Dear GIS IDEAS 2024 secretariat team,

I hope this message finds you well. My name is Vu Khac Hung, and I am writing from Vietnam. I have submitted a paper with the paper ID *88007 * and also paid the registration fee.

I kindly request an official invitation letter. This letter is crucial for completing the required administrative procedures at my university to support my participation in the conference. As the conference is taking place next week, I would greatly appreciate receiving the letter at the earliest possible time.

Thank you for your support, and I look forward to hearing from you soon.

Best regards, *Vu Khac Hung* ------------------------------------------ Department of Land Administration, Faculty of Geography. VNU University of Science, Vietnam National University, Hanoi 334 Nguyen Trai, Thanh Xuan, Hanoi
