AB: Geographical Informational Systems (GIS) provide a variety of possibilities to visualize geophysical databases. ESRI ArcView 3.x software is a very useful GIS tool for palaeomagnetists. The dBASE table format make the process of transition of the database into visual form very quick and easy. The object-oriented programming language Avenue dramatically reduces time for creating user-friendly utilities and applications. Recently we transferred the Global Palaeomagnetic Database into GIS form (Pisarevsky and McElhinny, 2004), now I want to present the next achievement - visual Geomagnetic Secular Variation databases, visual Polarity Transitions database, and visual Magnetostratigraphy database. These databases contain exactly the same information, as the corresponding IAGA databases, but provide a much more friendly interfaces and a wide range of utilities. This strongly simplifies the process of searching, analysis, synthesis, and presentation of data. Additionally there are several additional possibilities, such as geographical search, quick selection of data subsets, quick calculations, graphics and others, that were impossible in previous formats of these databases. All utilities are combined into menu items, buttons and tools. They also include printing reports and storing subsets of data in formats for other popular software, including Microsoft Excel, Microsoft Word and some others. This approach also provides a lot of possibilities to combine the palaeomagnetic data with geochronolgical, geochemical, petrological, and other geographically oriented databases and with digital maps.
