Abstract
The first phase of development of intervisibility software for use in experiments on human factors in command and control is described, and the importance of intervisibility in military situations is noted. The theoretical aspects of intervisibility in relation to digital terrain models are discussed. A list is given of spatial operators, including intervisibility operators, which might be integrated into a spatial database management system, and methods are suggested for carrying out that integration. Special types of intervisibility operator, including a depth-below-line-of-sight operator and a skyline operator, are discussed in detail. Notes are included on fractal spatial entities and on fractal spatial operators that might be developed. Some discussion of spatial data types is given, relating them to the spatial operators that make use of them.
