The document discusses photogrammetry workflows for capturing exterior and interior architectural spaces. It covers topics such as photogrammetry basics, data capture including vehicle payloads and mission planning, data processing software options, and output formats including point clouds, 3D meshes, and methods for integrating the data into BIM platforms. Sample projects demonstrate the process and potential applications like clash detection and virtual tours are presented.
