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out-of-date (and the poor registration between the rights of way GIS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.
