I produce printed maps out from OSM-Data. While I work with the osm-data, I find some missing places, names or something to fix and I would like to change/add it to OSM directly. But for several reasons I have to do my Work with a local OSM-Copy (osm2pgsql).

My work flow: I download the OSM-Area of interest and import it into a local PostGIS database. Then I do some SQL queries to fit my needs. I style and edit with QGIS. If I have to correct something, I do it on my local DB. At last the result will be printed...

I'm looking for a new work flow, so that my changes and adds are uploaded to OSM, so that anyone else can use it!

I could do my changes directly to OSM and wait at least one week to download the updated data. For some large-scale projects I do that already, but my small scale works have to be just in time - I often can't wait for the next OSM extract.
