Can anybody point me towards the following please?
My starting-point is a database in which each field includes images and
text as well as spatio-temporal coordinates, including at least one "on ...
off" pair.
The output required is a map and a slider such that as the slider moves,
each image appears at its relevant spatio-temporal position(s)- i.e. if the
place is London and the on-off dates are 1910 and 1920 then the image will
show at London iff the slider is between 1910 and 1920.
Sounds easy - but I have not the foggiest idea how to do it!
