HS2

BP Brian Prangle Public Seen by 265

HS2 is already gobbling up land and starting enabling worksin Birmingham. I attended a public communications event about Curzon Street station (the HS2 terminus in Birmingham) the other week organised by the Community Engagement Team of Laing O'Rourke and Murphy and had a long discussion with them about engaging the OpenStreetMap community. The upshot was that they would investigate how to work with us, particularly as I could demonstrate the following day after they took possession of another lalrge car park that our map was updated within an hour.

They also gave me information about the HS2 Community and Environment Fund which might be worth investigating. There will be massive amounts of mapping work for us to do and ny fear is that it will probably overwhelm us as a community of volunteers as presently organised and this funding route might help us.
I see this as a great opportunity to demonstrate the power of OSM and also a great project for the UK Chapter to organise.

Never say never. When the Irish mapping community first started the townland mapping project, people said we were crazy and it would never get finished. When you work together and pool resources it is amazing what can be done and we have all 60,988 townlands of Ireland mapped and in the OSM database :)

The main issue that I see is getting access to imagery/GPS tracks/geodata for OSM to work from and making it available to the community to use under a compatible license.

I have a strong interest in HS2 mapping having previously built a professional product based on the data. HS2 Ltd were surprisingly forward-thinking with their Open Data.

As with all new construction it can involve manual surveying as aerial photos won't show them yet. There will also be difficulty gaining physical access to works areas. A level of 'officialness' from OSMUK might help.

All of the areas due to change should be outlined on the safeguarding maps as HS2 Ltd had to reserve the land and do planning assessments and the like. Safeguarding areas are published with OS backgrounds and may (or may not) have been plotted by tracing OS polygons.

Surely if they plotted using OS imagery/backgrounds or tracing OS polygons the resulting work would be polluted from an OSM license stand point?

Yes, that's what I was inferring.

The line route itself will have been surveyed and planned by HS2 Ltd and was released by them unpolluted.

The safeguarding areas can direct us to where new things are being built, which would need manual surveying.
