Thank you. I used ASIG for the numbers/street names and ESRI for the building outlines, and a mixture of both for the image offset. I assume that the OSM/ASIG licenses are compatible, but I haven't checked this. This means that all mapping efforts will be undone if someone decides that this is an illegal data import. I usually do this, but the reason I haven't checked is that I don't understand Albanian and many of the legal documents are written in Albanian. To minimize this risk, one approach is to separate the mapping (land use, buildings, roads) from the addresses. I proceeded as follows with the mapping. 1. I use the roads in ASIG as ground truth. There, I also check whether they are largely covered and fill in any gaps. For roads that have a name, I assume highway=residential in the local environment. 2. Based on the mapped roads, I look for the satellite images that have the highest orthogonality (90 degrees from above). There I draw the building outlines. This is best done in the id editor in grid mode (key 'W'). I always make the outline rectangular with the 'Q' key. Since I don't know what a residential building in Albania typically looks like, all outlines get building=yes. 3. I add the addresses (only addr:street + addr:housenumber via the ASIG layer) and transfer them to the address field of the building outline. The city and postal code are usually resolved via the admin relations, so they are unnecessary. For buildings that are difficult to draw in several parts and have several different addresses, I also set separate address points. However, I think addresses belong on the outline. This also leads to better integration in the browser/editing tool. Sometimes you have to zoom in and out of the ASIG layer to see the house number. Sometimes it is relatively difficult to see which street the house number belongs to. It is best to look for 1 and 2 at the beginning of the street and then work your way up.
That's how I did it. Feel free to ask if you need support.
