[osmosis-dev] Ignore all nodes except for point features?

[David Carmean]

Hi,

Just getting started with postGIS and using osmosis to import OSM data.  After 
figuring out that -Xmx6000m worked where -Xmx4096m did not (no idea why???) 
I'm now able to create both bbox and linestring in memory and it's incredibly 
fast :)  51 seconds for the 1.5x1.5-degree area centered on the SF Bay Area, 
which is 500 MB of osm xml (uncompressed).

At any rate, for my application, having the ways with linestring geometry is 
enough; no reason to load 1.8 million nodes. But I would like to keep any 
valid isolated nodes, such as mountain peaks, etc. So after using the nodes 
to create the bbox and linestring geometries, how might I approach selecting 
only "valid, isolated" nodes into the dataset I ultimately copy into 
postGIS?

(This is primarily to be able to use OSM data in a GIS app; the drawing 
layer is dynamically linked to postGIS with a windowed Area Of Interest.)

Thanks.
