About Me

I am Tang Kai (唐凯), a Ph.D. candidate in Cartography and Geographic Information Systems at Beijing Normal University (2022.09-2026.06), advised by Prof. Jin Chen. My research focuses on remote sensing image processing and applications, change detection, on-orbit computing, and artificial intelligence for Earth observation.

My research experience began with Remote Sensing Science and Technology during my undergraduate study, followed by master's research on radiometric quality improvement and physical parameter retrieval for China's Fengyun meteorological satellites. During my Ph.D. study, I have focused on deep learning-based change detection and multimodal data fusion, with an emphasis on integrating remote sensing physics and geoscientific knowledge into AI models.

I am always open to collaboration and academic exchange with researchers and practitioners interested in remote sensing, GeoAI, change detection, agricultural intelligence, data fusion, and Earth observation applications.

Research Interests

  • Change detection: high-resolution single/bi-temporal change detection, medium-resolution time-series change detection, and near-real-time anomaly discovery.
  • Data fusion: optical-SAR fusion, asynchronous time-series reconstruction, and multimodal Earth observation learning.
  • Agricultural remote sensing: crop mapping, sowing and harvest date detection, yield estimation.

News

  • 2026.03 A Paper on estimation of crop sowing dates was accepted by The Crop Journal (JCR Q1 TOP).
  • 2026.03 ClearSCD has been selected as an ESI Highly Cited Paper.
  • 2026.02 A Paper on crop mapping models was accepted by ISPRS Journal of Photogrammetry and Remote Sensing and released with [Code].
  • 2026.01 DreamCD was accepted by International Journal of Applied Earth Observation and Geoinformation and released with [Code] and [Dataset].
  • 2026.01 Shield was accepted by Journal of Remote Sensing and released with [Code].
