“…Multiuser collaboration is playing its role in many works involving stakeholders from different departments and organizations, in which mapmaking sometimes play a main role for giving visual information for the support to decision-making [3]. Web technology is rapidly expanding its range and has made it possible to take decisions over the web.…”

Co-PPGIS has a wide variety of applications like municipal planning, emergency response, public health and security, etc. The main focus of this paper is on the development and design of a web collaborative PPGIS (Co-PPGIS) infrastructure. As part of municipality's planning and management services, Co-PPGIS is developed for real-time map sharing application system. Co-PPGIS is an effective and essential online meeting system for supporting group collaborations on geographic information such as maps and imageries and capturing and sharing of local/domain knowledge in real time. Co-PPGIS permits amalgamation of geospatial data and collaborator's input in the form of geo-referenced notations. It incorporates coherent components such as map sharing, real-time chat, video conferencing, and geo-referenced textual and graphical notations. The study aims to focus on public participation and geo-collaboration facilitated with information sharing, interactive geo-conferencing, real-time map, and data sharing with tools to draw features or add annotation to the map while discussions, uploading documents, and live communication. Co-PPGIS provides an efficient and reliable platform that will significantly reduce the time to acquire, process, and analyze data. The significance of this study is to contribute to existing public participation practices, to municipal planning, to decisionmaking, or to geographic information science.

“…Issues of robustness, fault tolerance, network disconnection, and late joiners have been investigated for some time (e.g., [1,3,5,11,16,29]), but the user view of groupware disconnection has not been widely considered. Gutwin et al [13] recently provided an overview of the problem from this perspective, stating two main factors for handling disconnection: the time scale of the absence, and the phase of the disconnection (specifically identifying a disconnection, determining what to do during the absence, and determining what to do on reconnection.)…”

“…Toolkit approaches to the latecomer problem can generally be divided into those that provide state-based recovery (e.g., Habanero [17] or Suite [9]), those that provide replay-based recovery (e.g., Chung et al's accommodation service [4] or XTV [5]), and those that combine both approaches (e.g., DreamObjects [19]). …”

Disconnection and reconnection are common problems for users of synchronous groupware, but these problems are not easy for developers to handle because of the wide range of scenarios and timeframes that must be considered. We have developed a new toolkit called DiscoTech that helps programmers deal with disconnection. The toolkit is based on five design dimensions that determine how stored information can be manipulated as the system waits for an absent user to rejoin, and how information should be replayed upon reconnection. DiscoTech provides a plug-in architecture to handle a wide variety of behaviours that developers may need during disconnection; these plug-ins range from fully generic tools to customized strategies with full knowledge of the groupware application. We present the design of the DiscoTech toolkit, show examples of its use, and provide evidence that it covers a broad range of situations, imposes minimal performance overhead, and is easy for programmers to learn. DiscoTech handles a wider range of issues than previous toolkits, without requiring undue effort, and provides a practical way to improve the real-world usability of synchronous groupware.
