[Talk-GB] NLS crowdsource projects and more OOC maps

[Michael Booth]

Thanks for the update Rob. I signed up for this but not had a chance to 
do any tracing, good to know it's going well.

What would be great is if there was a way to compare OSM highway data 
with the NLS footpaths so that missing paths in OSM can be found. 
Similar to how the old OS Locator found street names which were missing 
from OSM?

Strava's heatmap could also be incorporated into such a tool, 
highlighting missing paths which are actually used by people on the 
ground. A maproulette task could then list these paths - would be easier 
than going around Scotland looking for missing paths!

Their newsletter update has a link to the data available for download in 
KML format, and NLS say they "are creating free, open and 
publicly-available data for re-use" so I'm assuming it could be used in OSM.
