About Jersey digital mapping data
The Jersey digital mapping data is based on reliable data and covers the Island in details, its coastline and reefs.
It's similar to other online maps but it's more accurate and up to date.
You can use and view it in many different ways and it is essential for various users, including:
- architects, to submit site plans
- delivery companies, to swiftly locate delivery addresses
- lawyers and advocates, to identify property details and record information associated with the property
- online business, to add location information to their systems and solutions
- anyone working on projects, to inform decisions
- the public, to see and view Jersey information
The data is continually updated and is available to commercial users through
our commercial business partners and the public through our
mapping gallery.
Core data sets
This consists of subgroups of data layers, each fully controllable whilst remaining accurately aligned. They are designed to be compatible with online services and most Geographic Information Service (GIS) software packages and Computer Aided Design (CAD) systems.
The data sets include:
- land parcels: polygons showing the extent of individual land features. The data set is attributed with unique identifiers and geometric information together with the area and classification
- roads: polygons showing the extent of the Island's road network. Each segment is attributed with the official road name, the administering authority and the area of the segment. Footpaths and driveways are also depicted in the roads layer
- buildings: building polygons are fully attributed and classified by type
- parishes: polygons of the parishes are depicted to their high water extent. A data set of the vingtaines is also included
- water: streams, ponds and quarries are identified
- contours: a layer of Island's contours at 5 metre intervals
- land supplementary and road supplementary data detail such as walls, hedges and cliff paths and text
Aerial photographs
A bird’s-eye view photo of the whole Island is taken each year.
It's made from hundreds of smaller aerial photographs and a ground resolution of 10 centimetre for each pixel. The photos provide a seamless and accurate full colour overlay to the core mapping data set.
Photo prints of Jersey or selected areas of the Island are also available.
The model provides easy access to a 3D visual representation of the whole of Jersey.
It has been created using aerial photography and ground level photo surveys of:
- the terrain
- buildings with roof textures (whole Island)
- buildings with roof textures and façade textures (St Helier only)
- vegetation canopy
- walls and fences
The 3D data is held in both
Drawing Exchange Format (DXF) and Sketchup formats (buildings).

Address data (Jersey Land and property Gazetteer)
The Jersey Land and Property Gazetteer is the central corporate address database for the Government of Jersey.
It derives from the Jersey Land and Property Index (JLPI) which is updated daily from authoritative sources. JLPI, and the derived Corporate Address File (CAF), contains address information for the public and private sectors of over 90,000 address points including:
- private property addresses
- address of registered businesses
- field numbers
- streets
- slipways
- reservoirs
- schools
- churches
- places of interest, dolmens
Can't find an address
If the property you're looking for is a new build, the address might not have been added to our database yet.
If the property isn't new and you can't find the address, check:
- your spelling
- if the address is a building name. We may be unfamiliar with the name so try searching for the street number only
If you still can't find the address or the address has an error in it, email
addresses@gov.je.
For errors, please include the address we currently hold, and the update required. For addresses that can't be found please include the street and any buildings or landmarks near to help us locate it
Changing your house name
You can apply to change the name of the property you own. You need to contact Jersey Post first.
Jersey Post will be able to process the name change if there isn't an existing property with that name in the same parish or post code area.
