I use OSM-data for the development of an population disaggregation algorithm. In order to improve the results I want to add missing attributes to some of the buildings with an OSM-editor. I am identifying these buildings in PostGIS. As I want to map the features directly in OpenStreetMap, I am currently looking for an efficient procedure to have an OSM-file with the buildings (from PostGIS-table), which I can then load into JOSM for mapping.
I read some other posts discussing the export of PostGIS-tables with Osmosis. (Using osmosis to convert POSTGIS Table to .OSM)
I however have the doubt and fear that some OSM-information will be lost and accordingly when the updates are pushed to OSM the OSM-dataset will be harmed. Are there any best practice workflows or recommendations for accomplishing this tasks?
