A theoretical approach to the use of cyberinfrastructure in geographical analysis

Abstract: This paper presents a theoretical approach that has been developed to capture the computational intensity and computing resource requirements of geographical data and analysis methods. These requirements are then transformed into a common framework, a grid-based representation of a spatial computational domain, which supports the efficient use of emerging cyberinfrastructure environments. Two key types of transformational functions (data-centric and operation-centric) are identified and their relationships are… Show more

“…Typical efforts can be demonstrated in spatial interpolation [26][27][28], spatial statistics [26,[29][30][31], spatial visualization [32], viewshed analysis [33,34], spatial simulation [35,36], geocollaboration [27,37], etc. In most cases, the optimization strategy used in one algorithm may not work for another.…”

“…These fundamental solutions can be the theoretical approaches, such as the grid-based representation of a spatial computational domain [27,30,38], the framework for multilayered libraries between the computing resources and the serial geographic algorithms [39], and the research on the distributed geographic information processing (DGIP) which provides a guiding methodology and principles for implementing geospatial middleware [40][41][42], or the general libraries for processing a particular category of applications, such as the pRPL (parallel raster processing programming library) [43], the PaRGO (parallel raster-based geocomputation operators) [44], etc. In summary, the implementations of these fundamental solutions are mostly based on the powerful computing technologies, including grid computing, cloud computing, and parallel computing.…”

“…In addition, the predictive scaling algorithm sheds lights on automatically scaling cloud computing resources for other data processing platforms beyond Hadoop. Finally, we believe that the proposed approach offers a valuable reference in planning better performed spatial applications in a cyberinfrastructure environment to more cost-efficiently address data-and computational intensity challenges in geospatial domains [40,41].…”
