The tomographic apparatus of this invention has an attenuation quantity calculating and adjusting unit, a filter length calculating unit, an attenuation correction function calculating unit and a transmission length calculating unit in an arithmetic processing unit. A plurality of motherboard connection terminals are disposed to correspond to the openings. Geo-coded images can be displayed on a map and browsed or queried based on their location metadata. Further, a fourth step of transmitting data to the corresponding process if there is the same address data set in the network MAP of the attached resource computer network in the previous third step is performed.
