How to Add Shapefiles (as GeoJSON) in CesiumJS and Control Their Visibility & Opacity

Cesium / October 17, 2025

Introduction CesiumJS is a powerful open-source 3D globe and map engine that allows developers to visualize geospatial data in real-time. However, since Cesium doesn’t directly support shapefiles (.shp), we typically convert them to the more web-friendly GeoJSON format. In this tutorial, we’ll see how to: This is particularly useful when building GIS visualization tools, map […]

Visualizing a Radar Scanning Sector in CesiumJS

Cesium, Simulation / September 14, 2025

In many defense and simulation applications, it’s useful to display the field of view (FOV) of a radar system mounted on an aircraft or ship. Using CesiumJS, we can dynamically render a radar sector that updates with the platform’s position and heading. In this post, we’ll walk through how to: 1. Adding the Ownship Entity

How to Display a Raster Image at a Specific Location in CesiumJS

Cesium, Simulation / September 12, 2025

Introduction CesiumJS is a powerful open-source library for creating 3D geospatial applications on the web. While it is widely used for visualizing vector data, 3D tiles, and terrain, raster imagery also plays a crucial role in many applications. Raster images such as satellite snapshots, scanned maps, or custom overlays can provide valuable context to your
