SIGRE - An Autonomic Spatial Information Grid Runtime Environment for Geo-computation
نویسندگان
چکیده
Spatial Information Grid is a kind of application grid which tries to connect resources such as computer, data sources, and processing algorithms, and builds a distributed, robust, flexible and powerful infrastructure for geocomputation. It needs a powerful and easy-to-use running environment. In this paper, an autonomic runtime environment for geo-computation is proposed and named SIGRE — the Spatial Information Grid Runtime Environment. Based on it, SIG resources can be distributed, discovered, and matched autonomically. And a distributed, flexible and powerful data infrastructure which can distribute data with different types, different sources, and different goals in a uniform interface easily and flexibly is founded. Based on the implementation of SIGRE by java language, a SIG testbed is constructed, and the test on it shows that SIGRE can provide a powerful, easy-to-use, robust and autonomic runtime environment for SIG, and developers can develop SIG resources and SIG applications on SIGRE easily and quickly.

Surface runoff estimation in an upper watershed using geo-spatial based soil conservation service-curve number method
Runoff assessment and estimation is crucial for watershed management as it provides information that is needed to expedite the course of watershed planning and development. The most commonly used model due to its simplicity and versatility in runoff estimation is the soil conservation service curve number developed by the United States Department of Agriculture. The study estimates the surface ...
متن کاملA taxonomy and survey on autonomic management of applications in grid computing environments
In Grid computing environments, the availability, performance, and state of resources, applications, services, and data undergo continuous changes during the life cycle of an application. Uncertainty is a fact in Grid environments, which is triggered by multiple factors, including: (1) failures, (2) dynamism, (3) incomplete global knowledge, and (4) heterogeneity. Unfortunately, the existing Gr...

City components are important elements of a city, and their identification plays a key role in digital city management. Various identification codes have been proposed by different departments and systems over the years, however, their application has been partly hindered by the lack of a unified coding framework. The use of a code identifying a city component for unified management and geospat...

After the setup of spatial data infrastructure (SDI) and national information infrastructure (NII) in many countries geo-services become one of the most important and attractive tasks. With the integration of GPS, GIS and Remote Sensing (RS) we can principally answer any geo-spatial related question: when and where what object has which changes? An intelligent Geo-service agent would provide th...
