comment How to apply colour ramp to user-defined range of values for contour lines?
Yep - I think that, in the absence of a configurable mechanism, this is an expedient way to go; what I may do is to merge two tiles that span the entire altitude range (in Scotland, from 0 to ~1400m ASL), generate the style, and apply to each tile.

comment How to apply colour ramp to user-defined range of values for contour lines?
Good suggestion - I've checked that one: it still doesn't provide a means to generate the styling beyond the range of the current dataset. I'm thinking I may have a go at writing a plug-in - unless someone comes back with a viable method using existing tools.

comment How to apply colour ramp to user-defined range of values for contour lines?
Hi - that had occurred to me but... I only want to use a subset of the total data library at one time, so would rather keep them as separate tiles. Also, this does not represent a generic solution. I looked at editing a saved QML file, but that becomes infeasible for large numbers of categories with fine gradations of colour change.

The rover and base station GPS data (presumably WGS84) were post-processed to DGPS using OS RINEX station corrections to produce National Grid eastings and northings with height AODN.
