In this paper, Aiming at the characteristic of simple feature class polygon aggregation in multi-core environment, the improved algorithm divides spatial data for the polygon in simple feature class using STR (Sort-Tile-Recursive) tree index, it reduces the number of reading disk during searching polygons in the spatial database. The algorithm is based on the feature of STR-tree index, first of all...
This paper discussed the key technologies for building a Geospatial Information Grid service workflow and describes the design and implementation of a Grid GIS service integration and hybrid invocation prototype framework: the MapGIS Grid Workflow Framework (MGWF). First, we discussed the WSRF based GIS function encapsulation details for legacy GIS system. Then we researched on the Grid GIS services...
Spatial information grid is established in the environment of distributed grid. With the capability of offering required services, it can immediately customize specific services and resolve the problem in sharing and cooperation of distributed massive heterogeneous spatial data. Based on spatial information grid, aim of resource and information sharing mechanism is aggregating computing resource,...
The ever-increasing of the large geospatial datasets and the widely application of the complex geocomputation make the parallel processing of GIS an important component of high-performance computing. The paper introduces a two-phase load-balancing scheme for the parallel GIS operations in distributed environment. The paper focus on the parallel framework design and parallel strategy implement of the...
