These script files, together with well data, can facilitate analysis of the relationship between groundwater characteristics and lineament distribution. Equation of the line connecting the two circles centers: y 1.5x + 3.5. termediate Contours (MIC) algorithm computes new, in between contours in much the same way. The Maximum In-Figure 1: A portion of contour map. Lineament alignment or lineament density distribution can play an important role in groundwater exploration or productivity analysis. The circles intersects at the points: (3.86, 2.91) and ( 0.94, 0.29) Equation of the line connecting intersection points: y 0.66x + 0.33. This is done by drawing a new contour midway between successive contours. They are also useful for drawing lineament density maps and for revising and compiling existing lineament density maps with ArcView 3.1 GIS software. It is very easy to calculate the lineament-related values with the above five script files. Were currently using MapInfo & MapBasic to analyze daily tests results for planning purposes. 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. endpoints (circle in dashed line in Figure 1b) that does not contain either of its associated Voronoi vertices (V 1 and V 2 in Figure 1b). 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.
Besides the writing of the header, an ordinary script must.
The ArcView SHP file is used as input format. Copy the header information and use the PRINT command to write the contents to the MapInfo MIF file. 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.
