Thanks for sharing this! The use of deep neural network regression, especially the enhanced U-net architecture, for generating high-resolution nDSMs from Sentinel-2 imagery is quite impressive—especially considering the challenge of working with lower-res SAR data.
For those exploring practical implementations, the integration with ArcGIS.learn really opens up doors for custom training and deployment. Definitely worth checking out for remote sensing professionals.
At Community Improvement Group, we're actively exploring AI-driven geospatial solutions, and advancements like this align well with our work in digital terrain modeling and remote sensing analysis.
