France, Belgium and the UK now offer free access
to their databases of trigonometric points for their triangulations:

(zoom in, then open Sites Géodésiques in the left window)

(select an area)

(query by 1:50000 map sheet number) from

If anyone knows of other countries anywhere in
the world offering similar free access to their
triangulation point database, perhaps in response
to the European Union INSPIRE directive which is now in force,

please post the links on this list or send them to me off-list if you prefer.
