Better Ground Data. Less Time on Site. More Confident Decisions.
Traditional ground survey methods — traversing paddocks, tree lines, and rough terrain with total stations and GPS — are time-consuming, physically demanding, and expensive. For large areas or complex sites, the timeframe alone can delay planning and design decisions by weeks.
LiDAR-equipped drones change the equation entirely. Our aerial systems capture millions of precise elevation measurements per second, penetrating crop canopies and tree cover to reach the actual ground surface. The result is a dense, accurate point cloud that can be processed into a true Digital Terrain Model (DTM), contour map, or drainage analysis — delivered in days, not weeks.
For civil engineers, developers, councils, and landowners across Victoria, this means faster feasibility assessments, more reliable design inputs, and better decisions — at a lower total project cost.

From Site Brief to Delivered Data — Here’s How It Works
Project Consultation
Tell us about your site, your project requirements, and how you intend to use the data. We’ll advise on the most appropriate combination of aerial LiDAR, ground scanning, and GPS survey methods — and provide a clear, transparent quote. If your site requires flight approvals or airspace coordination, we handle that too.
Aerial & Ground Data Capture
Our REOC-certified pilots and surveyors mobilise to site. Our DJI M400 drone with L3 LiDAR payload captures dense aerial point cloud data, while ground control points (GCPs) — established in MGA coordinates or localised to your project — ensure survey-grade accuracy. Where terrain, vegetation, or site constraints require it, our ground LiDAR scanners and Robotic Total Station fill any gaps in the aerial data.
Processing, Drafting & Delivery
Raw point cloud data is processed into your required outputs — DTM, contour maps, drainage analysis, GIS layers, or engineering drawings. All elevations are delivered on the Australian Height Datum (AHD). Your data is provided in the format your team needs (DWG, DXF, 12D, LAZ, GeoTiff, PDF, and more), and is also available via our cloud-based viewing platform for easy stakeholder access and 3D visualisation.

Professional And LiDAR surveys delivered with survey-grade accuracy, industry compliance, and flexible data delivery options.
Our LiDAR Equipment
Storm Spatial’s primary aerial LiDAR platform is the DJI M400 drone equipped with the L3 LiDAR payload — a professional-grade system capable of capturing high-density point cloud data with canopy penetration, multi-return processing, and the precision required for survey-grade terrain modelling.
For ground-based detail, our team deploys handheld LiDAR scanners and Robotic Total Stations to fill areas the drone cannot cover and to provide critical ground-truth verification.

Operating under our REOC (Remotely Piloted Aircraft Operator’s Certificate) certification, we can plan and execute flights in complex environments — including EVLOS (Extended Visual Line of Sight) operations for large survey areas, near aerodromes, agricultural corridors, and night operations where required — in full compliance with CASA regulations.
Compliance & Quality Standards
Storm Spatial’s LiDAR survey work is delivered in compliance with the applicable Australian and international standards:
- ICSM LiDAR Guidelines v2.0 — the Intergovernmental Committee on Surveying and Mapping standard governing point density, accuracy classification, and data product specifications for LiDAR surveys in Australia
- ASPRS Positional Accuracy Standards for Digital Geospatial Data (2023 or later) — the internationally recognised benchmark for horizontal and vertical positional accuracy of geospatial products
- Surveying and Mapping Infrastructure Regulation 2014 (Vic) — or the relevant State equivalent for projects in other jurisdictions
For projects requiring formal quality assurance documentation, we provide a QA/QC report confirming compliance, completeness, and classification accuracy of the delivered point cloud and derived products. This is standard practice for government, council, and infrastructure contracts.
Output Formats
We deliver your survey data in the format your team already works with. Standard outputs include GIS layers, 2D and 3D DWG/DXF, 12D models, Pix4D project files, LAZ/LAS point clouds, GeoTiff rasters, and PDF drawings and reports. If your workflow requires a specific format, ask us.
Cloud-Based Data Access
All clients receive access to our user-friendly cloud platform for viewing, downloading, and sharing project data in 3D. No specialist software required. We provide a walkthrough session to ensure your team can navigate and extract value from your survey data independently — because data you can’t use confidently isn’t delivering its full value.
A Note on Long Grass and Dense Vegetation
Honest Advice on LiDAR in Long Grass — What You Need to Know
LiDAR is exceptional technology — but we believe in being upfront about where its limitations can affect your results. Dense or long grass is a genuine challenge for any airborne LiDAR system, including our DJI M400 with L3 payload. Even with multi-return processing, long grass can partially obstruct ground returns, introducing variability in the bare-earth classification and affecting the precision of volume calculations and fine contour work.
We encounter this regularly on agricultural sites, undeveloped land, and rural properties across Victoria — and we’d rather discuss it honestly at the quoting stage than have it appear as a surprise in the data.
How We Address It
Option 1 — Mow Before We Fly
Our standard recommendation for sites with dense or long grass is simple: mow or slash the area before the flight. Even a single slasher pass removes the primary obstruction and significantly improves ground return quality. Where timing allows, this is the most cost-effective path to the best results.
Option 2 — Cross-Pattern Passes
Where mowing is impractical, our team can fly cross-pattern passes — covering the survey grid in two perpendicular directions — to maximise the probability of ground-hit returns beneath the canopy. This improves the bare-earth classification without requiring any site preparation.
Our Commitment at the Quoting Stage
We assess standard deviation from ground returns to true ground at the quoting stage and clearly communicate any expected impact on volume calculation accuracy before you commit. If the vegetation conditions at your site would compromise the accuracy requirements of your project, we’ll tell you — and recommend the best path forward. No surprises in the data.

Frequently Asked Questions
What is LiDAR drone surveying?
LiDAR (Light Detection and Ranging) drone surveying uses a laser scanning sensor mounted to an unmanned aerial vehicle (UAV) to measure the precise distance between the aircraft and the ground surface. The sensor fires millions of laser pulses per second and records the time each pulse takes to return, generating a dense 3D point cloud of the terrain. Unlike photography-based photogrammetry, LiDAR can penetrate vegetation canopies to reach the actual ground surface — making it uniquely effective for agricultural, forested, and complex terrain sites.
What is the difference between a DTM and a DSM?
A Digital Terrain Model (DTM) represents the bare-earth ground surface — with all vegetation, buildings, and above-ground objects removed from the data. A Digital Surface Model (DSM) represents everything the laser hits first, including tree canopies, rooftops, and structures. For civil engineering, drainage analysis, and land development, a DTM is typically required because it reflects the actual ground you’ll be building on or managing water across. Storm Spatial delivers both, depending on your project requirements.
How accurate is drone LiDAR surveying?
Drone LiDAR surveying with properly established ground control points (GCPs) can achieve horizontal and vertical accuracies in the range of 20–50mm under survey-grade conditions. Actual accuracy depends on flight parameters, GCP quality and distribution, terrain conditions, and the specific LiDAR system used. Storm Spatial’s DJI M400 with L3 payload, combined with GPS and Robotic Total Station ground control, delivers results referenced to MGA coordinates and the Australian Height Datum (AHD) — meeting the requirements of ICSM LiDAR Guidelines v2.0 and ASPRS Positional Accuracy Standards.
Can LiDAR penetrate tree canopies and crops?
Yes — this is one of the key advantages of LiDAR over photogrammetry. LiDAR systems emit multiple pulse returns per shot, meaning some pulses pass through gaps in the canopy and return a ground hit. This allows Storm Spatial to generate accurate bare-earth DTMs even on heavily vegetated or cropped sites. For particularly dense canopies, ground-based LiDAR scanning or GPS survey can supplement aerial data in critical areas. Note that long or dense grass presents specific challenges — see the Long Grass Advisory section above for our honest assessment and recommended approach.
Does long grass affect LiDAR accuracy?
Yes, and we think it’s important to be upfront about this. Dense or long grass is a genuine challenge for airborne LiDAR, including our DJI M400 and L3 system. Long grass can absorb or deflect laser returns before they reach the true ground surface, reducing the density of accurate ground-hit points and introducing variability into bare-earth classification. The practical effect is that volume calculations and precise contours in heavily grassed areas may carry a higher standard deviation than those on clear or mown ground. Our standard recommendation is to mow or slash the area before the flight where possible. Where that’s not practical, we can fly cross-pattern passes to maximise ground returns. We discuss site conditions and expected accuracy implications at the quoting stage — no surprises in the data.
What is REOC certification and why does it matter?
REOC (Remotely Piloted Aircraft Operator’s Certificate) is the highest level of drone operator certification available in Australia, issued by CASA (Civil Aviation Safety Authority). It allows Storm Spatial to operate in complex and restricted environments — including controlled airspace, near aerodromes, over populated areas, and at night — where uncertified operators cannot legally fly. For government, council, and infrastructure projects in particular, working with a REOC-certified operator ensures legal compliance and eliminates project risk from regulatory non-compliance.
What compliance standards do you work to?
Storm Spatial’s LiDAR survey work is delivered in compliance with ICSM LiDAR Guidelines v2.0 (the Australian national standard for LiDAR data collection and classification), ASPRS Positional Accuracy Standards for Digital Geospatial Data (2023 or later), and the Surveying and Mapping Infrastructure Regulation 2014 (Vic) or relevant State equivalent. For projects requiring formal quality assurance, we provide a QA/QC report confirming compliance, completeness, and classification accuracy of the delivered point cloud and derived products.
