Figure 1. 3D scene of San Juan Bautista, CA, built from simple latitude / longitude input and user-specified radius. Open-source data from Open Topography API and Open City Model were loaded to CoViz 4D using a script in a Jupyter notebook.
Figure 2. 3D scene of McNeil Island, WA, Corrections Center. A Jupyter notebook script was used to access open-source data from Open Topography API and Open City Model for a given radius around the input latitude / longitude.
Figure 3. CoViz 4D animation of airborne mission showing surface DEM, flightpath and buildings. The building color reflects the clearance distance from the aircraft, and coloring changes on-the-fly as the mission route is rehearsed.

DEM are from the SRTM (Shuttle Radar Topography Mission); The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near-global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000. SRTM is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA).

Open City Model is an initiative to provide cityGML data for all the buildings in the United States. By using other open datasets in conjunction with our own code and algorithms it is our goal to provide 3D geometries for every US building. https://github.com/opencitymodel/opencitymodel
