Must be Latin week on this site; following yesterday’s post on the latest release of the Spanish GIS gvSIG, the Brazilian geospatial modeling program Dinamica EGO (Environment for Geoprocessing Objects) sent me an email announcing release of version 1.6. Wasn’t previously aware of the program; from the website:
Dinamica EGO consists of a sophisticated platform for environmental modeling with outstanding possibilities for the design from the very simple static spatial model to very complex dynamic ones, which can ultimately involve nested iterations, multi-transitions, dynamic feedbacks, multi-region and multi-scale approach, decision processes for bifurcating and joining execution pipelines, and a series of complex spatial algorithms for the analysis and simulation of space-time phenomena.
The software environment, written in C++ and Java, holds a series of algorithms called functors. Each functor performs an operation. We have implemented the most common spatial analysis algorithms available in commercial GIS (Geographic Information System), plus a series of algorithms especially designed for spatial simulations, including transition functions and calibration and validation methods. Dinamica EGO functors are sequenced in a graph form to establish a visual data flow. With the help of its graphical interface, one can create models by simply dragging and connecting functors via their ports, each of which represents a connector to a data element, such as a map, a table, a matrix, a mathematical expression, or a constant. Thus, models can be designed as a diagram, whose execution follows a data flow chain. This friendly interface allows for creative design of spatial models that are saved in XML format or EGO programming script language. In sum, Dinamica-EGO favors simplicity, flexibility, and performance, optimizing speed and computer resources, such as memory and parallel processing.
I’m not even going to pretend that I understand its full utility, but hopefully some of you do and might find this useful. List of new features (and those added in earlier version releases) available here. Free download for educational and scientific purposes only; registration required
