Overpass API/Overpass API by Example/QA Tool Overpass Queries

Many of these can be used in conjunction with JOSM Validator Rules that may offer autofixes for the issues.

Validation Query	Description	Reference
Boundary Missing Source	An administrative boundary does not contain tag source=* sourcing the origin	OSMOSE 2040: Source
Building Road Intersection	Flags buildings that intersect/touch center lines of roads. This does not address cases where buildings get really close to roads, but do not overlap them.	Atlas: Building Road Intersection
Combinations	Missing tags on a given combination, suspicious tag combinations	JOSM: combinations
Deprecated Tags	Deprecated tagging that needs to be updated	JOSM: deprecated
Elevation	Some elements, including the peak (natural=peak) and mountain_pass (mountain_pass=yes), has an evelation. This is shown in OSM with tag ele=* in meters.	OSMOSE 2020: Elevation
fixme	Items tagged with fixme	KeepRight 170: fixme tagged items
Geometry	Incorrect geometry used or topological issues	JOSM: geometry
Highway	Highway validations	JOSM: highway
Missing Highway	The way seems to be a highway=*. Class 20800 "Tag highway missing on junction" : the way have a tag junction=* but without highway=*. Class 20801 "Tag highway missing on oneway" : the way have a tag oneway=* but without highway=*. Class 20803 "Tag highway missing for tracktype or lanes" :	OSMOSE 2080: Missing Highway CLASS 20800, 20801, 20803, 20804
Missing Oneway on Motorlink	Detecting motorway links without oneway tag , which is connected to a highway=motorway with a oneway	OSMLint: missing oneway on motorway link
Orphan Nodes	Untagged nodes that do not belong to a way
Place without Name	The tag place=* must always be used in combination with the tag name=*.	OSMOSE 6030: place without name
Powerlines	This analysis mainly verifies the continuity of powerlines Class 1 "Lone power tower or pole" :	OSMOSE 7040: power lines Class 1
Relation	Relation validations	JOSM: relation
Tunnel and Bridge without Layer	This validator detects all the bridges that does not have the tag layer=*.	OSMLint: tunnel and bridge without layer
Tunnel/Bridge Max Height	Missing maxheight=* or maxheight: * for a tunnel or a way under a bridge.	OSMOSE 7130:Tunnel/Bridge
Two Names	tag name=* contains two street names, separated by a semicolon, a "/" or a "\". This issue was probably produced by the fusion of two way and the concatenation of the names of streets.	OSMOSE 5030 - Two names
Unnecessary	Features with unnecessary tags that can be removed	JOSM: unnecessary
Wrong Highway on Roundabout	Class 1 "Wrong highway on roundabout" : it must match the highest level of connected routes, except highway and trunk.	OSMOSE 3010: Class 1 wrong highway on roundabout
Wrong Railway Crossing	Checks level crossings if all ways have same layer=* and any way has tag bridge=* or tunnel=*.	KeepRight 160: Wrongly Used Railway Crossing Tag
