Geoscience Australia

Pre 1943 imagery is also available for Sydney at but has not yet been orthorectified.

It appears the custodian of the 1930 imagery is with Geoscience Australia which per releases all of it's material under CC BY 4.0.

Tagging date ranges from imagery

When historical mapping from imagery features might either:

  1. Pre-exist the earliest imagery. In this case we don't know the start_date, but know that it at least existed by the year of the imagery. Fer example if an object is visible in the earlist imagery source from 1943 then tag this as start_date:edtf=..1943.
  2. Not appear in an earlier imagery but appear in a latter one. In this case we know know a range of the possible start_date. For example if an object is not visible in 1943 but then appears in 1955 then tag this as start_date:edtf=1943/1955.

Similarly for the end_date.

Because OHM does not yet support start_date:edtf=* and end_date:edtf=* you should still also add regular start_date=* and end_date=* when you would have used a range (/) based on the closest known date the feature started or ended.
