I have been examining the data marked as something that will be lost in 
an area fairly close to me. Much of this was created many years ago and 
the original editor has not responded to attempts to contact them.

Much of this is based on poor-quality aerial imagery. Replacing it with 
a survey or even more recent imagery creates much higher quality data, 
not least better geometry. I have gone on to improve other work 
sometimes by adding extra detail for example roundabout flares, road 
names (from survey or other open sources) and adding otherwise missing 
roads, tracks etc.

Like-for-like replacement might not be useful, but much of this is a 
positive improvement and worthwhile in its own right. I might not have 
looked at some of these areas without the process of licence change. I 
will now be reviewing the whole area (northern Lincolnshire, UK) over 
the next few months and I expect to find lots of potential improvements, 
just like anywhere else.

Cheers, Chris
