Aside from the automatically dropped tags there are:
tiger:cfcc tiger:county tiger:name_base tiger:name_direction_suffix tiger:name_direction_prefix tiger:name_type tiger:reviewed tiger:zip_left tiger:zip_right My practice is to drop county if the county relation exists and is valid, cfcc if I've reviewed or changed the highway=* classification and tiger:name* tags if I've expanded the name. cfcc is the only one that requires explanation of the meaning. This is the road classification within TIGER and was used to determine the initial highway=* value but cfcc does not map to highway=* values particularly well. I wouldn't give this much weight, you can often do better from aerial imagery than the TIGER classifications. They're particularly off for forestry roads. I never know what to do with tiger:reviewed or the ZIP tags. If I've removed all of the TIGER tags but still feel the source to be TIGER I add source=TIGER 2005 From: Henning Scholland [mailto:[email protected]] Sent: Tuesday, November 20, 2012 2:10 AM To: osm Subject: [OSM-talk] obsolete TIGER-tags Hi, because of Operation Cowboy many users will become into contact with TIGER-tags and don't really now ho to deal with them. There are: tiger:cfcc tiger:county tiger:name_base tiger:name_direction_suffix tiger:name_direction_prefix tiger:name_type tiger:reviewed tiger:seperated tiger:source tiger:tlid tiger:upload_uuid tiger:zip_left tiger:zip_right Which of above tags are obsolete and should be removed after checking the object against aerial image and gps-tracks?
