As a part of the preparation for FOSS4G NA conference, we created a case study of the St. Louis Downtown, showcasing much of our technology stack. Geomni provided us with oblique aerial imagery. Our Vadstena Photogrammetry pipeline was used to create the 3D textured model and we used some our more recent R&D to extract the LOD2 model of a few city blocks.
We used the open-source VTS 3D Geospatial Software Stack to perform fusion of the textured 3D model with a global DEM and a global orthophoto mosaic to facilitate seamless rendering. City of St. Louis provided us with parcel data for the area.
