GCS Geospatial and Hobu, Inc. announced on March 19 that they have recently concluded support for National Geospatial-Intelligence Agency (NGA) Boosting Innovative GEOINT Research Broad Agency Announcement (BIG-R BAA) Topic 10 “Advanced 3D Analytic Tool Development, Enhancement, and Integration.”
The team delivered an update to its browser-based Eptium tool that enables simultaneous co-exploitation of multiple cloud-native 3D datatypes. The team also delivered improvements to its Line-of-Sight (LOS) plugin to Applied Imagery’s Quick Terrain Modeler (QTM), alongside a novel approach to reporting viewsheds with multi-class output.
Eptium is a browser-based Electronic Light Table (ELT) that supports analytics, visualization, and light exploitation of cloud optimized point clouds (COPC), cloud optimized GeoTIFFs (COG), and the Open Geospatial Consortium (OGC) 3D Tiles. The Hobu, Inc. team expanded Eptium’s analytical capabilities and responded to beta tester feedback while improving performance throughout, especially for point cloud and raster rendering.
Using Cesium’s API, Eptium can now generate rays between an observer and target point(s), collecting information on intersections along the sight line(s). These collected points are rendered and can be exported as a Polygon File Format (PLY). The 3D Viewshed tool works with any Cesium-renderable data types, including point clouds, 3D Models, and terrain mesh.
