(issue1772) Use 0.001km tolarance instead of 0.1 to find matching km. There is no sense to use a define here. I will not write static final double NULLPOINTNULLNULLONE=0.001 if i just want to use that value and not any other value which may make sense in some other place. Using hardcoded values can have its merits and makes the code easier to read.
