How to find the cadastral data of a property if you know the location: the reverse process

You have identified a property on Google Maps — perhaps a plot of land, an abandoned building, or your neighbor's property — and you want to find out which sheet and cadastral parcel it corresponds to? In this guide, we show you how to take the reverse route: starting from a location on the map and tracing back to the cadastral data, without needing to access the Agenzia delle Entrate portal.

Why you might need to find cadastral data from a location

There are dozens of situations where you know where a property is located, but you don’t know the cadastral references. Here are the most common:

• You want information about a property near yours — the adjacent land, the building across the street, an apparently abandoned lot
• You found an interesting property while walking — and you want to check the cadastral status before contacting the owner
• You are considering an investment — and you want to cross-reference the location with the official data to then request a cadastral report
• You need to verify the boundaries of a property — and you need to know which parcels border yours
• You are a professional (surveyor, lawyer, real estate agent) and during a site visit, you want to quickly identify the cadastral references

In all these cases, the traditional route would be long and cumbersome: you would need to know at least the exact address, access the Sister portal of the Agenzia delle Entrate, perform a search by address (often inaccurate), and pay for each cadastral report. Or you could use our free tool.

The traditional route: why it’s complicated

To find the cadastral data of a property starting from the location, you would normally need to:

• Identify the exact address of the property (not always easy, especially for land or rural areas)
• Access the Geoportale Cartografico Catastale of the Agenzia delle Entrate
• Navigate the map (often slow and unintuitive) until you find the area
• Click on the parcel to read the sheet and parcel number
• Or request a report by address on Sister (for a fee)

The main problem? The official cadastral map is not overlaid on a modern map: you will only see lines and numbers on a white background, without street references or recognizable buildings. Navigating is difficult, especially in rural or peripheral areas.

How to find cadastral data with Aste Florio's Cadastral Tool

The Cadastral Tool of Aste Florio solves this problem by overlaying the official cadastral layer directly on Google Maps. This means you can navigate the map as you normally do — with roads, buildings, satellite view — and at the same time see the boundaries and numbers of the cadastral parcels.

There are two methods to find the cadastral data of a property starting from the location.

Method 1: Click directly on the map

This is the most intuitive method and works perfectly when you know approximately where the property is located.

Step 1 — Open the tool and navigate to the area

Go to asteflorio.it/catasto and use the map to move to the area of interest. You can search for a city or an address in the search bar, or navigate manually with zooming and dragging.

Step 2 — Activate the cadastral layer

Make sure the cadastral layer is active: you will see the parcel boundaries appear on the map as colored lines. As you zoom in, the sheet and parcel numbers will also appear directly on the map.

Step 3 — Click on the property

When you have located the property or land you are interested in, click directly on the parcel. The tool will immediately show:

• Cadastral municipality — the code of the municipality where the parcel is located
• Sheet — the number of the cadastral sheet
• Parcel — the identifying number of the parcel
• GPS Coordinates — latitude and longitude of the clicked point

The selected parcel is highlighted with an outline for easy visual identification.

Step 4 — Note or copy the results

With the sheet and parcel in hand, you can proceed to request a complete cadastral report (which will tell you the owner, cadastral income, category, area, and all other data) or use this information for your research.

Method 2: Paste a Google Maps link

This method is perfect when you have already identified the location on Google Maps and want to quickly discover the cadastral data without having to navigate again.

Step 1 — Copy the link from Google Maps

On Google Maps, locate the property and copy the link from the browser's address bar, or use the "Share" function to get the link. The link will contain the GPS coordinates of the location.

Step 2 — Paste in the coordinates field

In the Cadastral Tool, you will find a dedicated field to paste coordinates or Google Maps link. Paste the link and press Enter: the tool will automatically extract the coordinates and center the map on that exact point.

Step 3 — Read the cadastral data

With the cadastral layer active, you will immediately see the corresponding parcel for the point indicated by the link. Click on the parcel to obtain all the cadastral data.

How to read the results

When you click on a parcel, the tool shows you a series of cadastral information. Here’s how to interpret them:

• Cadastral municipality — this is the code with which the Agenzia delle Entrate identifies the territory. In many cases, it coincides with the name of the administrative municipality, but be careful: after mergers or municipal consolidations, the cadastral code may be different
• Sheet — each municipality is divided into cadastral sheets. The sheet is a "page" of the cadastral map that covers a portion of territory
• Parcel — within the sheet, each plot of land or building has a unique number. This is the main data you need to request a report

With these three data points (municipality + sheet + parcel), you can uniquely identify any property in Italy and proceed with reports, verifications, or cadastral practices.

Practical use cases

Let’s look at some real scenarios where reverse searching for cadastral data proves to be very useful:

The neighbor's land

You are renovating your house and want to know who owns the abandoned land next to yours. You see it from your window, you know exactly where it is, but you have no idea about the sheet and parcel. With the tool, you click on the land from the satellite view and in a second you have the cadastral data to request a report and find out the owner.

An abandoned building to buy at auction

You have noticed an abandoned building in an area that interests you and want to know if it is up for auction or could be purchased. The first step is to identify the sheet and parcel to search for the property in the judicial auction portals or at the cadastral office. With the tool, you identify it in a few seconds.

Verify agricultural land

You have been offered the purchase of an agricultural land and want to verify that the boundaries declared by the seller correspond to the cadastral ones. Overlay the cadastral layer on the satellite view and visually compare: if the boundaries do not match, it’s time to investigate further.

Professional site visit

You are a surveyor on a site visit and the client asks you on the spot for the cadastral data of a property you are looking at together. Open the tool from your phone, point the map to the location, and in no time you have the sheet and parcel, without having to return to the office to consult the Agenzia delle Entrate portal.

Extra tips for better results

Here are some tips to make the most of the tool in reverse searching:

• Always use satellite view — it’s much easier to recognize buildings and land compared to the classic street map
• Zoom to the maximum level — the cadastral layer becomes more detailed and readable as you zoom in. At the level of a single parcel, you will clearly see all the numbers
• Adjust the transparency — use the slider to find the right balance between the underlying map and the overlaid cadastral layer
• Combine with direct search — once you find the sheet and parcel from the map, you can use them in the search field to highlight exactly that parcel and confirm that it is the right one
• Check adjacent parcels — sometimes a property extends over multiple parcels. Click on those surrounding it to get the complete picture

In the end, the transition from "I see a property on Google Maps" to "I know exactly the sheet and parcel" doesn’t have to be complicated. With the Cadastral Tool of Aste Florio, you just need to open the map, click on the property, and you have everything — free, no registration, directly from your phone or computer.

Whether you use it for personal curiosity, for work, or to evaluate a purchase, it’s one of those tools that once you try, you wonder how you managed without it before.
