Spatial analysis of lineaments

Abstract This paper describes a program that will perform some simple spatial analysis of lineaments, and which is useful particularly for lineaments that are arranged as parallel sets. The lineaments may be geological faults, drumlins, linear sand dunes, or any other phenomena that can be mapped as single line-elements. The outputs from the program are lineament lengths, orientations, parallel and perpendicular spacings, nearest-neighbor distances, and an assessment of how the spatial distribution of the lineaments compares to a purely random pattern. The technique was developed to support research on subglacially produced lineaments (drumlins, mega-lineations, etc.) which requires large amounts of quantitative information to be acquired to test a number of hypotheses. The programs are written in “C” and designed for use on UNIX platforms. They accept inputs of simple ASCII files that define the endpoint coordinates of each lineament.
