An Integrated Visualization System for Spatial Database with Real-Time Text Queries
Min-Ho Song, Hong-Jik Moon, Nakhoon Baek, Kwan‐Hee Yoo · 2015
Geographical features, geometric objects, and even moving objects in the spatial database should be interactively represented on the computer screens, typically through spatial data visualization system. In this paper, we assume that the 3D spatial objects, moving objects and their network data are totally stored into the main-memory DBMS (database management system). Then, they are interactively retrieved through RTT (real-time text) queries. Our visualization system consists of three major components: application part, browser part, and DBMS server part. We combine them into a systematic design, and represent all the details of our implementation. The final results are realized with object rendering techniques, and we also use a few moving object visualization methods. We used RTT queries optimized to our own spatial database, and also optimally enhanced data visualization techniques, to finally achieve the successful screen displays. In near future, we also plan to release commercial products based on our prototype implementations.
