Features

From raw data to interactive 3D on every platform

Horizon covers the full rendering stack (terrain, vectors, 3D models, interactivity) in a single engine optimized for geospatial data.

Terrain & raster streaming

Terrain & raster streaming

Stream tens of imagery or DTM layers simultaneously, from global to centimeter resolution. Colorize data rasters on the fly with a palette.

Vector & 3D model rendering

Vector & 3D model rendering

Six vector representations (extruded polygons, cylinders, heatmaps, instanced models, symbols, flat overlays) plus glTF and 3D Tiles, from object to city scale.

Scriptable styling

Scriptable styling

A built-in scripting language lets you filter, compute, and style every object from its attributes. No preprocessing, style logic runs live in the engine.

Interactive tools

Interactive tools

Multi-view rendering, picking & highlighting, viewshed analysis, shape editor, and clipping planes, all built-in, ready to wire into your application.

Platform

Native performance, everywhere you deploy

Built on native technologies and WebAssembly, Horizon runs on Windows and Linux via OpenGL 3, and in any modern browser via WebGL 2. C++ and TypeScript APIs are available, and the Protocol Buffers-defined interface makes Horizon usable from any language.

  • Web (WebGL 2)
  • Windows & Linux (OpenGL 3)
  • C++ & TypeScript APIs

Use Cases

From digital twins to web maps

Horizon adapts to projects of any scale: city-wide infrastructure, field analysis tools, simulation dashboards, or embedded web maps.

Urban digital twin

Navigate city-scale 3D Tiles with LODs, dynamic material overlays, and live data feeds.

Simulation visualization

Overlay colorized raster results on terrain, display 3D heatmaps, and animate flow data to communicate simulation outputs clearly.

GIS & field analysis

Viewshed analysis, shape editing, picking and measurement. Professional GIS tools embedded directly in the 3D view.

Web mapping integration

Embed a 3D map into any webpage with a transparent background, scriptable styles, and full rendering control.
