Hi All,
I appreciate it is something we don't necessarily map, but has anyone seen
any gas/oil marker posts on their travels? I am interested in the
sub-surface layout
Me too --- I've been mapping quite a few powerlines, and would like to
get pipelines but haven't managed to spot many.
and wonderered if anyone had seen any markers that they
could let me know about.
I noticed something on the road going north-east from Six Mile Bottom
(maybe around
http://www.openstreetmap.org/?lat=52.1985273063183lon=0.28215765953064zoom=18
but I can't remember exactly), I think it was a white-and-orange
banded post; I've been meaning to go back and investigate. There's a
gas compressor station fairly nearby
(http://www.openstreetmap.org/?lat=52.1847850084305lon=0.270532965660095zoom=18)
and I suspect it's connected with that.
At
http://www.openstreetmap.org/?lat=52.2105194628239lon=0.259908735752106zoom=17
I found a water pipeline (which I've tagged; it's visible on
osmarender but not mapnik) as there's a marker sign (like the fire
hydrant signs, but blue) where it crosses the road, and there's a
marker post where it meets the track going southeast from the road. I
traced it as far as I could from the bing photos, as it shows as a
disturbance in the fields.
There's some kind of pumping station at
http://www.openstreetmap.org/?lat=52.1787299215794layers=Olon=0.295938849449158zoom=17,
and I could see a faint mark on bing showing a pipeline leading to it
(again visible on osmarender). I suspect that one's water, as it
leads close to the Fleam Dyke Pumping Station, which is a groundwater
extraction plant.
There's a big gas pumping station at
http://www.openstreetmap.org/?lat=52.4599286913872layers=Olon=0.842409431934357zoom=17
and again I managed to deduce a short section of pipeline from bing.
Any of these might be useful starting points for looking for posts.
I'll go back to the Six Mile Bottom road one in the next few days and
get the exact location (it's within a couple of miles of my house).
I also remember someone mentioning a gas pumping station near Duxford,
so that might be a good place to start looking around for posts.
