Collection Geometry for Building Voxel Models

Even though just about any collection with cameras can build a voxel world, certain collection geometries are more ideal for the voxel world calculations, and result in good models. Good collection geometries capture multiple view angles of all the surfaces to build up the 3D voxel world.

When planning a collection, one of the first decisions to make is “What size voxel will be generated?” The voxel size determines the smallest possible voxel surface size, after refining (smallest blue box in the figure below). The voxel size should match the nominal GSD during collection, where
