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though inevitably out-of-date (and the poor registration between the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.<br>
