I’ve succesfully downloaded a .osm file with overpass-turbo. After that I have created a Garmin . gpi file using GPSBabel. I’ve manged to display benches on my Garmin device. I had to download a .bmp file (displaying a bench) and tell GPSBabel to use this. It is not exactly what I hoped for but I’ll have to dig into this a little more. Looks pretty good so far.
So far the procedure works fine for nodes. for example… all tourism=camp_sites (tagged as nodes) can be searched on my Garmin device. I can even have GPSBabel make the “name” tag visible in my searchable POI list.
There are also camp sites that are mapped as ways (area). If I want to make a POI of these I see an item for every single node in this way. The name tag can not be displayed because that is a tag of the way and not of the seperate nodes. It would be nice if POI info of ways could be converted to one singel node (center point is calculated) and also include the name of the way. Does anybody know is this is possible?
