Ideally, spatial ecological models should be easily linked to a geographic information system (GIS). In the past, these two have not been well integrated for scientific uses. Lack of true integration hinders the ability of managers and scientists to create interactive, GIS-based models for management and research. However, GIS packages are starting to provide programming constructs, by exposing...

Geographical Information System (GIS) is a tool that has recently been applied to better understand spatial disease distributions. Using meteorological, social, sanitation, mollusc distribution data and remote sensing variables, this study aimed to further develop the GIS technology by creating a model for the spatial distribution of schistosomiasis and to apply this model to an area with rural...

Spill Management Information System (SMIS) is a geographic information system (GIS)-based decision support system designed to effectively manage the risks associated with accidental or intentional releases of a hazardous material into an inland waterway. SMIS provides critical planning and impact information to emergency responders in anticipation of, or following such an incident. SMIS couples...

An important research trend in databases is to handle different types of uncertainty at both conceptual and logical levels for various non-traditional applications that may involve imprecision and uncertainty that have been difficult to integrate cohesively in simple database models. In this study we describe how to conceptually model complex and uncertain information at the conceptual level (b...

In this paper, we propose two methods aiming at updating Geographic Information System (GIS) urban maps using satellite high-resolution remote sensed images. Both methods are based on the input of a priori knowledge provided by GIS data, and a Digital Surface Model (DSM). This article introduces theoretical aspects of our methods; implementation is currently ongoing.

This study focuses on the possibilities and the limits of a prospective GIS land cover modelling applied to two case studies (France and Spain). The methodology, based on available GIS tools, consists of using earlier land cover maps and relevant environmental factors (calibration data) to model actual, known land cover to validate the model. The model aggregates Markov chain analysis for time ...

Geographic information system (GIS) is a computer application system, which possesses the ability of manipulating spatial information and has been used in many fields related with the spatial information management. Many methods and models have been established for analyzing animal diseases distribution models and temporal-spatial transmission models. Great benefits have been gained from the ap...

A geographic Information System (GIS) is an important tool for monitoring phenomena in space. In addition to studying diseases over time, this system helps us study distributions of diseases. The known global center with leishmaniosis disease almost entirely between 28- 42 degrees north latitudes. research on disease, a clearer picture the process changes and spatial distribution can be provide...

The completeness and versatility of spatial data models and associated operations serve as the foundation of any GIS. The raster data model and the cartographic modeling framework provide the representation and operations for analyzing geographic fields. The current GIS raster data model and cartographic modeling operations are limited in that all the attributes measured at each location in fie...
