Cleaning Up Errors, i.e. Almost junctions and missing junctions
Skrevet af mannequinZOD den 2 november 2009 på EnglishCleaned up more than a 100 mapping errors (only missing junction nodes) in the Cambridge, UK area, one of the 'better' mapped places. There are still plently left further outside the city.
Look at http://keepright.ipax.at/ and display all junction errors in your neighbourhoor. You will be surprised. The rendered map might look quite nice already, but it's ugly underneath

Do you know how often the database of errors is updated? It would be nice to know how often to check back.

It's probably only a few, but how do you know that some of these 'almost-junctions' are not actually two separate nodes and which don't form a junction? It's not really worth mentioning, but if someone used routing software, it's better to not route them somewhere where a mapping error has been made -- albeit a slight one and probably accidental.

you have to be indeed careful. Working on an area you know or having satellite images helps :-) In doubt, don't 'mis'fix it.
