China
Oh, well... this is a quite a big country, maybe you can specify the parts of China you want to cross.. :shock: :shock:
Are you using custom polygons ? Can you recommend a tool ? For my first try (tajikistan) I used a polygon I found online, I think it is the official from openstreetmaps, it is heavy with 3458 lines.
Yes I use custom polygons, I draw them as tracks in QV6 (former Touratech QuoVadis), export them as GPX and run a Perl-Script that
- converts the GPX to Poly
- writes the batchfile for the final batch that calls the mapwriter with the right BBox.
(Its part of a series of nested scripts driven by a central make-file)

Tatschikistan is running now for 9hours and says "completing read" :lol: so ist will run for a day or more further...
If you feed the data into the mapwriter its a good idea to use a custom tag-mapping.xml for these wide and "empty" countrys that forces even low-level roads and ways to appear at low zoom-levels otherwise you dont have any overview an keep scroling around on a empty map - I hope you got the picture...
Something like this (towns)
<pois>
<osm-tag key="place" value="city" zoom-appear="6" />
<osm-tag key="place" value="country" zoom-appear="3" />
<osm-tag key="place" value="hamlet" zoom-appear="9" />
<osm-tag key="place" value="island" zoom-appear="9" />
<osm-tag key="place" value="suburb" zoom-appear="9" />
<osm-tag key="place" value="town" zoom-appear="8" />
<osm-tag key="place" value="village" zoom-appear="8" />
</pois>
and roads
<!-- HIGHWAY TAGS -->
<ways>
<osm-tag key="highway" value="bridleway" zoom-appear="9" />

Dont use this code in crowdy european aeras, it might couse performance problems there.
I will give you a download link as soon a Tatschikistan is ready - so you can get an idea what OSM worth in these aeras.
