgmap. This is only about performance of the phase in which splitter calculates the tiles. This depends on the chosen resolution. The higher the resolution the longer it takes. If you split very small input files simply ignore this message, but if you split e.g. a well mapped area like Germany you simply waste time and energy when you chose a bad combination of max-nodes and resolution.

Good morning,

sometimes mkgmap say something like this:
max-nodes value 1600000 is far above highest node count 249343 in single grid element, consider using a lower resolution.
What does that mean? The map seems to be OK.

Best regards
Arndt
