Which building rooftops show stronger modeled solar potential?
The demonstration aligns a USGS digital surface model with OpenStreetMap building footprints. Rooftops are isolated before modeling radiation with slope, orientation and shading effects.
Zonal summaries translate the modeled surface into building-level measures and potential classes. Monthly radiation patterns add a seasonal view alongside the overall comparison.

From question to analysis
Data and inputs
- A digital surface model
- Building footprints in an aligned coordinate system
- A modeling year and solar-radiation parameters
Analysis described in the video
- Check surface-model and building-footprint alignment.
- Isolate rooftops and calculate radiation for the selected period.
- Summarize radiation and rooftop area for each building.
- Compare potential classes and inspect monthly patterns.
Understand the output
Outputs described
- Building-level radiation and rooftop-area summaries
- Solar-potential classes and seasonal comparisons
What to review
- Review surface-model resolution, rooftop geometry and shadow assumptions.
- Modeled radiation is a screening input; installation feasibility needs further assessment.
