It has been proposed that this page be moved to "Error categories". (Discuss) |  |
This page contains a list of error categories, how you can find those errors and how to correct them.
Table
| Picture | Category | Severity | Find | Correct |
|---|---|---|---|---|
| Unconnected highway (touching) | This is a severe error when looking at routing applications. Connected roads are not connected in OSM data. | waychecks by gary68 | Connect nodes in JOSM with merge function | |
| Unconnected highway (open) | This may be a severe error when looking at routing applications. Is the highway really just ending there? | waychecks by gary68 | Connect nodes in JOSM with merge function. Or extend map. | |
| Crossing on same layer without common node | Either bridge or tunnel and layer is missing or a common node is missing. Either reality is not reflected correctly or routing cannot be done correctly because roads are not connected in data. | waychecks by gary68 | Add layer information and bridge/tunnel information. Or create common node! | |
|
Open areas | Reality is not reflected correctly and maybe some programs might have problems using those polygons. | areacheck.pl by gary68 | Close areas by prolonging the way. Last node has to be the same as the first. |
|
Oneway errors on motorways | Imaging you are sitting in a car navigated by OSM using this data... | motorwaycheck.pl by gary68 | Correct tagging and/or direction of way. Josm reverse way i.e. |
| Doubled nodes in ways | checkdouble.pl by gary68 | good question... | ||
|
Roundabouts with wrong direction | checkround.pl by gary68 | Reverse way with i.e. Josm or add oneway=-1 tag. | |
