Dear Sir/Madam,

I hope you are doing well.

I would like to clarify the registration conference fee category. I am the corresponding author of two research papers:

1. An Integrated Geoinformatics and Machine Learning Framework for UAV-Based Forest Biomass and Carbon Assessment (First author: Thinnakon Angkahad)
2. Satellite-Based PM2.5 Estimation Using Ensemble and Boosting Machine Learning Techniques (First author: Piyatida Awichin)

Both Thinnakon Angkahad and Piyatida Awichin are Ph.D. students at Mahasarakham University, Thailand. In this case, they will proceed with the payment under the international student category.

Please kindly confirm if this is correct or if any additional documents are required.

Thank you very much for your kind support and consideration.

Best regards,
Assoc.Prof.Dr. Teerawong Laosuwan
