Disaster prevention and management is a complicated task that often involves a tremendous volume of heterogeneous data from various resources. With its dynamic and distributed nature, service technology appears to be a good candidate for removing the communication barriers between various organizations and for facilitating the integration and sharing of distributed data. For it to succeed, howe...

3D geospatial information systems should provide efficient spatial analysis tools and able to use all capabilities of the third dimension, and a visualization. Currently, many human activities make steps toward the third dimension like land use, urban and landscape planning, cadastre, environmental monitoring, transportation monitoring, real estate market, military applications, etc. To reflect...

Data quality is a common concern in a wide range of domains. Since agriculture plays an important role in the Brazilian economy, it is crucial that the data be useful and with a proper level of quality for the decision making process, planning activities, among others. Nevertheless, this requirement is not often taken into account when different systems and databases are modeled. This work pres...

Big data has now become a strong focus of global interest that is increasingly attracting the attention of academia, industry, government and other organizations. Big data can be situated in the disciplinary area of traditional geospatial data handling theory and methods. The increasing volume and varying format of collected geospatial big data presents challenges in storing, managing, processi...

DEFINITION Network GIS Performance (NGP) refers to the level of Quality of Services (QoS) of a Network GIS. NGP includes both the efficient use of Network GIS resources (CPU, memory, massive storage, geospatial data and geospatial services) and the perception of speed of a Network GIS [1]. Network GIS is a GIS where the geospatial data and geospatial processing are distributed across a computer...

Although the fast development of OGC (Open Geospatial Consortium) WFS (Web Feature Service) technologies has undoubtedly improved the sharing and synchronization of feature-level geospatial information across diverse resources, literature shows that there are still apparent limitations in the current implementation of OGC WFSs. Currently, the implementation of OGC WFSs only emphasizes syntactic...
