Just to highlight some mapping ITO have just released
[http://hs2maps.com/], which was developed with CPRE showing the
construction, landuse and operation impacts of the High Speed 2 line.
... Would be great to get more detail into OSM along the route, in
particular footpaths and heritage details so the project is based on a
thorough understanding of the impacts. We will update the maps from time
to time, and use the latest OSM data when we do so.
If you wish to detect which public rights of way (PROWs) are close to the
route of the proposed HS2, my web site http://www.thehs2.com may help.
www.thehs2.com can be used to display a map showing:
the route of the HS2;
the PROWs that are close to the route of the HS2;
the points at which these PROWs cross the route of the HS2.
The underlying map can be from the Ordnance Survey, OpenStreetMap, Google
or Bing.
Examples are:
Phase 1 (from London to the West Midlands):
http://www.thehs2.com/phase1/maps/showmap.php?place=South%20Heath&type=rcOSM&lat=51.705&lon=-0.677&zoom=13
Phase 2 (from the West Midlands to the North West and the North East):
http://www.thehs2.com/phase2/maps/showmap.php?place=Culcheth&type=rcOSM&lat=53.45&lon=-2.52&zoom=13
Those web pages show a map from OpenStreetMap with various items
superimposed on the map:
a multi-coloured line that shows the route of the HS2;
some cyan coloured lines showing the route of PROWs;
some circles showing crossing points (i.e., where HS2 and a PROW meet).
You can click on any of these items to get more details about the item.
www.thehs2.com provides information about PROWs close to the HS2 as
follows:
Phase 1:
Only for those PROWs which I've walked. This is all but two of the
crossing points between Euston and Offchurch (near Leamington Spa).
Because of my GPS device, this data is inaccurate in places.
Phase 2:
Only for those PROWs where the council has released data about their
PROWs. This is actually most of the PROWs as only the councils of
Manchester, Sheffield and Trafford are unable to supply data.
The data is also available in KML format:
Phase 1:
crossing points: http://www.thehs2.com/phase1/kmls/c/all.kml
PROWs: http://www.thehs2.com/phase1/kmls/r/all.kml
Phase 2:
crossing points: http://www.thehs2.com/phase2/kmls/c/all.kml
PROWs: http://www.thehs2.com/phase2/kmls/r/all.kml
The crossing points are also available in csv files:
Phase 1:
http://www.thehs2.com/phase1/kmls/c/all.csv
Phase 2:
http://www.thehs2.com/phase2/kmls/c/all.csv
In these csv files, the word "Fill" means "embankment" and the phrase
"At Grade" means "level with the nearby land".
So these maps/data may help you find the PROWs which cross the route of
the HS2 that are missing from OpenStreetMap and so need some mapping done.
