摘要：A Rich Client solution based on Open Source technologies has been implemented in order to realize a mobile GIS application for the exploration of archaeological data.The solution, named RiCOMGIS, is divided in two separate modules: MapGenerator and Front- End Producer. MapGenerator acts as the server-side GIS part of RiCOMGIS. It is basically a Java application ad hoc implemented, which makes use of UMN MapServer Java MapScript. Front-End Producer is responsible for the generation of the graphical user interface (called RiCOMGIS Front-End), produced at run-time using the functionalities offered by the Open Source platform OpenLaszlo.RiCOMGIS Front-End acts also as a client by communicating with MapGenerator through an AJAX (Asynchronous JavaScript and XML)-like mechanism, in order to acquire information from the server or to ask for the generation of only those elements of the interface that have to be updated.RiCOMGIS has several advantages in respect to traditional mobile GIS. First, its modularized structure results in ease of maintenance. Second, no software must be pre-installed on the user device. Third, the possibility to update only specific elements of the interface, in spite of entirely refreshing it at each interaction, improves the user experience, reducing at the same time the bandwidth consumption, that is an important aspect for client-server architectures and software designed to be utilised on mobile devices.The application is still a prototype and its implementation is in progress. However it presents a stable version that provides GIS functionalities and displays maps of a pre-roman archaeological settlement near Como (Italy).
