GSCI Friday Seminar Series - Big Data Analytics on Big Spatial Database
Nowadays, location-based services (LBSs), which refer to those services that are based on location (or spatial) data, are broadly used in our daily life. In this talk, we will talk about the recent development of LBSs. Some examples are "Search-nearby", "Spatial Crowdsourcing", "Trace Tracking" and
"Shortest Distance". We will focus on presenting some important results about shortest distance queries, one fundamental LBS, in the new context of the three-dimensional spatial database which receives a lot of attention from both the academic community and the industry community like Microsoft’s Bing Maps and Google Earth.
