Visualization of Geo-referenced Entity: An Aspect-Oriented Pattern

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Web Geographic Information Systems (GIS) are systems composed by software, hardware, spatial data and computing operations, which aim to collect, model, store, share, retrieve, manipulate and display geographically referenced data. The development of online geospatial applications is currently on the rise, but this type of application often involves dealing with concerns (i.e., properties) which are inherently volatile, implying a considerable effort for system evolution. Nevertheless, geospatial concerns (e.g., geographically locating dispersed staff needed for a meeting), although changeable, are reusable. However, lack of modularization in software artifacts (including system’s models) can compromise reusability. In this context, the use of requirements analysis patterns, enriched with aspect-oriented modeling techniques, can support reusability and improve modularity. In this paper, we introduce a requirements analysis pattern for visualizing geo-referenced entities. This pattern is obtained from the domain analysis of Web GIS applications and described using a template which is supported by a comprehensive tool, presented in this paper.
