Open Source Mobile Gis Solutions for Different Application Fields
نویسنده
چکیده
This work deals with use of Open Source technologies for implementing mobile GIS solutions, in order to face the need of moving GIS applications from desktop or web platforms to mobile platforms like PDAs, smartphones, etc. accordingly with the great and growing diffusion of mobile devices and location based services. The implemented mobile GIS is a client-server solution based on a Java servlet inside Apache Tomcat servlet container. The GIS functionalities are obtained by MapServer Java MapScript and by some classes implemented expressly. The paper will discuss the technological aspects of the mobile GIS and will show some specific applications, in particular for archaeological contexts and for issues of civil protection. Moreover, other related topics will be treated: how to make the mobile GIS context aware, how to integrate it with user positioning and object of interest location, how to face some problems (slow loading of images, connection costs) coming from the chosen architecture, how to use it within a local wireless network, how to redefine maps and contexts by GML (Geographic Markup Language).
