Empty Areas in US West (Area too small to split)?
Hi, when I take the geofabrik US West extract, run it through splitter and then try to run mkgmap on it, I get errors on a couple of areas [1]. I tried reducing the max-nodes parameter for the splitter from 1000000 to 750000, that didn't help. The problem in this case seems to be not too many nodes, but rather *too few*. When I try loading those mentioned areas into JOSM, I get an error message: "No data found for this area." Mkgmap doesn't seem to handle this well. The map generation process stalls without any further error message. Could this be fixed? I can provide the original us-west.osm.pbf on request.

Dominik, I think this is a known problem of mkgmap. The problem is that the algorithm that divides the map into subdivisions has to consider several restrictions. The current algorithm is not very optimal to solve these restrictions. I started working on this but didn't finish up to now (http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2011q1/009960.html). WanMil

Hi WanMil, thanks for the pointers. Question is then: 1) How can I create an incentive for you to continue? ;-) (Any estimates?) 2) Do you know any workaround? Dominik On 05.05.2011, at 20:33, WanMil wrote:

Dominik,
Hi WanMil,
thanks for the pointers. Question is then: 1) How can I create an incentive for you to continue? ;-) (Any estimates?)
find another Java programmer ;-) At the moment I am very busy with the locator branch so the chances are low that I will have time to continue with that. If anyone has some spare time and wants to have a look on it I will provide my findings and some tips how that possibly can be fixed.
2) Do you know any workaround?
I am not sure. Maybe it helps if you split the tile exactly at or very close to the given coordinate. WanMil
