There's nothing more fascinating (well to me!!) than visual research tools.
I love time lines and I love old newspapers online and now I love SIX maps. You'll find them at http://maps.six.nsw.gov.au/
The New South Wales Government has made available aerial maps of Sydney and part of their basemaps include photographs taken from 1943.
It is fascinating to chose the maps and then move the slider toolbar up and down to see how things have changed in 70 years.
Look, at for example this view above Enmore Park and Marrickville Metro Shopping centre. It is a fairly recent photograph showing the newish Aquatic Centre and Metro is busy with a lot of cars parking on their upper level.
Vicars mills were a huge operation. We can see that their buildings took over the entire Marrickville Metro site.
We can see the building next to Bethsheda Nursing home didn't exist either in 1943.
I can imagine this tool would be perfect for helping to discover answers to a number of mysteries. It's a shame the zoom isn't extensive .. and oh imagine how wonderful if we had Street View for 1943.
I hope you enjoy this time machine as much as I have been. What mysteries will you uncover?
