The use of geographic information systems in the field is often referred to as mobile GIS. This method makes it possible to collect, edit data with a smartphone application using GNSS locations. Especially important in scientific research is the verification of the obtained results. Mobile GIS allows the integration and implementation of data from various in-situ measurements such as soil sensors or thermometer. In this paper we will present results of mobile GIS application in projects: C2M2 - Climate Change | Management and Monitoring, Digital Twin- Integrated Geomonitoring and KaMonSyS - System for monitoring the installation and safety to cavernous storage facilities using satellite and drone-derived data, carried out by Research Center of Post-Mining at Technische Hoschschule Georg Agricola.
