Mobile Laser Scanning
Detailed 3D mapping of roads, corridors and surrounding assets. Read about Mobile Laser Scanning.
Surveying • Scanning • Subsurface Mapping
Surveyors in Australia
Making the invisible, visible.
Understand your site above and below ground. Clear, accurate survey and mapping information to help you plan, design and build with confidence.
Established 2018 • Eight specialist capabilities • One experienced team
Reality capture with subsurface intelligence.
UDM combines mobile laser scanning, surveying and subsurface investigations to reveal existing site conditions—from roads, buildings and terrain to underground services and concealed structures.
We turn complex site information into practical plans, detailed 3D models and spatial data for infrastructure, construction, property development and asset management. Each project brings together the methods needed to answer your questions and support your next decision.

About UDM
We’ve operated since 2018, building UDM into a multi-disciplinary team of 15 people. Our surveyors measure sites above ground and investigate what sits beneath them, using ground penetrating radar in single, multi-array and mobile forms, CCTV pipe inspection inside pipes and drains, concrete scanning before cutting or coring, and reality capture and UAV LiDAR where a site needs recording in three dimensions. Our Director, Rod, has worked across the industry and regularly guest-speaks at commercial construction and utility compliance conventions. That technical perspective shapes how we approach project scoping, fieldwork and the information we deliver. We work with homeowners, builders, construction companies and property developers, while our growing capability also supports civil, infrastructure, corporate and government project requirements.
About UDM
Locations We Service
UDM supports surveying, subsurface investigation and spatial-data projects across a growing Australian operational footprint. Our location pages outline the areas we service while our project approach remains driven by scope, access, site conditions and the information required. Whether a project calls for ground penetrating radar over the ground, CCTV pipe inspection inside a line, concrete scanning ahead of cutting, or surveying and spatial work, reality capture and UAV LiDAR above the surface, we can talk through the combination of methods that suits it.
