In 1959 Talwani and others published an algorithm to compute the gravitational field of an arbitrarily shaped two-dimensional body (finite cross section and infinite horizontal extent). A Fortran program GRAV2D presented in this report follows the line-integral method developed by Talwani and his coauthors. Input may consist of one or more bodies; output may be computed at any elevation and distance. Two test cases demonstrate the reliability of the program.
