fiinally I found some OSM sources and could extract some streetlamps of Aspen, Colorado.
It takes some manual formatting of the XML file, but I'm sure, this can be automated.
Feeding about 470 lamps into IPACS generic tool I had instant success.
Of course this will be made public as soon as the workflow has been established.
The major problem (at least for me) is to find useful OSM data.
So I ask again: Can someone provide OSM data in either ESRI shape format or any other text format?
