Our strongest recommendation goes to Marble, a lightweight, fast, educational geographical virtual globe and world atlas.
It offers a classic topographic map, a global roadmap created by the OpenStreetMap, and a satellite view (shown in the image). The software offers other views: Behalm Globe 1492, Earth at Night, Historical Map 1689, Plain Map, Political Map, 2 Precipitation views, 2 Temperature views, and Vector OSM (a global roadmap). There’s also a satellite map based on ESA’s Sentinel 2. Marble is supplied with a database of more than 12,000 locations (cities, mountains, volcanoes) which can be searched for and which are integrated with Wikipedia. WorldWind is an open source (released under the NOSA license) virtual globe initially developed by NASA’s Learning Technologies project. This Java software offers a geographic context with high-resolution terrain, for visualizing geographic or geo-located information in 3D and 2D. Some of the functionality provided by Google Earth Pro is covered by other types of open source software. OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere on Earth. It’s kept up to date by people using GPS devices, aerial photography and other free sources of information. There are various open source software that taps into and other similar services. Our favorite is QGIS, an Open Source Geographic Information System (GIS). In QGIS version 3, there are built-in features to use raster and vector data from OpenStreetMap. The OSM plugin, a core QGIS plugin, provides the basic functionalities for OSM data manipulation this includes data loading, importing, saving, downloading, editing and uploading data back to the OSM server.
