Spatial analysis is a fundamental function for geographic information systems. Although it is popular in many commercial desktop GIS packages, this capability is very limited in a Web-GIS environment, especially when relational database is used for geospatial data management. This paper proposes and prototypes a methodology to enhance spatial analysis capabilities of Web-GIS by extending and en...

This paper examines the design and implementation of ParcBIT, a multimedia GIS CD-ROM presenting the information required for the development of a Master Plan for a Technological Park in the island of Majorca (Spain). The CD-ROM is the information resource of an international competition for Master Plan proposals in which world leading architects took part. Environmentally conscious planning is...

Clusters of genes acquired by lateral gene transfer in microbial genomes, are broadly referred to as genomic islands (GIs). GIs often carry genes important for genome evolution and adaptation to niches, such as genes involved in pathogenesis and antibiotic resistance. Therefore, GI prediction has gradually become an important part of microbial genome analysis. Despite inherent difficulties in i...

Selecting a Geographic Information System (GIS) based on Free Software (FS) is a difficult task vis-à-vis its technological complexity, the wide range of this type of systems and their functionalities. Therefore, provides a set of quality characteristics used to evaluate FS-GIS. This set of characteristics is presented on the product perspective of the Systemic Software Quality Model (MOSCA), w...
