[OSM-dev] OpenstreetMap Trace Analysys

[John Robert Peterson]

There is a massive difference between knowing what area somone lives in and
knowing thier exact address -- I'm happy with people knowing which housing
estate I live in -- if somone wants to come to the area just to find me --
they will have to knock on 300 doors (t-888 style).

However from traces that are up there, it's posible to find the large bush
that surrounds mappers houses -- reducing this to about 5 doors, that does
worry me.

This (among other things) is why i've put a lot of effort into writing a
script to process traces, I now exclude an area a few hundred meters across
from all of my uploads, this gives me enough anonymity to put up with the
situation, I'm still not all together happy with it though.
