Geoinformatics for Environment and Energy represents a domain centered on the creation and/or application of data, mathematical models, and computational resources to provide the requirements to study the environment and energy as components of earth system. Assuming that Environment and Energy is a connected network, Geoinformatics plays a pivotal role in the multidisciplinary approach to understanding and addressing the complexities of this network. The relationship between different aspects of environment and energy is complex with multiple layers of interdependence. Addressing the challenges within this complex network requires approaches that involves large data sets and models, considering not only the technical aspects of energy production but also the broader social dimensions. The use of data, algorithms, mathematical models, and computational power is instrumental in making sense of the complex interconnections within the energy and environment network. Here is an example of how Energy and Atmosphere (as a part of Environment) are related.
