Web-GIS has played an important role in supporting accesses, visualization and analysis of geospatial data over the Web for the past two decades. However, most of existing WebGIS software stacks are not able to exploit increasingly available parallel computing power and provide the desired high performance to support more complex applications on large-scale geospatial data. Built on top our pas...

In higher education research, computer and information technologies are getting increased consideration and attention. These technologies can be integrated into the design education through taking into account a scaffolding mechanism, which will support activities of teaching/learning in a distributed environment. This research presents a digital-based scaffolding geographic information systems...

The tanker Nakhodka oil spill in the Sea of Japan was happened on January 2 1997 and this accident caused serious environmental damages. After the accident, discussions and collaborations involving citizens and government have been started to make significant steps to protect natural environment of river banks, mountains and hills in the vicinity of human residents and these activities seem to ...

A key aim of government, as evidenced by the recent publication of a White Paper entitled “Communities in Control – Real people real power”, is to enhance the involvement of local communities in the decision making processes of their local councils and increase the power of local residents to influence change in their area. Fundamental to this process is the provision of timely access to inform...

TKA-TPA data management is performed conventionally and inaccurately. Accordingly, it may result in considerable loss. Data collection for by BADKO Kasihan Bantul Yogyakarta still carried out conventionally. Therefore, this study supports management, reporting, mapping, publication. A Web Geographic Information System (GIS) was created using the CodeIgniter framework with Hypertext Preprocessor...

The GenW2 project (Generalization for portrayal in Web and Wireless mapping) has recently started and aims at developing new methods for web and wireless mapping with the main focus on integration of heterogeneous information and on-the-fly map generalization in a mobile context. The poster discusses the first step of a proposed methodological framework for future mobile GIS and mapping scenarios.

Technically the spatial non-interoperability problem associated with current geospatial processing systems can be categorized as data and access non-interoperability. In GIS community, Open GIS Consortium (OGC) geospatial Web services have been introduced to overcome spatial noninteroperability problem associated with most geospatial processing systems. At the same time, in Information Technolo...

Geographic information is critical to effective and collaborative decision making in earthrelated disaster planning, crisis management and early-warning systems. Decision making in Geographic Information Systems (GIS) increasingly relies on analyses of spatial data in mapbased formats. Maps are complex structures composed of layers created from distributed heterogeneous data and computation res...

This paper presents the design and development of an open source web-based Geographical Information System allowing users to visualise, customise and interact with spatial data within their web browser. The developed application shows that by using solely Open Source software it was possible to develop a customisable web based GIS application that provides functions necessary to convey health a...
