This paper presents a study on the feasibility, mechanisms and key technology for integrating GIS and OA in the Browser/Server (B/S) architecture, on the basis of a comparative analysis of the independent development model and the integrated development model of GIS and OA. Presently, the development of GIS and OA is mainly based on the two models: Mainframe-Terminal (M -T) model upon stand-alo...

Das Tierseuchennachrichtensystem (TSN) ist das einheitliche Computergestützte nationale Berichtssystem für Tierseuchen und Tierkrankheiten, welches seit 1995 in allen Veterinärbehörden Deutschlands genutzt wird. Seit der Einführung der ersten WindowsVersion von TSN im Dezember 2000 wurde das System zu einem Krisenmanagementsystem weiterentwickelt. Neben der Integration von Internet-Technologien...

background: although experiments on water quality are time consuming and expensive, models are often employed as supplement to simulate water quality. artificial neural network (ann) is an efficient tool in hydrologic studies, yet it cannot predetermine its results in the forms of maps and geo-referenced data. methods: in this study, ann was applied to simulate groundwater quality and geographi...

Today information systems play key role in new century, geographical information system (GIS) as a special class of information system. Now we are moving wired to wireless network, that is mobile environment shown in fig2 (any where any time and any thing computing), plays key role in this new century. In this application mobile GIS, which will be a network environment, is proposed, which can p...

The purpose of this paper is to develop the GIS educational environment in training program using open-source GIS software. First, we have verified the substitutability of laboratory exercise materials at our university from commercial GIS to open-source GIS software. Next, we grasp the improvement situation of the free spatial data that are opened to the public by the government and present th...

Many valuable models and tools developed by scientists are often inaccessible to their potential users because of non-existent sharing infrastructure or lack of documentation. Case in point is the FUTure Urban-Regional Environment Simulation (FUTURES), a patch-based land change model for generating scenario-based regional forecasts of urban growth pattern. Despite a highimpact publication, few ...

Sustainable management of highly dynamic coastal topography with fast moving sand dunes, eroding shoreline and anthropogenic changes to bathymetry and beaches represent significant challenges for coastal management. Modern mapping technologies bring capabilities to monitor this dynamic environment with unprecedented spatial and temporal detail. The general research strategy for coastal areas [1...

The aim of this paper is to describe the evolution of GIS applications development process, based on the SDKs transformations, especially by considering the ESRI ArcGIS development platform. On the one hand, this study relies on our previous experience in GIS software engineering; on the other hand, it reflects the features and particularities of the projects we conducted within the bachelor an...

In this work, we present an application architecture that integrates geographic information systems (GIS) data into an application that supports several advanced capabilities. This application is implemented on the previously developed Interactive Land Use VRML Application (ILUVA). The application features the the integration of dynamic content generated by a server and support of live updates....
