Linfo – a visual basic program for lineament density, frequency and intersection density analysis

Abstract

This paper describes the development of visual basic program called ‘Linfo’ which can be used for calculation of spatial properties (orientation, length, density, frequency and intersection density) of lineaments. The program allows the user to analyze the orientation of lineaments easily and shows the results in the form of rose diagram. Linfo can handle large number of lineaments at a time and calculates the results faster than any other software. Linfo generates regular square grids over lineament data and calculates the number, length and intersections of lineaments that fall within each cell. The program is validated with lineament data of Kerala state, India and prepared the spatial maps using Inverse Distance Weighted (IDW) interpolation method. The experimental results show that Linfo is useful for generating spatial maps using any interpolation method. Potential application of the program includes demarcation of groundwater potential zones, landslide risk assessment etc.
