{{Note | These rows need to be investigated '''manually''' but most likely both distance . I have seen cases where Benchmarks have Distance <nowiki>= 0</nowiki> and Bearing <nowiki>= 0</nowiki> and bearing should then they may be deleted. Most likely they also have length(frompoint_guid) <nowiki>= 0</nowiki> too. But of course if they are part of the polygon or have FromPointGUID they cannot be deleted. Bearing <nowiki>= 0</nowiki> is OK (the same as 360 i.e. turn around) but Distance <nowiki>= 0</nowiki> is a user mistake that should not be deletedcorrected. NAA has UPDATE queries.}}
