Hi Barry,

This is all very useful and clarifies some issues for various datasets.

I and others have indeed been using rowmaps data in the way you suggest: as
a tool for planning surveys.

I still think it's a shame that councils are so reluctant to clearly state
the nature of licences on their own websites, and rely on you to perform
this service with the inevitable issues of introducing more steps which is
already complicated by the different roles of LAs/OSGB.
