1. An information processing apparatus comprising
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
receive, from a mobile mapping system (MMS) measurement data including three-dimensional point group data including a columnar structure and raw image data;
convert the raw image data into Joint Photographic Experts Group (GPEG) data that is irreversibly compressed;
read two-dimensional data regarding a local region from a two-dimensional facility database;
from the three-dimensional point group data, creates a solid model of the columnar structure and a solid model of an attachment attached to the columnar structure;
determine a positional relationship between the columnar structure and the attachment from the solid models; and
determine an owner of the attachment from the positional relationship.
