Geospatial information catalogs are complex infrastructures that store and publish geographic information. They are an important part of Geographic Information Systems (GIS), systems that manage geospatial data for a wide variety of application domains. To be useful, a catalog must ef ciently support discovery and retrieval of geospatial information, working as a key component for planning and ...

A wide variety of systems from many different fields use geospatial data to represent physical environments. These systems, and the data on which they operate, are not only becoming more complex, but they are increasingly being connected together. Although each system may be interested in very different aspects of the environment, the geospatial data they use must be consistent and correlated w...

Geographic Information System (GIS) is one of the important elements of the IT infrastructure of local governments. In recent years, in the consequence of development of Web-based GIS technology, the definition of GIS has been changing to “Geospatial Information Service”. For a local government, the geospatial information service is becoming an important IT system in the field of information se...

Recent advances in geospatial technologies have made available large amount of geospatial data. Meanwhile, new developments in Internet and communication technologies created a shift from isolated geospatial databases to ad hoc networks of geospatial data sources, where data sources can join or leave the network, and form groups to share data and services. However, effective integration and sha...

Geospatial metadata have long played an important role in the management of geospatial datasets. Often employed by institutions to organise, maintain and document their geographic resources internally, metadata may also provide a vehicle for exposing marketable data assets externally when contributed to on-line geospatial exchange initiatives. In spite of the numerous benefits it affords, obsta...

Geospatial data inform decision makers. An economic model that involves application of spatial and temporal scientific, technical, and economic data in decision making is described. The value of information (VOI) contained in geospatial data is the difference between the net benefits (in present value terms) of a decision with and without the information. A range of technologies is used to coll...

The daily use of geospatial technology, such as the global positioning system (GPS), geographic information systems (GIS), and remote sensing (RS), is increasing. The use of geospatial technology in disaster management is a natural fit because almost every aspect of a disaster is referenced by location. This paper presents the results of a recent web-based survey of disaster management practiti...

The volume, complexity, variability and accessibility of geospatial of digital geospatial data pose formidable challenges for the National Archives. Scientific and engineering communities faces many of the same challenges in managing large, complex digital data collections. This study examines gridded and vector geospatial data through the prism of scientific data management, with particular em...

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...

Seismic site effects are influenced mainly by geospatial uncertainties corresponding to geological or geotechnical spatial variance. Therefore, the development of a geospatial database is essential to characterize site-specific geotechnical information in multiscale areas and to optimize geospatial zonation methods with potentially high degrees of spatial variability based on trial-and-error ge...
