Construction of lineament maps related to groundwater occurrence with ArcView and Avenue scripts ?
A set of lineament maps has been constructed, comprising a lineament distribution map, a lineament length density map, a lineament counts density map and a lineament cross-point density map. The ArcView SHP file is used as input format. Two Avenue script files (Remove-node and Generalize) have been developed, in which input errors can be minimized, to optimize the original digitized lineament map data. For analyzing the lineament characteristics, five Avenue script files (L-STAT, Dist-to-Line, Dist-to-Cross-point, L-Selection and PL-DENS) calculating the lineament statistics (lineament length density, counts density, cross-point density, distance between a well and the nearest lineament, and distance between a well and the nearest lineament cross-point) have been developed with Avenue language using ArcView 3.1 GIS software. It is very easy to calculate the lineament-related values with the above five script files. They are also useful for drawing lineament density maps and for revising and compiling existing lineament density maps with ArcView 3.1 GIS software. Lineament alignment or lineament density distribution can play an important role in groundwater exploration or productivity analysis. These script files, together with well data, can facilitate analysis of the relationship between groundwater characteristics and lineament distribution.
