Finally managed to get something 'believable', see attached contours. You can download the corresponding roads with JOSM.

Problems where:
1) GnuPlot output number format didn't have enough digits and was distorting data.
2) Gnuplot dgrid3d needed to be tweaked to improve rejection of points further away.
3) Source data didn't contain enough nodes, had to interpolate

So I need to merge and render this out with Osmarender, which shouldn't be too difficult. And then write it up in some form for others to try.

I'd also like to look at selecting which ways to route down. At present it looks like it is fixed in the perl script but there are some it shouldn't use ('access=private') and it would be nice to do two maps, one with stairs and one without (mother pushing pram...).

Cheers,
Simon.
