Since I was poking around looking for randomizing arcscripts this evening, too, I thought this might do the trick, for your transects. (Maybe more so for someone searching the list archives in the future, as it appears to do more, and maybe less, than the script that's already been posted. Probably handy for *designing* a sampling transect, rather than recreating one.) http://arcscripts.esri.com/details.asp?dbid=12538 From the description: The Point Dispersion Wizard disperses coincident points radially, linearly, randomly within a specified radius and randomly within a containing polygon. In addition, each dispersion pattern comes with a set of user specified options. Dispersed points can be displayed as graphics in the existing theme, clipped to a new theme, or dispersed in a new theme. It was written for ArcView 3.1 using the Dialog Designer. Be sure to study the included READ_ME.txt file as it explains the usage of the Point Dispersion Wizard, especially as it pertains to the randomly within a containing polygon dispersion pattern which behaves somewhat differently than the other dispersion patterns. The random dispersion pattern options use a prime modulus multiplicative linear congruential generator to generate random variates from the uniform distribution on the interval [0,1] based on Marse and Roberts (1983).
