The GEORIZON Viewer is a high-performance, web-based geospatial viewer designed for visualizing and exploring large datasets from mobile mapping systems, aerial surveys, drone imagery, and LiDAR sensors. The platform provides a vendor-independent environment where organizations can combine multiple geospatial data sources and interact with them directly in the browser. GEORIZON supports a wide range of data types commonly used in modern geospatial workflows, including panoramic street-level imagery, aerial imagery (nadir and oblique), drone imagery, LiDAR point clouds, textured 3D meshes, elevation models, and vector layers. These datasets can be viewed simultaneously within a single interface, allowing users to move seamlessly between ground-level imagery, aerial perspectives, and 3D spatial data. This integrated visualization makes it possible to analyze spatial environments with both photographic detail and accurate 3D geometry. A key characteristic of the GEORIZON Viewer is its vendor-independent architecture. The platform is designed to work with data from different mobile mapping systems, aerial survey providers, drone mapping platforms, and LiDAR sensors. This allows organizations to combine datasets from multiple vendors within a single viewer and prevents dependency on proprietary ecosystems. As a result, organizations retain full control over their geospatial data infrastructure. The viewer is optimized for large geospatial datasets, enabling efficient streaming of high-resolution imagery and dense LiDAR point clouds directly in the web browser. Users can navigate large areas smoothly without requiring specialized desktop GIS software. Built-in tools support measurements, spatial inspection, and interactive exploration of imagery and 3D data. GEORIZON integrates seamlessly with existing GIS platforms, CAD systems, and asset management software through APIs and standard geospatial services. This allows imagery, LiDAR, and 3D datasets to be connected to existing geospatial workflows and enterprise systems. The viewer can also be embedded in web applications or digital platforms to provide access to geospatial data across organizations. The platform plays an important role in digital twin environments, where large geospatial datasets represent real-world locations. By combining mobile mapping imagery, aerial imagery, drone data, LiDAR point clouds, and 3D models in a single viewer, GEORIZON provides a scalable visualization layer for organizations working with complex geospatial and digital twin datasets.
