Hello. This is my first post!
I’m fairly new to the openstreetmap world. I have been playing around with the PostGIS version of the database using osmosis to convert the osm files to pgsql-dumps and then importing those. The OSM database is importing fine. I’m having a problem in filtering the data. I thought I put together a filter list that would remove non highway nodes (removing random POIs), but have found the resulting database missing normal way nodes also.
One sticky point is I also editted osmosis (0.31.2) to enable some easier way filtering. I updated WayKeyValueFilter.java to support wildcards so I could include all values on a certain key. It supports the highway.* syntax. I ended up putting all the key.value pairs and then at the end used the new syntax for oneway.,junction.,maxspeed.*
WayKeyValueFilter.java
/**
* {@inheritDoc}
*/
public void process(WayContainer container) {
Way way = container.getEntity();
boolean matchesFilter = false;
for (Tag tag : way.getTags()) {
String keyValue = tag.getKey() + "." + tag.getValue();
** if (allowedKeyValues.contains(tag.getKey()+“.”+“*”)) {
matchesFilter = true;
break;
}**
if (allowedKeyValues.contains(keyValue)) {
matchesFilter = true;
break;
}
}
if (matchesFilter) {
sink.process(container);
}
}
The command I’m running (I’ve made it on multiple lines so it’s easier to read)
time bzcat michigan.osm.bz2 | ~/osm/osmosis-0.31.2/bin/osmosis -v
–read-xml enableDateParsing=no file=/dev/stdin outPipe.0=rawosm
–way-key-value inPipe.0=rawosm outPipe=wayfilter keyValueList=“highway.road,highway.unclassified,highway.residential,highway.tertiary_link,
highway.tertiary,highway.secondary_link,highway.secondary,highway.primary_link,highway.primary,
highway.trunk_link,highway.trunk,highway.motorway_link,highway.motorway,highway.traffic_signals,highway.turning_circle,
highway.motorway_junction,oneway.,junction.,maxspeed.*”
–remove-tags-0.6 inPipe.0=wayfilter outPipe.0=filtered keys=“leisure,created_by,class,source,note,access,railway,bridge,layer,amenity,route,surface,level,shop,tunnel,
cycleway,natural,motorcar,boat,motorcycle,gnis,foot,abutters,waterway,bicycle,man_made,place,lanes,
aeroway,postal_code,is_in,statscan,attribution,ele,type,stream,building,landuse” keyPrefixes=“tiger,geobase,nhd,nist”
–used-node idTrackerType=BitSet inPipe.0=filtered outPipe.0=usednodes
–write-pgsql-dump inPipe.0=usednodes directory=/home/alang/osm/dumps/mi enableBboxBuilder=yes enableLinestringBuilder=yes nodeLocationStoreType=“TempFile”
So like I was saying, I wanted just nodes attached to highway tagged ways and I wanted to remove tags on nodes that were not useful to me.
the --way-key-value list should include highway., oneway.,junction.,maxspeed.
–remove-tags-0.6 should remove some tags that I just don’t need
–used-node should only include nodes that are used in ways
It’s possible I only needed --remove-tags-0.6 and --used-node
I live in michigan. One particular intersection which filtered incorrectly was at lat:42.335961 lon:-83.508024 (Beck/Warren). There ended up being no nodes here.
I’m going to try the --remote-tags-0.6 and --used-node now, but I was wondering if someone could help explain the issues with how I did it above?
