Urban Solar Irradiation at Ground Level for Rennes Métropole

<p>Conducting a comprehensive assessment of solar irradiation at the pedestrian scale across all ground surfaces in a city can help identify cooler routes for pedestrian navigation and prepare the city for potential overheating issues by pinpointing overexposed areas. This dataset results from an effective method for conducting such assessments within a Geographic Information System (GIS) at a metric resolution across regions, such as Rennes M&eacute;tropole in France, which spans over 700&thinsp;km&sup2;. This method has been detailed in the article entitled "Efficient matrix algebra encoding for urban solar irradiation simulation: fine-grid ground-level estimation with vector data" (doi: <a href="https://dx.doi.org/10.1080/13658816.2024.2425339" target="_blank" rel="noopener">10.1080/13658816.2024.2425339</a>). Please note that these simulation results only account for the effects of building shading. The shading provided by trees, street furniture, or the terrain model is not considered at all.</p>
