[Talk-GB] OS, OSM and field boundaries

[Mike Harris]

Although the OS has at last been forced into releasing some data we have 
paid for, it is still withholding field boundaries (as per OS 1:25k). 
These are invaluable for footpath walkers in agricultural areas (i.e. 
most of England and parts of Scotland and Wales) even though inevitably 
out-of-date (and the poor registration between the rights of way GIS 
layer and the base mapping can all too often leave you backtracking 
after walking a few hundred metres on the wrong side of the hedge!). 
Clearly most boundaries cannot readily be surveyed on the ground by OSM 
workers (short of triangulation) although satellite mapping is a big 
help where licence-free and clear enough. (Nick and others - thanks for 
the great work). Sadly I still cannot really use OSM for footpath 
walking away from conurbations. On a smart phone the zoom limitations 
make the OS 1:25k mapping of limited use (although Multimaps' OS version 
is better). Google satellite mapping is often too dark to read out of 
doors (and tiles cannot be downloaded for outdoor use because of 
Google's "fair usage" terms - as I have learned the hard way after 
having my IP address blocked by Google for 24 hours!); Google Maps is of 
little use out of town. What is needed in OSM for walkers - but how to 
do it? (thanks to Nick and others for great work) is (a) contours and 
(b) field boundaries.
