ABSTRACT:
This Earth Photo Globe is characterized in that LANDSAT or other remote sensing geographical indicia is reproduced on the globe sphere with a definition smaller than that resolvable by the unaided human eye. An optical magnifier is mounted above the globe sphere to enable resolution of the full globe definition. A "cloud cover" spherical overlay may surround the sphere and contain a representation of the earth's cloud cover. The magnifier may be supported by this overlay.
Various systems are disclosed for making the Earth Photo Globe. One uses a laser beam that is raster scanned across a photosensitized sphere, and is modulated by LANDSAT pixel data. In another system the LANDSAT data is used to prepare a set of photographic negative images each covering a section of the globe, and each containing alignment and positioning information. These images are projected onto a photosensitized sphere to make the globe.
Several globe-illumination systems are also disclosed, including a diurnal interior lighting assembly and a surface lighting scheme for displaying geopolitical data.
