The Talwani software is a gravity profile forward modeling program based on the technique of Talwani et al. (1959) and Cady (1980).  This version of the program runs on a PC using the Windows operating system. The model that the user constructs can consist of 2-D (infinite strike extent) or 2-1/2 dimensional bodies. The term 2-1/2 dimensional means that the polygons that comprise the model do not implicitly extend to infinity in and out of the computer screen. Instead, one can look at a gravity map of the region of the profile being modeled and determine the strike length of the main anomalous bodies in and out of the screen and enter these values into the program. By making the strike extent a large number such 1000 km, the program is effectively 2-D in nature.
