SITE ANALYST

GENERATE A DRAWING

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.
deck
The overall-analysis slides: A3 pages of small maps and tables for the content part of a feasibility study or design report, all eighteen of the spec: location, the site in its region at 1:75,000 with the plan's centres, the stations and 2 and 5 km rings — character, Wikipedia's summary of the suburb, the places nearby with articles numbered on an aerial, and open-licence photographs from Wikimedia Commons credited as their licences ask — the planning pair — zoning, heights, heritage and housing-policy maps around the site, and every mapped control at it with its source — strategic context, the documents over the site from the State Land Use Plan and The Sydney Plan to the council's local strategic planning statement, the plan, the DCP and the contributions, one line each with links — topography, a hillshade with contours and two sections through the site — built form, the footprints around the site by height (a determined DA's storeys where the sources have none, hatched) with the LEP height plane on the section — movement, the streets, rail, bus, cycleways and walking reach around the site — green and public domain, the parks, Green Grid assets, facilities and street trees around the site with the 2022 tree canopy by mesh block — environmental constraints, the hazard, protection, coastal and corridor maps around the site with a definite answer for every layer — Country, the pre-1750 plant communities over the land's shape with the watercourses, crests and gazetted Aboriginal Places, the Aboriginal heritage permits, listings and mapped landscapes over it, the land council and native title registers at the site, and the statement that AHIMS is not open — the site, the site plan on the aerial with its dimensions, levels, existing footprint and a facts table, and the block with the recent sales and the public land around — existing site condition, the open street-level frames that look at the site keyed to a plan of the cameras, the 1943 aerial survey beside today's imagery over the same ground, and placeholders for the site visit's photographs — grid, sun and views, the street bearings as a rose, the sun path computed for the site, the neighbours' winter shadows over the site at 9, noon and 3, the sight lines to the skylines, water and parks, and summer and winter wind roses from NASA's reanalysis — development activity, the applications of scale lodged around the site in the last five years and the State significant applications from the Department's register, on a map and in a table — and people and market: the census profile of the site's area against the city, population and projections, land values and sales, the nearest schools — and opportunities and constraints, two diagrams around the site assembled from the layers the other slides fetched, with numbered statements the data supports for the author to edit — and sources, every dataset the deck read with its currency, retrieval time and attribution, what is computed rather than sourced, what is still to obtain, and the run's warnings. The author's narrative is left as placeholders.

Data sources

NSW Spatial
Addressing, cadastral boundaries, roads and rail, elevation and contours, aerial imagery, water bodies and coastline, and the 5 m elevation surface the sight lines are tested against; for the deck the same model as a grid, for the hillshade and the sections, the site plan's aerial and boundary lengths, the easement geometry and the neighbours' numbers, the street bearings and the sight lines to the skylines, the named water and the coast
City of Sydney
Inside its area: the council's tree inventory (height, canopy spread, species) and 1 m contours from a 2020 aerial survey, both CC BY 4.0
ePlanning
Zoning, height of building, floor space ratio, minimum lot size, heritage items; for the deck also the Planning Portal's property report, the Housing and Planning Systems SEPP maps, DCP and contributions layers, the State Heritage Register, planning proposals on exhibition and the Online DA feed of applications lodged with the council; the Major Projects register of State significant applications, read from its listing and project pages
councils
Where a council publishes its DCP mapping as open data (the City of Sydney), the deck reads building heights in storeys, frontage heights, active frontages and setbacks from it
TfNSW
Bus stops and route information; for the deck the Travel Zone Projections 2024 of population to 2066
ABS
For the deck: the statistical regions at the site, Census 2021 tables, the population series since 2001 and SEIFA 2021, from the ABS SDMX API
Valuer General
For the deck: the land values of the site and the sales register around it, through the SIX Maps valuation service
NSW Education
For the deck: government school locations and enrolments
Overture Maps
For the deck: building footprints with heights and storeys, read from the foundation's public bucket; OpenStreetMap stands in where they cannot be read
OpenStreetMap
Bus and light-rail routes, trees, driveways, kerbside parking and car parks, street furniture
ePlanning (movement)
For the deck: the LEP's active street frontages
ePlanning (green)
For the deck: the Greater Sydney tree canopy of 2022 by modified mesh block (canopy and vegetation-height shares), the Green Grid's existing assets with their class and significance, and the open-space and public-facility points
NPWS estate
For the deck: the National Parks and Wildlife Service estate, from the department's managed-land layer
ePlanning (constraints)
For the deck: the plans' own hazard and protection maps (flood planning, landslide, acid sulfate soils, salinity, mineral land, groundwater vulnerability, drinking water catchments, riparian land and watercourses, wetlands, biodiversity, environmentally sensitive and scenic land, airport noise, obstacle limitation surfaces), the RFS bushfire prone land map, the coastal maps of the Resilience and Hazards SEPP, the rail corridor and future infrastructure corridors of the Transport and Infrastructure SEPP, and Subsidence Advisory's mine subsidence districts; where a plan's map is empty in the window, a plan-wide count says whether the plan has such a map at all
NSW soil landscapes
For the deck: the soil landscape at the site from the Sydney 1:100,000 sheet, the one published as a service
ePlanning (land)
For the deck: the State government land parcels (GPI) and the Crown land and Crown reserves layers, for the public land around the site
Country layers
For the deck: the National Native Title Tribunal's registers of determinations, claims and Indigenous land use agreements; Heritage NSW's gazetted Aboriginal Places and Aboriginal Heritage Impact Permit boundaries; the LEPs' scheduled Aboriginal items and their maps of Aboriginal cultural landscapes (ePlanning); the Indigenous places of the National and Commonwealth Heritage Lists and of the Register of the National Estate, an archive since 2007 (DCCEEW); the State Vegetation Type Map's pre-1750 plant community types and the Aboriginal Sites Decision Support Tool model (DCCEEW); the water theme's watercourses and coastline and the Local Aboriginal Land Council areas (NSW Spatial Services). AHIMS is not open data and is never read; the slide says a search is required
NSW Imagery dates
For the deck: the capture date and resolution of the aerial under the site plan, from SIX Maps' imagery-dates layer
Wikipedia and Wikimedia Commons
For the deck: the suburb's article as the seed text (CC BY-SA 4.0) and the articles placed within 1.5 km; the geotagged photographs within 800 m with their author and licence, each credited under its frame
The Sydney Plan and the Planning Portal
For the deck: the centres of The Sydney Plan (2026) and their types, transcribed from its Appendix D into a table in the code; the planning region at the site from the Department's boundary service; every council's local strategic planning statement from the Portal's index page
Street-level and 1943 imagery
For the deck: Google Street View frames of each street frontage, found with its free metadata service and credited under each frame; KartaView's frames within 250 m of the site with their camera positions and headings (no key; CC BY-SA 4.0, the contributor named under each frame), Mapillary's when a client token is set, and the 1943 aerial survey of Sydney from Spatial Services' Historical Imagery tile service beside today's imagery over the same ground
NASA POWER
For the deck: the hourly wind at 10 m over the last five years from the MERRA-2 reanalysis (the NASA Langley Research Center POWER Project), counted into summer and winter roses; the region's wind, not a measurement at the site
Valhalla
5 and 10 minute walking catchments

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 are read between the mapped contours, 1 m apart where a council publishes them and 2 m elsewhere.
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.
tree sizes
A canopy is drawn at its recorded size only where a council publishes one. Elsewhere it is estimated from a tagged height or trunk, or a nominal 6 m drawn dashed.
parking bays
Kerbside bays are set out at standard sizes along the kerb the cadastre implies, where OpenStreetMap tags the street. The count is kerb length over bay length, not a survey of the line marking.
views
A potential view is a sight line over the ground only, from just under the height limit. Buildings and trees in the way are not open data, so confirm on site. The deck's winter shadows are cast from footprints and recorded heights only, not a model of the block; the sun positions are computed, not measured.
coverage
New South Wales, Australia. Sydney basin addresses resolve fastest.
