Highway intersects water	Highways that overlap with water geometries/features	Align the highway/water geometry based on imagery
Impossible one-ways	One-way roads where you can't get to the start point	Make appropriate connections between existing ways with imagery as the source
Loopings	Roads or buildings that have two joined nodes that make a self intersection
#MapLesotho - Track Assessment	Confirm the highway=track tag in roads	Correct the highway=* for an appropriate value.
Misspelled tags	Geometries with incorrect key-value pair	Correct the tag for appropriate values
Mixed layers	Nodes that is a junction of ways with different layer properties	Remove the junction for ways in different layers
Small components	Unconnected islands of road networks	Make appropriate connections based on imagery
Roundabout USA
Strange layer	Bridges with a negative layer and tunnels with postive layers	Correct the layer tag
Tiger delta	Tiger roads that are not available in OSM	Add the roads
Unconnected major	Motorable roads that end near another road but not connected to it	Join disconnected roads and junctions verifiable from satellite imagery
Unconnected minor	Paths and tracks that end near another road but not connected to it	Make appropriate connections based on imagery
Unconnected paths
