With the advance of the World-Wide Web (WWW) technology, people can easily share content on the Web, including geospatial data and web services. Thus, the “big geospatial data management” issues start attracting attention. Among the big geospatial data issues, this research focuses on discovering distributed geospatial resources. As resources are scattered on the WWW, users cannot find resource...

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...

A catalogue service facilitates sharing, discovery, retrieval, management of, and access to large volumes of distributed geospatial resources, for example data, services, applications, and their replicas on the Internet. Grid computing provides an infrastructure for effective use of computing, storage, and other resources available online. The Open Geospatial Consortium has proposed a catalogue...

The first Workshop on Security and Privacy in GIS and LBS (SPRINGL 2008) was organized on November 4, 2008 at Irvine (CA) in conjunction with the SIGSPATIAL International Conference on Advances in Geographic Information Systems (ACM GIS 2008). The goal of the SPRINGL workshop series is to provide a forum for researchers working in the area of geospatial data security and privacy. Both security ...

Geospatial semantics is a broad field that involves a variety of research areas. The term semantics refers to the meaning of things, and is in contrast with the term syntactics. Accordingly, studies on geospatial semantics usually focus on understanding the meaning of geographic entities as well as their counterparts in the cognitive and digital world, such as cognitive geographic concepts and ...

Boolean division, and hence Boolean substitution, produces better result than algebraic division and substitution. However, due to the lack of an e cient Boolean division algorithm, Boolean substitution has rarely been used. We present an e cient Boolean division and substitution algorithm. Our technique is based on the philosophy of redundancy addition and removal. By adding multiple wires/gat...

We propose a fast hardware algorithm for division in GF(2) based on the extended Euclid’s algorithm. The algorithm requires only one iteration to perform the operations that correspond to the ones performed in two iterations of previously reported division algorithms. Since the algorithm performs modular reductions in parallel by changing the order of execution of the operations, a circuit base...
