This deliverable contains, as a hyperlinked on-line Multimedia document, some initial material describing the philosphy, approach, and specific implementation within ther MUTATE project, of the interactive dynamic modeling components. Its objective is to introduce the philosophy and approach, as well as a number of concrete examples of functionality and interface style to facilitate the discussions between tool developers and content developers within the MUTATE project team.
describes an initial set of models to be integrated, and provides on-line references to detailed model documentation;
it offers a first description of the model architecture and client-server communication protocols and options that implement this philosophy;
and it provides a few first demonstration prototype examples of Java-based and fullt Internet accessible servers (a GIS model server and an air quality model, using the Geneva case study) to illustrate some interface style elements and possible functionality as a basis for the design process in the project.
As an on-line working document, it is beiing updated periodically to reflect progress in WP 3, and be linked to the other Deliverables in the D3 group as they become available.
The main page of the Deliverable (http://www.ess.co.at/MUTATE/models.html) contains the Executive Summary, a short introduction to the set of MUTATE Interactive Modeling Tools and their respective documentation, an introduction to environmental modeling as spatial analysis, and a number of hyperlinks to the body of on-line multi-media material comprising this deliverable.
These hyper-links include:
(first and second level of hyperlinks only)
The interactive and dynamic environmental modeling tools integrated into the MUTATE bundle address classical environmental problems such as:
urban and industrial air pollution;
example: basic Gaussian screening model ISC-3;
traffic generated air pollution and noise
example: high-resolution kernel based convolution models;
Spatially distributed dynamic simulation or optimisation models
can be understood as an extension of the classical analytical capabilities of GIS.
Most environmental problems do have an obvious spatial dimension. However, they are at the same time usually dynamic, and involve complex and non-linear behavior of a multitude of interacting and evolving elements.
Within the domain of environmental modeling this is addressed by spatially distributed models that describe environmental phenomena in one (for example, in river models), two (land, atmospheric and water quality models, models of population dynamics), or three dimensions (again air and water models). The increasing development and use of spatially distributed models replacing simple spatially aggregated or lumped parameter models is, at least in part, driven by the availability of more and more powerful and affordable computers.
On the other hand, geographical information systems are tools to capture, manipulate, process and display spatial or geo-referenced data. They contain both geometry data (coordinates and topological information) and attribute data, ie., information describing the properties of geometrical spatial objects such as points, lines, and areas.
In GIS, the basic concept is one of location, of spatial distribution and relationship, basic elements are spatial objects. In environmental modeling, by contrast, the basic concept is one of state, expressed in terms of numbers, mass, or energy, of interaction and dynamics; the basic elements are ``species'', which may be biological, chemical, and environmental media such as air, water or sediment.
The successful integration of GIS and environmental models to create dedicated environmental information and, ultimately, decision support systems requires a number of technical and institutional features that need to consider the basic characteristics, assumptions and constraints of these technologies and their users.
