Software and the Web

New Web Tool
In 1998, the DMC moved to an Oracle database to keep track of data - both meta and waveform. SeismiQuery was created so users could interface with the database via the web and without having to learn SQL. SeismiQuery is made up of several "pre-written" queries that allow users to set parameters for database searches and to select output options (screen view and/or email). We have recently added to the station, channel and event queries a "Make Map" option - a GMT-based mapping utility. Options set by the user include zoom, lat-lon box, map title, large or small view, cities, fault lines, color or black and white maps, gif or postscript file, etc.. Try making a map of your own by running a station, channel or event query in SeismiQuery.
