Key to Queensland four mile map series, 1915. In June 1915, the Surveyor General presented his annual report on mapping and surveying activities in Queensland. This included a map of progress conducted over the last year on the four mile to an inch, or ‘four mile’ map series. This map included the location of stations used for calculating latitude and longitude and provided a table of town coordinates established by astronomical observation. The area covered by major triangulation was limited to south east Queensland. Queensland parliamentary papers, Vol 2, 1915-16
