“…However savings from avoiding conventional XML parsing/serializing processing is still significant. We also investigate this non-mobile case [25]. We compare our system with the conventional SOAP communication model, and as expected, empirical results based on our performance model show substantial performance gains by adapting the approach.…”

“…This provides the online browsing capability for very highresolution 2D images without the cost of downloading the entire full-resolution image to the client. 10 Since there is no Open Geospatial Consortium specification for a tiled web map service standard, Google developed its own based on a similar tiling scheme with its Google Map service. Google Maps Imagery (Google Maps) makes use of a quadtree system for storing and accessing its pyramid of imagery tiles.…”

One of the most important features of a tourist mapping service is its ability to speed up the process of large image navigation. To achieve this goal, most techniques use interactive compressions such as Multiresolution Seamless Image Database, ERMapper compressed wavelet, and JPEG2000. An alternative approach is proposed in this article using quadtree structures, which allows direct access to information and avoids compression and decompression operations. The proposed strategy is designed to function within a framework of interoperability and integration with the universal search platforms of mapping services. In this study, a photogrammetric image of the entire Andalusia region is used to assess a strategy of cutting and merging images and evaluate the geometric accuracy of the raster data. The proposed approach is shown to result in errors of less than 2.5 m at more than 90% of the control points.

“…There have been some success stories from the intersection field of grid computing and GIS. In some studies, the grid-computing technology is used to achieve effective geospatial data management, complex geospatial analyses, and parallel processing on remote sensing data (Shen et al 2004, Aydin et al 2008, Fang et al 2008.…”

Grid computing is deemed as a good solution to the digital earth infrastructure. Various geographically dispersed geospatial resources can be connected and merged into a 'supercomputer' by using the grid-computing technology. On the other side, geosensor networks offer a new perspective for collecting physical data dynamically and modeling a real-time virtual world. Integrating geosensor networks and grid computing in geosensor grid can be compared to equipping the geospatial information grid with 'eyes' and 'ears.' Thus, real-time information in the physical world can be processed, correlated, and modeled to enable complex and advanced geospatial analyses on geosensor grid with capability of high-performance computation. There are several issues and challenges that need to be overcome before geosensor grid comes true. In this paper, we propose an integrated framework, comprising the geosensor network layer, the grid layer and the application layer, to address these design issues. Key technologies of the geosensor grid framework are discussed. And, a geosensor grid testbed is set up to illustrate the proposed framework and improve our geosensor grid design.
