Clarity from the Ground Up. Accurate Data. Smarter Design Decisions.

At Astra Spatial, we provide detail and identification surveys in Sydney — also referred to as feature or topographic surveys — to give architects, engineers, and builders the accurate site data required for confident design and construction.

Operating across Sydney, Greater Sydney and regional NSW, our licensed surveyors use advanced robotic total stations to capture all relevant surface and feature details on-site — from contours and structures to utilities and vegetation.

Why Detail & Identification Surveys Matter in Sydney

A detailed or topographic survey is the foundation for effective design and construction. It records every visible feature and level, allowing architects and engineers to plan with confidence.

A professionally prepared detail survey in Sydney or greater NSW ensures your design accurately represents existing site conditions — preventing costly redesigns, service clashes, and compliance issues later on.

Our team has supported everything from residential builds in North Sydney and the Inner West to major civil and infrastructure projects across the Hills District and regional NSW.

Our Sydney Detail & Identification Survey Process

1 | Pre‑Survey brief

We consult with your architect, engineer or builder to confirm project scope, required data detail and coordinate system preferences.

2 | Field Data Capture

Our crews collect topographic, structural and natural surface data using robotic total stations using a variety of equipment to get the best results. We record buildings, kerbs, services, trees, easements, drainage, driveways and contours.

3 | Data Processing & drafting

Captured data is processed in our CAD platforms to produce accurate plans aligned with the Australian Height Datum (AHD) and Map Grid of Australia (MGA) coordinates if required.

4 | Quality Review & Deliverables

All plans undergo internal QA and validation against control points before delivery. You’ll receive digital outputs in AutoCAD (DWG), and PDF.

Frequently Asked Questions

What is a detailed or topographic survey?
It’s a comprehensive mapping of all visible site features — including buildings, levels, vegetation, and services — used as the base for design and approvals.

When do I need one?
Before design, development or construction begins, especially when preparing engineering or planning drawings for submission.

How is a detailed survey different from an identification survey?
A detailed survey focuses on physical features and levels. An identification survey confirms property boundaries, ownership, and easements.

Do you provide AHD and coordinate references?
Yes. All surveys can be referenced to the Australian Height Datum (AHD) and Map Grid of Australia (MGA) coordinates.

What formats do you provide?
We supply DWG, and PDF files — ready for architects, engineers, and council use.
