INTRODUCTION

    The Second International Conference on W.K. Clifford's Geometric Algebra and Geographic Information Science on the current state and future directions of the applications of Geometric Algebra (GA) in Geographic Information Science (GIS) will be held from August 23th to August 25th, 2023 at Nanjing Normal University in Nanjing, China. We welcome discussions on topics such as digital twin earth, computation technologies, and quantum mechanics. We invite you to participate in this exciting conference and look forward to meeting and speaking with you in Nanjing in 2023.

CALL FOR PAPERS

    Geographic Information Science (GIS) research is advancing into the era of spatio-temporal big data. This requires the transformation of conventional GIS into an analytical GIS capable of supporting complex model analysis. To meet this challenge, W.K. Clifford's Geometric Algebra (GA) provides a multidimensional, unified, and coordinate-independent theoretical tool for the expression and analysis of GIS data. This tool upgrades calculus, geometry, and signal processing methods to reduce computing complexity while providing useful methods for integrating GIS data models and geographic analysis models. With the development of such tools, challenging applications are emerging. Not only can spatio-temporal unified expressing frameworks of geometric objects be built, but existing algorithms and models can also be effectively embedded.

    This conference will focus on GA-based multidimensional data management and analysis, computation technologies, and reformulation of analysis models (such as ODE, PDE, etc.) as well as software development. The conference aims to bring together leading scientists from both the GIS and GA communities worldwide to discuss the latest frontiers in their respective fields. In addition, there will be a tour of the Key Laboratory for Virtual Geographic Environment, Ministry of Education, to demonstrate the current development of GA-based multi-dimensional GIS. The tour will include demonstrations of the hardware system, software, and applications.

THEMES

    The conference will organize six keynote presentations, each lasting 45 minutes followed by a 15-minute discussion, as well as 15-25 panel sessions, each consisting of 20-minute presentations followed by a 5-minute discussion. These sessions are designed to provide ample opportunities for communication and discussion regarding the latest and most promising directions in the field.

Themes include but are not limited to:

• Fidelity description of the geographical system with multi-domain coupling
• GA-based spatio-temporal unification framework
• GA-based representation of multi-domain data

About Nanjing:

• Lies on the south bank of the Yangtze River, Nanjing, the capital of Jiangsu Province, is one of the most delightful of Chinese cities. About 1 hour railway away from Shanghai, Nanjing is known as the capital city of six dynasties in China's history, with a brilliant cultural heritage.


• Like most major cities in China, modern Nanjing has experienced rapid development, with great dramatic changes over the last two decades. Modern highways, railways and international airport connect the city with most major cities throughout the country and world, and it becomes a sparkling metropolis akin to Shanghai and Beijing with skyscrapers, luxury hotels, fashion shopping malls, supermarkets and colorful nightlife throughout the city. Transport in the city is very convenient with the new metro service in addition to taxis, public buses, tourist special lines and other means of transport. Modern amenities in luxury hotels will make your trip comfortable and dazzling shopping malls and department stores will present you a rich and unforgettable shopping experience. Nanjing is also the home to numerous colleges and universities and a large foreign population. The city is become an international metropolis with new faces every day.
