ABSTRACT

The stratigraphic model editor provides a convenient and efficient tool for geophysicists manipulating the complex models used in ray tracing and other forward modeling techniques. The editor allows the user to build a model of the earth on a Symbolics Lisp Machine screen using the mouse. The earth models manipulated by the program represent a two-dimensional slice of the earth, typically extending three or four miles down and having 10 to 50 layers. The layers need not be flat, but can contain features such as reefs and salt domes. These models are important in exploration geophysics. The editor generates data files representing this model that can be used as input to a ray-tracing program. The description of the file format is written in a high-level declarative language, so that the editor can be easily modified to support other formats.
