报告题目：A visual exploration of the Geospatial data
报告人：Zhifeng Bao（Assistant Professor，School of Computer Science & IT, RMIT University, Australia）
In this talk, I will first introduce the most recent system we have built for an interactive and visualized exploration of the location-centered real estate data in Australia for the last ten years (http://188.8.131.52/). Then, I will adopt a top-down approach from real applications to fundamental research problems, to illustrate several research achievements on seamlessly combining data visualization and data management techniques to enhance the usability of geospatial data. In particular: (1) problem - how to continuously (7*24) monitor the trending areas and houses based on user’s spatial range and KNN queries in streaming fashion; significance - facilitate buyers to find a desired property and for sellers to find the best time to enter the market to sell the house. (2) Problem - How to achieve Efﬁcient selection of Geospatial data on maps for Interactive Visualized Exploration; significance - to achieve the goal of representativeness, visibility, zoom consistency and movement consistency in one basket. (3) Problem – How different visualization designs help user find interesting patterns, help data cleaning, etc. Last, if time allows I will talk about our recent work on exploring the activity trajectory data for interactive trip planning.
