   I'm not a geologist so I don't know how best to extrapolate from well
logs. I've used water well logs to determine the presence of impervious
layers and aquifer surfaces, but not tried to imcorporate those data into a
GRASS analysis. But your comment above makes me wonder if calculating
Veronoi diagram of these various layers would provide that majority vote.
