Survey Datum
Robert Hoddle used Batman's Hill as the datum for the cadastral survey of the land around Melbourne from 1837. A grid of orthogonal Section lines at one mile spacing, aligned with magnetic north, divided the land into one square mile (640 acre) sections for subdivision and land sales. The section boundaries were adjusted for watercourses. The linear property boundaries, in the absence of pre-existing tracks, were natural locations for major roads. For example:
- Swan Street, Riversdale Road and Somerville Road are on the east-west section line that passes through the datum.
- Victoria Street and Barkers Road run east-west one mile to the north
- Alexandra Parade and Racecourse Road run east-west two miles to the north
- Royal Parade and Sydney Road run north-south along the section line passing through the datum.
- Hoddle Street runs north-south two miles to the east
- Springvale Road runs north-south twelve miles to the east

Famous quotes containing the words survey and/or datum:
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
“Language fails not because thought fails, but because no verbal symbols can do justice to the fullness and richness of thought. If we are to continue talking about “data” in any other sense than as reflective distinctions, the original datum is always such a qualitative whole.”
—John Dewey (1859–1952)
