T-PROGS offers a transition probability-based geostatistical approach to stochastic conditional simulation of spatial distributions of categorical variables. T-PROGS can be used to analyze spatial variability and generate realizations of geologic units or facies. Importantly, the realizations attempt to honor existing data and display consistency with the spatial variability evident in data or other geologic observations. (CARLE, 1999)

A. Watch the videos below for some examples of transition probability-based geological modeling using borehole lithologic data from water well records. 

B. Then use MAGNET to develop a TP-based geological model for the following areas, taking advantage of the rapidly growing global water well database built-in within MAGNET. (Note: the expanding MAGNET water well database currently only covers part of the world: Michigan, Oregon, California, Indiana, Ireland, … .)
