Re: [Talk-GB] Talk-GB Digest, Vol 78, Issue 10

2013-03-14 Thread Fozy 81
We've discussed core paths before at various openstreetmap meetups in Scotland. 
The issue is that the paths are produced on OS maps and the data is not 
necessarily open. In the main, these paths are not signposted or at least 
signposted as core paths. There appears no way in good faith to reproduce the 
core path routes without copying OS copyrighted maps.


Also all the data is handled by individual councils. The advice was to perhaps 
ask one council for the their data and ask them to get it exempted from the OS 
copyright. Hopefully the other councils will fall like dominoes after that.



Any fancy a pet project?...

 I think I understand what councils have to do for public rights of way in 
 England and Wales.  However, I don't understand the situation concerning 
 rights of way in Scotland.  I would like some help, please.
 
 What kinds of paths are there in Scotland?
 I've seen mention of both rights of way and core paths.
 What's the difference?
 Who are the authorities that have legal obligations?
 What legal obligations do they have?
 Do they have to maintain a definitive map?

 According to the government site below in Scotland the local authorities
 don't have to signpost or record the Rights of Way:
 https://www.gov.uk/right-of-way-open-access-land/public-rights-of-way
 
 The paths are recorded and signposted by the charity Scotways where there
 appears to be plenty of information:

[Talk-GB] Calling all projection experts: WGS84 parameters

2013-03-14 Thread Steve

Hello fellow OSMers

A hopefully straightforward newbie question for you...

I'm currently uploading various new polygons via shapefiles created in 
Quantum GIS.  These use the WGS84 (EPSG:4326) projection, which Quantum 
defines as:


+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs +towgs84=0,0,0

A fellow mapper is doing similar, great stuff mapping administrative 
boundaries (Parishes etc) from Ordnance Survey, and setting the 
projection with the following parameters:


+proj=longlat +ellps=WGS84 +datum=WGS84 +zone=30 +no_defs

Because of the different parameters (i.e.  I have +towgs84=0,0,0, and he 
has +zone=30), there is a slight offset in data we are creating in the 
same areas.


The question is: which one of us is correct?

Thanks for your help

Ordnance Survey data is (normally) EPSG:27700
OpenStreetMap is: EPSG:4326

Zone is used for creating an offset origin point. Doubt that is what
you want...

Set OSM as a background layer in QGIS:
