Hi Stephen,

please explain I don't see how the suggested change in splitter is related to 
this.

Betreff: Re: [mkgmap-dev] Size checks in splitter

when splitting Australia in the osm file of 7 gb in size , that would be 
usefull, as i set the max nodes to 90,000 to make smaller tiles as i get  
frequently , that there is not enough room in a single gmapsupp.img file to 
hold all the data .

Hi all,


years ago we added a check in splitter r251 to make sure that it doesn't write 
extremely large tiles.

See

http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2012q1/013611.html

and

http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2012q4/015707.html


In short: The problem is that the precomp-sea option will add a huge amout of 
sea polygons to such a tile,

another problem is that the bounds option loads a huge amount of data.


I've now noticed that this check might not be useful if you use splitter to 
split a large file into a few smaller tiles,

esp. the whole planet with num-tiles=2.

I'd like to skip this check when

a) --num-tiles is used

b) --max-nodes value is large, e.g. higher than 10.000.000


Another option would be to add a new option like --skip-size-check.


What do you think?

Gerd
