DGIS is designed and implemented as a dynamic raster GIS in a fully integrated systems strategy using theory of modelling and simulation, discrete event systems specifications, and knowledge-based simulation methodologies. The approach accommodates the representations and operators of current GIS in a broader systems representation scheme that includes the constructs for handling continuous time, model base, multiple resolution, hierarchy, taxonomy, variable structure, and intelligent agents. DGIS is defined as an endomorphic system that can be transformed by the user into different, application-specific, spatial dynamic simulation environments depending on the models selected to fit the various aspects of its structure. In this paper we describe the theory, methods, and technologies upon which the system is designed and implemented and discuss how it can support complex spatial simulations. To probe operational applicability, an instance of DGIS is generated: a fire spread simulation environment, which is tested in the simulation of 15 real fire events.

Building-up a burned area monitoring system based on Earth observation data / J.U. Paul (31/05/1999)

A large percentage of these fires - 43% (DGF estimations) - are due to arson, which most of the times is related to land use change purposes. As an attempting to reduce the amount of intentional fires, the Portuguese legislation includes a set of laws that regulate the landuse change in areas devastated by forest fires. However, the control of these areas on the field is very expensive and time consuming, resulting in an ineffective procedure. In this study, we propose a more efficient and cost effective procedure to control the compliance of the legislation on burnt forest areas. This procedure is based on a system, BAMS (Burned Areas Monitoring System), built on a GIS that uses multi-temporal dataset of satellite images for detecting burned areas, and for characterizing land use before and after fire occurrence.
