Projecting towards the future: The Dinamica EGO software

Dinamica EGO [1] is free software developed for environmental analysis and landscape dynamics, which allows the creation of future trends from a self-training procedure using previous situations at different times. The platform construct models through a graphical interface in which the calculation functions (functors), the initial data (maps and tables) and the results (maps, tables and weights) are incorporated through the connectors of its ports (Figure 1). Dynamica EGO has implemented calculation engines that allow maximizing hardware resources (parallel processing, memory, ...).
 
Its main use is based on the application of various calculation functions related to changes in land cover and land use structures, as well as a part of the analysis of landscapes available to the platform. In this way, a model with great flexibility is generated using the variables that affect the change according to the territory analyzed. The resulting model, once calibrated, will allow the analysis and the proposal of a future scenario of the changes that have occurred over time in land uses or landscapes.

The results of future trends analysis also allow their application to evaluate their possible environmental incidents. Some examples of environmental analyzes using the pre-established result with Dynamica EGO are linked  to the study of different scenarios such as deforestation [2, 3], recent changes in land use and climate change [4, 5, 6] and also the evaluation of processes related to water resources {7,8,9].
