W.K. Clifford’s Geometric Algebra and Geographical Information Science: Development and Applications (GAGIS) (Special Section of the 33rd International Geographical Congress) was Held Successfully in our School during 8.25-8.26, 2016. It was co-hosted by the Key Laboratory of Virtual Geographic Environment (Nanjing Normal University), Ministry of Education; State Key Laboratory Cultivation Base of Geographic Environment Evolution (Jiangsu Province) and School of Geographic Science (Nanjing Normal University). Professor Yuan Linwang, as the initiator and organizer, hosted the opening ceremony and welcomed more than 20 scholars from Germany, Austria, the United States, the United Kingdom, Japan, Vietnam, China, etc.
Scholars from different fields shown their latest research findings. Japanese professor, Mr Eckhard Hitzer, co-chair of the conference,elaborated the application of Geometric Algebra in 21st century. Dr Hildenbrand from Germany explained parallel computing strategy of Geometric Algebra and realized his plan based on hardwares like FPGA. Austrian professor, Mr Werner Benger put forward a F5 model for processing and visualizing massive data. American professor, Mr Staples, constructed a shortest path algorithm based on Graph Calculation Operator. Cofounder of Common Geometric Algebra, Professor Li Hongbo from Chinese Academy of Mathmatics and System Sciences, introduced the new progress of 3D projective geometry R(3,3) model. Associate professor, Mr Yu Zhaoyuan from our school, explained the latest results for applying Geometric Algebra in multi-dimension and spatial-temporal unified GIS. Professor Pham Tuan (Vietnam) and Dr. Kanta Tachibana (Japan) described how to recognize human activities with the combination of Conformal Geometric Algebra and Principle Component Regression.Associate professor, Mr Zhou Liangchen from our school, constructed global discrete grids (E-QTM) based on QTM grids to realize the synchronization support for data management and model calculation. Dr. Gu Yanhui from our school, researched on information retrieval for integrated space and text information. Dr. Zhang Jiyi from China University of Mining and Technology, discussed a construction of 3D cadastral data model based on Geometric Algebra.
Besides, deputy director of our key lab, professor Sheng Yehua, invited all researchers to visit the Virtual Geographic Environment laboratory, and introduced instruments and software systems of our lab in detail. Meanwhile, other teams also presented their research results to the attendee. During the discussing session, researchers from different countries proposed their understandings and suggestions, and exchanged their views with comprehensive explain. The conference was held successfully, and presented the latest applications of Geometric Algebra in different fields. It can acclerate the development of Geometric Algebra and provide platforms for multi-displinary communication and cooperation.
