Dear GIS-IDEAS 2026 Secretariat,

Thank you very much for sending the updated conference program.

I noticed that the title of my presentation is incorrectly listed in the program. My presentation details are:

*Session 2: Web-GIS, Spatial Computing, and Area Informatics* *Conference Room:* Thuan Thanh (3rd floor, C12 Building) *Time:* 11:00–11:20 *Speaker:* Sittichai Choosumrong

The program currently lists the title as:

*“Spatio-Temporal Traffic Accident Risk Analysis in Regional Transit Hubs: A Graph Neural Network Approach with H3 Indexing in Phitsanulok, Thailand”*

However, the correct title should be:

*“An Inteligent IoT-Based Poultry Housing System for Real-Time Environmental Control and Precision Management”*

I would be grateful if you could kindly correct the title in the conference program.

Thank you very much for your assistance.

Best regards, *Assoc. Prof. Dr. Sittichai Choosumrong* ------------------------- Ph.D (Creative Cities): Osaka City University Division of GIS and GISci. Dept. of Natural Resources & Environment; Faculty of Agriculture Natural Resources and Environment, Naresuan University, 65000 Office: +66 55 96 2756 Fax: +66 55 96 2750 Mobile: +66 91 767 2963 OSGeo charter member 2014, Thailand. https://wiki.osgeo.org/wiki/Sittichai_choosumrong https://wiki.osgeo.org/wiki/Sittichai_choosumrong ■□■□■□■□■□■□■□■□■

Dear Colleagues, We are now less than one week away from the GIS-IDEAS International Scientific Conference. Please find attached the latest updated conference program. We kindly ask you to refer to the program when preparing your presentations. In addition to the main conference, which will take place on September 25–26, two workshops will be held on September 24. The workshops will be conducted by Prof. Maria Antonia Brovelli from Politecnico di Milano, Quang Huy Nguyen, PhD Candidate at Politecnico di Milano, and Dr. Pham Thi Mai Thy from the Vietnam National Space Center (VNSC). Detailed information about the instructors was provided in my previous email. We are still accepting registrations for both workshops. Registration will close once the number of participants reaches 20 or on September 20, 2026, whichever comes first. To ensure that the workshops run smoothly, the instructors kindly ask all participants to prepare their laptops and install the required software in advance. Please find the detailed requirements in the attached file, *Note.pdf*. We very much look forward to welcoming you to GIS-IDEAS 2026 and to seeing you in Hanoi. Best regards, GIS-IDEAS 2026 Secretariat

Dear Conference Secretary,

I am writing regarding our presentation entitled “Pavement Crack Detection and Segmentation Using Lightweight Deep Learning Models,” scheduled from 14:50 to 15:10 in Session 6.1: Big Data Analytics and Predictive Modelling in Geoscience.

Unfortunately, due to unforeseen circumstances, we are unable to attend the conference onsite to deliver the oral presentation in person.

Therefore, we would like to present our research in poster format instead of the scheduled onsite oral presentation.

We sincerely apologize for any inconvenience this may cause and greatly appreciate your understanding and consideration.

Thank you very much for your support.
