Does OSM-Composer have an English version that works with the .6 API yet?

I don't know - however, I still believe it would be a useful option for mkgmap since OSM-composer is quite heavyweight. I would like to be able to use mkgmap on its own... -- Till PS: Please cc me on any replies - I'm not subscribed to the list, thanks.

Hi Till,

you can use the OSM-Composer to create your map. This tool is generating such a report.

Hi.

I'm a new user of mkgmap -- many thanks for the great tool!! -- and I have a suggestion:

After creating one of my first maps I was surprised to not see a particular feature in the 'img' map even though it is present in OSM.

After digging around for a while I found that this feature is marked in OSM as 'railway=disused'.

I found that the default mkgmap style has a 'railway=abandoned' rule and after I added 'railway=disused' everything worked as expected. Apparently, since mkgmap didn't find a rule for 'railway=disused' the railway just got silently dropped.

What I believe could be useful (if this feature is already available then forgive me posting) would be an option to report ignored tags and tag/value pairs which would alert the user that certain features are not rendered by the current style.

Thanks again -- Till

MapComposer use his own splitter. The tag-statistic is done while splitting and manipulating the tags. MapComposer-statistic includes every tag. All in all I think it more easy to use a service like taginfo.openstreetmap.de. aighes -- View this message in context: http://gis.638310.n2.nabble.com/mkgmap-style-parsing-question-tp5637919p5641...

I don't think this is doable. There are thousands of tags and tag/value pairs out there which are documented nowhere. Just have a look at Tagwatch (http://tagwatch.stoecker.eu/Planet/De/index.html). Mappers do have a lot of imagination sometimes ;-).

I see it the other way. I *think* it should be doable not to hard. The style matcher has to match the style rules for each element in the osm file. If he could not match any rule then it should printout a warning.

I expect them to be thousands too. I don't know if this would help to user.

This is the statistics from OSM-Composer, maybe it's helpfull for this discussion. There is a limit you can set, below this limit the TAGs are not mentioned. Aditionally you can set a flag to add up only the tag-name without each different value, such tags are shown with a * only (e.g. is_in/*) not mapped Tags: 3465 way:layer/* 3352 way:is_in/* 608 way:addr:interpolation/* 562 way:electrified/* 422 way:usage/main 395 way:tracks/2 370 node:highway/turning_circle 327 way:tracks/1 274 node:dispensing/yes This feature is one of the reasons I am using the Composer, but without the add_up option, there will be thousands of entries in this list. Composer also has an ignore option, these TAGs are completely ignored. Walter

Johann,

the idea to printout a warning sounds good. But there are some restrictions within mkgmap that makes it unfeasable.

Yes, unfortunatelly I know the internas somewhat :-)

When mkgmap reads the OSM data all tags which keys are not referenced in the style files are dropped. This improves the performance and reduces the memory footprint *enormously*. The style file processing is done at a later stage.

So why not printout a warning at this stage, where the key is dropped? Or maybe not printout directly, but fill a statistics class with it. So the user can see, there are x (thousand) occurences of a key he has not handled in his style file.

So in case your style file only contains a rule for natural=water you would get a warning for natural=land but not for landuse=residential.

I don't think that's what you want?

I personally don't need this feature at all. It was meant only as a suggestion in response to the original poster. I will not implement it. ;-) If I will find some time for the mkgmap project, I have other preferences. Johann
