LuHaGeoIT project aims to contribute to a more open flow of information on climate change research to support decision making and citizens, to develop remote sensing and GIS methods (GeoIT) to serve stakeholders and policy makers in many unsolved issues on climate change (such as floods, storms, forest insect damages, farmer's information needs in changing situations) and to demonstrate the information on global change by a mobile phone-based 3D game engine, which is one of the possible future map visualization systems.
