Introducing the Global Overlay Mapper
Welcome to 'GOM v5' - the latest incarnation of the Global Overlay Mapper - a unique Windows mapping program for Radio Amateurs that combines 37 distinctive Overlay maps with new Online, World, Great Circle, and GrayLine Maps, plus a range of data-tables with plot, search, browse, and import facilities.
'GOM' can import ADIF logs, Cabrillo logs, and a variety of lists, and then georeference them from the HamQTH online database, and then plot World QSOs, Grid Locators, Countries, CQ and ITU Zones onto 37 continental and sub-continental Overlay maps, a zoomable Online Map with a choice of map-providers, a full-screen World Map, and a Great Circle Map with a choice of 16 different backgrounds and 4 different projections.
You can edit logs, check for errors, parse for countries and zones, add Grid Locators, export data in different formats, search and browse the databases, overlay a variety of lists, export the maps for use in other applications, or to share online. For further reference, see the comprehensive GOM v5 Help Guide.
