Why it surfaced
This is a focused civic tool with unusually clear limits: it uses OSM, MaStR, and NRW LoD2 roof data to produce a short list of plausible sites, rather than a noisy heatmap. Its Wuppertal pilot reports 15 desk-checked locations, no automated outreach, and a human decision about which leads merit contact.
