[osmosis-dev] new areas to points converter plugin
Hello list, Inspired by the mkgmap option add-pois-to-areas I have written a new small plugin for osmosis called AreaPoints. You can find it in svn[1] now. It will add points in the output for every closed way it finds. The additional point will have the same tags as the way had. It's position is the center of the bounding box of the way (maybe somebody has a better idea). You will find some more details in the README or in the source itself ;) I have not tested its performance on big datafiles. I hope that someone else finds it usefull, too.

In your case the only option is to split it into two steps using temporary XML files as you already appear to be doing. It would be nice if Osmosis could detect this situation and throw an error, but it would take a lot of effort and add a lot of complexity that I don't really wish to attempt. Ok, thanks for your reply. I think now I understand the situation better. While reading your answer I got an idea to solve the problem without writing to disk. I use a very big buffer now: osmosis-0.35.1/bin/osmosis --rx input.osm --t outPipe.1=points \ --wk keyList=addr:interpolation,addr:housenumber --un --s --b 1 \ --nk inPipe.0=points keyList=addr:housenumber --s --b 1 \ --m --wx addr.osm This works very well if you have enough RAM and set the bufferCapacity high enough. Another possibility would be a better tagfilter that allows me to filter POIs and ways at once. The task would be for example: Give me all ways that match this way-filter and all nodes that match this node-filter or are part of the way that matches the way-filter I don't know if this is difficult to implement but I think this would be usefull.

[osmosis-dev] question about --merge
Hello list, I am new to this dev-list. My name is Christoph Wagner and I maintain the Garmin All in one Map: http://wiki.openstreetmap.org/wiki/All_in_one_Garmin_Map I want to reduce some server load (I omit details here) and tried to filter OSM-Data with osmosis. For example I have the problem to filter out all kind of adresses in an osm-file. My first guess was that: osmosis-0.35.1/bin/osmosis --rx input.osm --t outPipe.1=points \ --wk keyList=addr:interpolation,addr:housenumber --un --s \ --nk inPipe.0=points keyList=addr:housenumber --s \ --m --wx addr.osm The Problem is, that osmosis never finishes. I wonder why. No error, no writing, no CPU-usage - it just waits and does nothing. There must be something wrong with the --m I guess, but I don't know what. This one here does what I want, but needs to write out and read in again xml files for that: osmosis-0.35.1/bin/osmosis --rx input.osm --t outPipe.1=points \ --wk keyList=addr:interpolation,addr:housenumber --un --s --wx addr_lines.osm \ --nk inPipe.0=points keyList=addr:housenumber --s --wx addr_points.osm osmosis-0.35.1/bin/osmosis --rx addr_lines.osm --rx addr_points.osm --m --wx addr.osm Is this behaviour wanted? Can somebody give me a hint to do it better? I have no idea what is wrong.
