map writer .map file generation problem

[Radek]

Hi Guys,

I'm new to mapsforge development. Currently i'm trying to use mapsforge-writer plugin for Osmosis to generate .map from .osm file produced from ESRI shape file .shp.

OSM file that I'm trying to convert has been generated from .shp file by Merkaartor 0.18.1 (at the beginning I've tried to use JOSM for conversion, but I've found out that files produced by this program are not fully compatible with 0.6 spec - https://groups.google.com/forum/#!topic/mapsforge-dev/NF6V9CGjrhY/discussion, and Osmosis has problems with parsing it).

Conversion process that I tried:

1. .SHP file imported to Merkaartor 0.18.1

2. .OSM file exported from  Merkaartor 0.18.1 (from .SHP imported in 1.)

3.  Sort operation by osmosis-0.40.1 with command: osmosis --rx file="d:\bounds.osm" --sort --wx file="d:\bounds_sorted"

4.  Converted to .map file osmosis --read-xml file="d:\bounds_sorted.osm" --mw file="d:\bounds_sorted.map" bbox=51.69529,19.33785,51.84618,19.62886

Output from Osmosis is as follows:

osmosis --read-xml file="d:\bounds_sorted.osm" --mw file="d:\bounds_sorted.map" bbox=51.69529,19.33785,51.84618,19.62886

I've also tried writing .osm to .pbf format first, and with no success. 

As you can see there are no problems during generation (at least not "visible" from console output). Unfortunately generated .map file seems to be corrupted - it has very small size, and after trying to display it with mapsforge there is blank white screen. I've read that this could be caused by defining wrong bounding box parameter but I think the one I pass is OK. Furthermore I’m certain that map-writer-plugin with Osmosis on my environment (Windows 7) works as I've tried to generate .map file from .osm data extracted from openstreetmaps.org page with success.

I think that the problem is rather in my OSM file (I have no idea what) - I've included its simplified version in this post with output .map file. Can anyone please take a look at it - maybe someone will point me what I'm doing wrong? Or what is wrong with my .osm file.

Thanks in advance.

I cannot look at your file right now,but i think your problem are negative ids in the osm file, which osmosis just drops.

Thanks Ludwig for quick reply - I'll try to to parse the file to make ID's positive and report the results.

Cheers

Hi,

Unfortunately, changing ID's to positive does not resolve the problem. Still same effect - corrupted .map file.

Fixed .osm file is included to this post. Any other ideas?

Thanks in advance

I have no problems with negative ids and also use the sort option. With osmosis 0.40.1 something like that:
osmosis --rx file=country.osm --s --mw file=country.map type=hd bbox=minLat,minLon,maxLat,maxLon tag-conf-file=tag-mapping.xml

I see you don't use custom tag mapping but the default one.
Maybe the tags in your shp/osm file do not correspond to the ones in the default tag mapping file so the produced map is empty?

[Radek]

Thank you for your advice emux. 

Untill now I've somehow put no attention to tag-mapping file. I'will get a good look at it - your hint sounds reasonable. I'll report the results

Cheers

I use negative ids for data that I merge using osmosis and they work just fine.

Neil

[Radek]

Yup,that was it. 

Many thanks for your advice emux!
