Here's an interesting thing:
Locate Potteric Carr Nature Reserve (just south of Doncaster in JOSM
(or your other favourite, suitable editor) and view Bing aerial
imagery.
With the slider set midway, note the lush green marshes.
Zoom in - and eventually, the marshes, buildings and paths disappear
and you can see the reserve under construction.
Clearly, the different levels of zoom are using different
time-separated sets of imagery.
It would be cool if the reserve's managers, Yorkshire Wildlife Trust,
could make use of the visual comparison. How might this be done?
Does anyone have other note-worthy examples of this phenomenon?
