Hello, Found this great site today that has nice geological maps for many Eastern European countries, plus some more. http://www.geokniga.org/maps Some maps are outdated in terms of roads, but the geology remains more or less the same. Zoom in and out using +,- on your left. If someone not familiar is interested in those areas, use this site to convert Cyrillic to latin, then translate. https://www.lexilogos.com/keyboard/russian.htm The legends on the maps though are international and recognized by colour.
Background I've been amassing a collection of old geological maps showing various areas of interest around Washington, but I've been disappointed that most of them are not georeferenced (i.e. they can't be used in a mapping app and show your current location on the map). While this is only a minor inconvenience, since I can toggle between a topo map and the geological map, I've been searching for a way to add georeferencing to existing maps. And I've found it!* Software needed: QGIS (free & open source): https://www.qgis.org/en/site/forusers/download.html
