A hybrid database can receive a hybrid query for an object having a real world analog. A feature of a set of feature records can be determined that corresponds to the object. Feature-level attribute values of the feature can be extracted from the feature records. A set of uniquely indexed voxels can be determined. Each voxel can be a volumetric unit of the volumetric storage space that represents the volume of real-world geography. Voxel-level semantic values can be extracted from the set of uniquely indexed voxels from voxel records. Extracted voxel-level semantic values and extracted feature-level attribute values can be combined to generate a hybrid result. The hybrid result can be conveyed to a requestor from which the hybrid query was received.
