Hello.
I would like to use osmosis directly as a lib into a java
application. Unfortunately, there is no documentation whatsoever on how
to do so. What I would like to do is to extract some ways from an osm
pbf file based on some set of tags (like all "highways" of the tpe
"motorway" or "trunk" for example), process these ways with my custom
piece of java code (to add or remove some properties, split them in some
cses...) and then store these modified ways and their associated nodes
into a Postgresql database. But my problem is that I couldn't find:
- how to read a pbf file (given a java.io.File object)
- how is osmosis handeling nodes cache (when the "--used-nodes" option
is used in command line mode, do osmosis actually store a cache of nodes
already parsed somewhere or do it need to read the osm file once again
to filter them based on the ways (or relations) filtered out?)
If someone knows the osmosis source code well enough to help me with
this, it would be really nice ;)
Thanks
Thomas
