Spatial analysis is an increasing growing science in the fields like landscape ecology and genetics, however, statical evidence is not easily accessible. PASSaGE 2 (Pattern Analysis, Spatial Statistics and Geographic Exegesis) is on the up and up. Surpassing its original PASSaGE, PASSaGE 2 is now more user friendly, supports both scientific analysis and classroom training, and includes a more broad array of spatial statistical analyses. But what is Spatial Analysis; its a "fundamental part of scientific inquiry including ecological, evolutionary, and environmental science, epidemiology, geology, geography and mathematics". Now, with PASSaGE 2 being a newer, easier to use, rebuilt version of the original PASSaGE there are far more downloads of it, 12,000 in over 76 countries to ball park it. With this program. there can be a stronger graphical support with a variety of mapping and graphic functions.
