Towards the automatic generation of web GIS
Proceedings of the 15th annual ACM international symposium on Advances in geographic information systems, 2007In the present paper, we propose an approach for the development of Web GIS based on WebML, a high-level, formal visual language specifically conceived to design data-intensive Web applications. The proposal is motivated by the observation that Web GIS can be considered as a particular class of data-intensive Web applications. In the paper, we describe

Data quality descriptions play a key role in Geographic Information Systems (GIS). With the availability of geographic data sources over the internet, there is a real issue to be addressed, that is how to ensure quality of web-based heterogeneous GIS.

Sensor Web Oriented Web-Based GIS
2008Web-Based GIS has brought a lot of convenience to the public. However, traditional Web-Based GIS cannot meet the needs in applications that request for many different data types and real-time updates. A Sensor Web is a computer accessible network of many, spatially distributed devices using sensors to monitor conditions at different locations.

The role of the map in a Web-GIS environment
Journal of Geographical Systems, 2004The World Wide Web has changed the perspective on the role that maps can play. Their traditional function remains, e.g. to represent an abstraction of a selected part of reality to offer insight into geospatial patterns and relations. Additionally the map can be an important part of a search engine, especially in the context of geospatial data ...

Spatial QBE Interface for Web GIS
The Fifth International Conference on Computer and Information Technology (CIT'05), 2005Many applications use geographic data, such as land management, urban planning, tourism, vehicle guidance and navigation, and e-commerce. A related research problem is to define user-friendly interfaces for Web GIS. There is a need for the definition of simple and user-friendly interfaces to allow the users to pose ad-hoc queries. Query-by-example (QBE)

On Performance Evaluation of Web GIS Applications
16th International Workshop on Database and Expert Systems Applications (DEXA'05), 2005Geographical information systems (GIS) deal with large volume of datasets. Hence, one of the main concerns on Web GIS is related to performance issues, as these datasets need to migrate, as fast as possible, from server to client tiers. Therefore, in order to maximize performance on Web GIS it is necessary to apply optimization techniques.
