Research and implementation of massive data atlas visual strategy

Abstract

In order to solve the display problem with massive data atlas, researchers propose five kinds of visualization strategy to improve the display efficiency in this paper. By using the strategy of establishing the atlas map frame index, hierarchical visualization, real-time dynamic projection, double buffering + multi-threading data dynamic annotation, local cache based on spatial data mining visualization, researchers basically solve the problems existing in the process of multi-source heterogeneous mass data atlas display. The strategy has achieved on the MapGIS K9-based platform and successfully applied to the basis of the outcome of mapping system of the national fundamental geographic information center. Researchers found that the display strategy is significantly more efficient than traditional visualization strategy. Thus, the effectiveness and accuracy of the algorithm are verified. © 2013 Springer Science+Business Media New York.
