Click any point in Spain and in seconds it is checked against official data: the water underground and whether the rock holds it, flood risk, protected areas, radon, wildfire history and mobile coverage. Free, with no sign-up, you see at once how many things need a closer look. The full answer for one plot, with what to do next and what it costs, is its Dossier.
Catastro, IGME, MITECO, IGN, EEA, Copernicus. The data the public bodies themselves publish, on one map.

Spain in 1956 · a map layer
El Ejido, Almería. In 1956: fields and bare hills around a small village. Today: an unbroken sea of greenhouses, over an aquifer in poor quantitative state (EEA 2022). The 1956 aerial survey can be opened for any point in Spain.
Two real plots, with the figures this site gives. The one that looks better has more red flags.

León gets 60% more rain, and has four red flags to Cuenca’s none. The rock beneath it is practically impermeable, so the ground stores little of that rain. The hills burn: ten fires since 2016, the latest this year. And the municipality has no fibre. Cuenca looks drier on paper and shows none of these flags.
Seventeen layers, four depths, from sky to subsurface. Each from the body that publishes it. Roads, power lines and a few others in the report come from OpenStreetMap, and say so. Nothing scraped from anyone else’s site.
