ISPRS/ISDE Conference on Geo-digitalization for Sustainable Development Goals

Innovation and Future Trends in Geo-digitalization for Sustainable Development

02-04 Dec 2025
Nairobi,Kenya

Background of the Event

Geo-digitalization is a key transformative approach for advancing the Sustainable Development Goals (SDGs). By harnessing the power of geospatial data and digital technologies, geo-digitization provides precise data-driven decision support and enables a holistic understanding of complex global challenges. Geo-digitization helps to improve data accuracy and accessibility, monitor changes to our environmental, increase risk management capabilities, support infrastructural development and urban planning, and promote inclusivity. Thus, as the world strives to achieve the SDGs by 2030, embracing geo-digitalization will be crucial in ensuring sustainable, inclusive and resilient development for all.

The ISPRS/ISDE Conference on geo-digitization will bring together experts, practitioners, researchers and people of like mind to share experiences and best practices for enhancing geo-digitization across the globe.
