Mobile GIS allows users who work in the field to acquire, edit, update, store, display and analyse data. It combines modern technologies such as mobile devices (tablet, smartphone), software (applications in Android and iOS), location of a point / place using GNSS transmitter and providing wireless connectivity via the internet. An important step in any scientific research should be the verification of the obtained results, which can be done by using a modern tool such as mobile GIS. In this article the characteristics of mobile GIS will be presented as well as selected examples of modern research carried out at universities in Germany: Technische Hochschule Georg Agricola University (THGA), Technical University Bergakademie Freiberg (TUBAF) and Poland – Wrocław University of Science and Technology (WUST).
