Preliminary Investigations of the Geographic Applications of Holography: Final ReportThis report provides an introduction to optical holography and its applications in Geography. The nature of the holographic process is explained and its advantages and disadvantages are considered. The forms and formats of spatial data are examined in respect to the requirements for a holographic data storage systems. Digital-optical interfaces allow the creation of hybrid computing devices and three applications of these to spatial analysis and data display are indicated. The relationship of holographic theory to associative data structures also is considered. (Author). |
