ISG-ISRS National Symposium 2025 invites researchers, professionals, and students to submit original contributions that advance the theory, methods, and applications of geospatial technology. The symposium welcomes high-quality papers addressing a broad range of topics, including but not limited to: AI/ML/DL and big data analytics in remote sensing, hyperspectral, multispectral and SAR imaging, data fusion, UAV-based observations, 3D city modelling, GeoBIM, real-time data analytics, environmental monitoring, disaster risk reduction, land use and land cover change, urban planning, and geospatial data fusion to mention a few. Submissions are encouraged from both academic and applied research perspectives, with a special emphasis on interdisciplinary approaches that leverage remote sensing and geospatial technology for sustainable development and bringing innovative solutions for management and planning. Accepted papers will be presented in oral and poster sessions and published in the official symposium proceedings. ISG-ISRS NS 2025 particularly encourages participation from practitioners and users of geomatics, reflecting their commitment for use of geospatial technology and innovation in Earth observation sciences and applications.
