Abstract
In previous columns under this heading I have covered some fundamental attributes of the Internet and how to use it for obtaining information of interest to seismologists. In this issue we leave the Internet for a while to take a look at a new computer program I have found quite exciting. Jonathan Lees of Yale University has been developing a GIS type of interactive display program for geological and geophysical data, which seems to fall into a niche between conventional 2-D commercial GIS programs and expensive, general purpose, 3-D display and rendering systems.

Similar to the mapping program GMT or the waveform display program SAC, Xmap8 is being actively distributed to the seismological community and feedback from users has been incorporated into it. While it is far from a commercial “shrink-wrapped” product and still has some rough...
