Cesium is 3D Geospatial Mapping & Analysis
Use Cesium ion's simple workflow to tile and host geospatial data.
Use the open-source CesiumJS library to create custom 3D geospatial mapping apps.
Fuse heterogeneous 3D data
Whether you have photogrammetry models, CAD/BIM exterior and interiors, point clouds, terrain, imagery, vector data, or all of the above, ion will tile your geospatial data into a single, interactive 3D map.
View massive datasets
Adaptive level of detail allows you to both see the big picture and zoom in on the smallest detail, from every satellite in space to every building in Manhattan.
Style and query
Use your data's attributes to style models and explore your world.
Measure and annotate
Measure distance and area and add annotations to your 3D maps.
Perform analysis
Perform 3D geospatial analysis with Cesium's 3D analytics, which allows you to evaluate the context of any point in your 3D map.
