Thanks. Have you had any trouble getting the tiles to load in JOSM? When I
tried I keep getting error messages popping up which made it unusable. JOSM
does seem to suffer from bugs these days (maybe I

Ed,
Is it possible to add Bing aerial as a layer - it would be interesting to
see how it compares for tracing. I'll check it out in JOSM but others may
like it on the website.
Cheers,

Hi Tony,
As OS OpenMap is vector data, finding the height for any building
outline would be similar to using OSM building outlines. Using the DTM
data would also give the base height AMSL of the building.

landscape to matc
Hi Chris
Would it be possible to somehow use this data with the building
outlines from OS OpenMap?. I know that data is somewhat
simplified/generalised, but maybe combined together we could get an
idea of how the simplified shapes from OS OpenData are terraced and
even get their heights. I'm not t
Sounds good Chris.
No problems with imports from me (assuming the data passes reasonable*
quality assurance). I do feel that the concerns over imports are preventing
OSM from properly innovating. This is a good example of dataset and an
innovative approach that has been made available to us. It wo

It looks excellent, at least at first glance. Thanks so much for all the
work.

It might well do that. I'll attempt to compare two areas tomorrow and
see how easy it is get any height data out. As it happens, one of the
areas covered by the EA data that I have worked on is a large village
