报告人简介:

Hanan Samet is a Professor in the Department of Computer Science at the University of Maryland. He received the B.S. degree in engineering from UCLA, and the M.S. Degree in operations research and Ph.D. degrees in computer science from Stanford University.

He is on the editorial boards of GeoInformatica, Journal of Visual Languages and Computing, and Image Understanding. He is the founding chair of the ACM SIG on Spatial Information. He has served as the co-general chair of the 2007 and 2008 ACM SIGSPATIAL Conference on Geographic Information Systems (ACM GIS). He has also served on the program committees of many conferences, symposia, and workshops.

His research interests include data structures, computer graphics, geographic information systems, computer vision, robotics, database management systems, and programming languages, and he is the author of over 300 publications on these topics. He is the author of the recent book titled "Foundations of Multidimensional and Metric Data Structures" published by Morgan-Kaufmann, an imprint of Elsevier, in 2006, an award winner in the 2006 best book in Computer and Information Science competition of the Professional and Scholarly Publishers (PSP) ,Group of the American Publishers Association (AAP), and of the first two books on spatial data structures titled "Design and Analysis of Spatial Data Structures", and Applications of Spatial Data Structures: Computer Graphics, Image Processing, and GIS", both published by Addison-Wesley in 1990.

He is a Fellow of the IEEE, ACM, AAAS, and IAPR (International Association for Pattern Recognition), and was also elected to the ACM Council in 1989-1991 where he served as the Capital Region Representative. He received a best paper award in the 2008 ACM SIGMOD and SIGSPATIAL Conferences.

报告内容:

An introduction is given to the spatial database issues involved in the design of geographic information systems (GIS) from the perspective of a computer scientist.  Some of the topics to be discussed include the nature of a GIS and the functionalities that are desired in such systems.  Representation issues will also be reviewed.  The emphasis will be on indexing methods as well as the integration of spatial and nonspatial data.  Demos will be shown of the SAND Spatial Browser (http://www.cs.umd.edu/~brabec/sandjava) as well as the VASCO JAVA applet (http://www.cs.umd.edu/~hjs/quadtree/index.html) which illustrates these ideas.
