Seequent Chief Technology Officer John Vandermay participated in a mainstage panel during the Cesium Developer Conference 2025, where he demonstrated the capabilities of Seequent Evo and the application of Cesium’s 3D geospatial technology.

The conference, held in Philadelphia, connected more than 400 developers and integrators shaping the future of open geospatial technologies. Cesium is the 3D geospatial platform that powers thousands of 3D geospatial applications, including Google’s Earth engine. Cesium is part of Bentley Systems, alongside Seequent.

Initially available to mining customers, Seequent Evo was launched at the Prospectors & Developers Association of Canada conference which was attended by more than 27,000 people in Toronto in March. Evo is an open data and compute platform designed to connect and consolidate geoscience data from any source.

Vandermay addressed the audience at Loews Philadelphia Hotel, highlighting that the subsurface industry is plagued by disparate solutions and walled gardens. However, Seequent is moving towards openness and simplicity.

Seequent’s presence at the Cesium Developer Conference 2025 underscores the company’s broader commitment to openness and collaboration within the geospatial and geoscience communities.

Powering the subsurface with Cesium

A cornerstone of Evo’s innovation is its integration with CesiumJS and Cesium ION, which power geospatial search and geolocation of subsurface objects. All geoscience data in Evo is fully georeferenced, supporting a wide range of coordinate systems and enabling users to explore the underground in a rich, immersive 3D environment.

At the heart of this experience are Cesium 3D Tiles, which allow Evo to render massive, intelligently-derived subsurface structures with high performance. These models, built from sparse data using predictive algorithms, are visualised using Three.js (a JavaScript library that lets users create interactive 3D graphics in the browser using WebGL), enabling users to ‘see’ what lies beneath the surface.

Leveraging Cesium’s world-leading technology for creating powerful 3D geospatial applications, Evo customers can search & find and utilise data they didn’t know they had, enabling better informed decisions.

From exploration to insight

In mining applications, Evo’s capabilities enable users to visualise exploration drilling, analyse rock types intersected by boreholes, and transform 2D geophysics into 3D geological models. Evo’s Driver app can discover complex 3D lithological and grade relationships using a novel machine learning method, while advanced simulation and block modelling tools support mineral resource extraction.

This openness extends beyond Seequent’s own ecosystem. Evo supports data from partners, public sources, and even competitors, enabling users to discover and utilise data they did not know they had.

A commitment to open science

As Evo continues to evolve, Seequent plans deeper integrations with Cesium and Bentley technologies, reinforcing its mission to make the subsurface accessible, actionable, and open to all.
