No model is involved in the drawing. Every line is placed by code from a
government dataset, so the same address always produces the same sheet.
How it works
geocode
The address is matched against the NSW address register, then the
cadastre gives the lot boundary. Multi-lot sites are combined into one.
gather
Zoning, height and floor-space controls, heritage, terrain, roads,
transport, aerial imagery and street detail, for the area around the site.
compose
Projected, scaled and drawn to the office standard, with labels placed
to avoid collisions, then printed to a print-ready A1 PDF.
export
The same geometry in DXF, real-world metres on the MGA2020 grid, one
layer per data class, ready to underlay a survey.
Data sources
NSW Spatial
Addressing, cadastral boundaries, roads and rail, elevation and
contours, aerial imagery

Zoning, height of building, floor space ratio, minimum lot size,
heritage items

Bus stops and route information
OpenStreetMap
Bus and light-rail routes, trees, driveways, kerbside parking, street
furniture

What it does not do
not a survey
Boundaries come from the cadastre, a mapping approximation. Site areas
typically differ from the surveyed figure by a few per cent. Levels come from a 1 m
elevation model.
not a s10.7
The controls shown are the mapped LEP layers. A planning certificate
from council is the authoritative document.
no DCP
Council setbacks, landscaped area and parking rates are not published
as open data, so those rows are left blank to complete by hand.
OSM varies
Trees, driveways and parking are volunteered data and vary in
completeness between suburbs.
coverage
New South Wales, Australia. Sydney basin addresses resolve fastest.
