C.A. León Sánchez

C.A. León Sánchez is a researcher at Delft University of Technology's Faculty of Architecture and the Built Environment specializing in Urban Data Science. He recently completed his PhD dissertation on semantic 3D city models for urban energy applications in the Netherlands, establishing his expertise in geospatial analysis and sustainable urban systems.

His research integrates semantic 3D city modeling with energy engineering to advance solar potential computation and urban energy planning. Key contributions include developing open-source geospatial tools like the 3DCityDB-Tools Plug-in for QGIS and high-resolution solar modeling frameworks that leverage CityGML standards for urban environments.

León Sánchez's publication trends reveal a strong focus on practical urban applications of geospatial technologies, with significant work in solar energy optimization and cross-disciplinary extensions into agricultural remote sensing. His methodologies bridge semantic web technologies, drone-based data acquisition, and computational modeling for sustainable city development.

His scientific recognition includes:

• Best Young Researcher Award at the 9th International Smart Data and Smart Cities conference 2025

As an active contributor to the TU Delft 3D geoinformation group (tudelft3d), he maintains critical open-source infrastructure including the 3DCityDB-Tools ecosystem and CityGML-based energy modeling testbeds, fostering international collaboration in urban data science.
