Hi Malcolm,
I created contours from the UK Environment Agency LIDAR and wrote a post
about it
here:https://chris-osm.blogspot.com/2015/09/more-lidar-goodness.html I'm
not sure if this helps. GDAL stuff is useful.
The relief map is missing the road overlay now as the MapQuest roads
layer is no more, but with the water overlay you can see the detail
well. It is for Hull, which I believe you know well :-)
Cheers,
Chris Hill (chillly)

Does anybody know of software to convert depth/elevation data in
ESRI-ASCII format into contour vectors, preferably as OSM polygons?
