Frameworks and Patterns are important instruments that enable the reuse of successful software solutions in recurrent problems. Geographic information systems, on the other hand, are usually designed by people with only little knowledge of database modeling techniques. Therefore, we believe that analysis patterns and conceptual frameworks can both(More)
This paper describes the problems found in geographic databases design during the conceptual modeling of real world elements that are related by a network structure. It is believed that is possible to reach a better quality of the geographical data if spatial integrity constraints about the elements on a network are specified in a conceptual level. Hence,(More)
Concern for environmental issues has become a reality in all sectors of society, mainly among researchers and professionals who work directly with environmental status. In this context, several studies have been undertaken on sustainable development of the Brazilian Amazon, generating a large amount of data and information. Environmental area(More)
This paper describes the development of an open source CASE tool, the ArgoCASEGEO, and its modular architecture. The ArgoCASEGEO allows the geographic database modelling based on the UML-GeoFrame conceptual model that is specific for Geographic Information Systems applications. The data dictionary associated to the modelled schema is stored as a XML/XMI(More)
An analysis pattern is any part of a requirement analysis specification that can be reused in the design of other information systems as well. Urban management systems (e.g.: Tax Control Systems, Urban Transportation System) are implemented in a similar way for many counties. This paper proposes three analysis patterns that make possible the reuse of(More)
Patterns have been employed as a mechanism for reuse in several phases of software development. Analysis patterns consist of artifacts for reuse during the requirements analysis and conceptual modeling. However, they are generally, documented in a textual manner which is not precise to be treated by a computer, thus limiting the dissemination and a wider(More)
Analysis patterns are reusable computational artifacts, aimed at the analysis stage of the process of software development. Although the analysis patterns can facilitate the work of analysts and programmers adding value through reuse of proven useful and tested ideas, the access to them is still very poor because of the way they are usually described and(More)
Volunteered Geographic Information (VGI) is a Web phenomenon known as “user-generated content”, which involves resources from Web 2.0 and geographic data. Geobrowsers are websites that collect and provide VGI. These systems, however, do not follow norms or standards for data collection or documentation, which makes it difficult to recover such data and(More)
