3D World

Airbus 3D World includes a range of Digital Elevation Models (DEM) including DEM 5, DEM 1, and DEM 0.5. Each is available as a Digital Surface Model (DSM) or Digital Terrain Model (DTM).

DEM 5 (formerly WorldDEM Neo) is the global, off-the-shelf elevation dataset built from Airbus’ TanDEM-X and TerraSAR-X radar missions, with coverage recomputed from 2021–2025 data. DEM 1 and DEM 0.5 (formerly Elevation 1 and Elevation 0.5) are produced on demand, so customers get fresh data acquisitions over their area of interest. DEM 0.5 is based on Pléiades Neo 30 cm imagery and delivers photorealistic 3D quality, capturing trees, buildings, and infrastructure with industry-leading detail.

From global reference layers to high-resolution, tasked elevation data, Airbus 3D World provides a consistent and scalable foundation for mineral exploration, infrastructure planning, line-of-sight analysis, hydrological modelling, and defence operations.

"Our gold exploration project needed some special attention being located on a weather beaten island with lots of cloud, snow, fog and other items to consider. Pacific Geomatics understood this and provided a competent service and modern support tailored to our needs resulting in satellite images we could use quickly and effectively. Products were tasked with a constant view to weather windows and always delivered on time. New Found Gold would highly recommend Pacific Geomatics for mineral exploration needs and the wide range of products they provide."

New Found Gold Corp. - Senior Project Manager

"PacGeo makes locating and purchasing satellite imagery easy. Their online search tool and ordering process is intuitive and the end product is excellent quality. We have used them for multiple years to order high resolution imagery for disturbance mapping at a fraction of the cost of airborne surveys. We would recommend them to other exploration companies as it is the easiest and fastest way to get high resolution imagery for your project."

Graeme Joyce

Klondike Gold Corp. - GIS Manager

"I am delighted to recommend PacGeo as an outstanding satellite imagery provider. Their extensive product knowledge has proven invaluable to our projects. What sets PacGeo apart is their commitment to providing excellent advice, always offering insightful and practical suggestions. Their customer service is unparalleled in the market – communication is seamless, responses are prompt. I confidently endorse PacGeo to any professional or organization seeking reliable products, expert advice, and great customer service."

Harfang Exploration - VP Exploration

"The service provided by PacGeo was great. From the first time I contacted them to request quotes, through the purchasing and delivery of data, they were always responsive and helpful. One of the things that I liked the most was that they did not try to push any particular type of data, but rather worked with me to determine what was best for my needs, even when it meant going to providers to get solutions that were not off-the-shelf. Even after the data was delivered and we had technical issues with storage on our end, John made sure it was redelivered so our project could move forward. I would work with them again without hesitation."
