Discover Land

Know the land before you drive out to see it

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

Seventy years in one scroll

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.

More rain doesn’t mean more water

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.

What exactly is in the database

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.

Who it’s for

Buyers

Rule a plot out from your desk, before the drive and the phone calls.

Agents

Answer on the spot about water, flooding and restrictions, instead of “I’ll get back to you”.

What’s not there yet

  • Plots for sale. The layer exists, but isn’t connected to real listings yet.
  • Rainfall figures are estimates. Our two sources — ERA5-Land and AdapteCCa — differ by 18% at a typical point and by up to 45% in places (our comparison at 212 points, October 2026), partly because they cover different years: 1991–2020 and 1971–2000. Checking them against AEMET’s station records is next; until then we say so rather than hide it.
  • This isn’t a legal check. It tells you what’s worth checking, and saves you weeks on everything that isn’t.

For professionals

Searching plots by criteria, reports for clients, access to the data: that’s what we’re building next. If you work with land in Spain, tell us what you need — it decides what comes first.
