This page gives guidance on the definition of land use and how it should be mapped in OpenStreetMap.

Land use, as the name suggests, describes what an area of land is used for e.g. housing, commercial activities, farming, education, leisure, etc.

Land use is distinct from 'Landcover' - land cover describes the physical thing/surface covering the land. The two concepts are complementary and can be used together. The land use might be 'military' but the land cover might be 'heathland' or the land use might be 'leisure' but the land cover might be 'grass'.

Some feature tags imply both a landuse and a landcover. For example, landuse=vineyard defines an agricultural area covered in grape vines used to produce grapes.

Due to the way that OpenStreetMap has evolved over time, land use in OpenStreetMap is mapped with a variety of tags including landuse=*, amenity=*, leisure=*, and tourism=*. See the table below for further examples.

Generally areas are tagged with one main land use and they do not usually not overlap. But in some cases mappers give more detail within a larger area. For example a leisure=playground tag may be used on a playground that is contained within a particular landuse=residential area.

How to map land use

Different techniques for mapping land use exist in OpenStreetMap.

Mapping as nodes

Land use by its nature is an area, but if it is not feasible to map features as an area it is OK to map land use as node and update it to area once possible. It is typically because both aerial and GPS traces of shape are unavailable. For example it is preferable to map landuse=cemetery as node rather than not mapping it at all.

Note that some other land uses like landuse=railway are almost completely useless as nodes and not worth mapping in this form.

Mapping large uninterrupted areas

When first mapping a place many mappers draw large uninterrupted shapes around areas that are assumed to have a single land use (this technique is suggested on LearnOSM.org). Typically these areas might be tagged with quite broad uses such as landuse=commercial, landuse=industrial or landuse=residential (where this is discussed further).

While this is useful as a starting point, it quickly becomes necessary to break these areas down to add more detail to the map - for example to add schools, health facilities, parks etc. into broad areas initially outlined as residential.

Mapping land use in more detail

There are two main approaches to mapping land use in more detail. They differ primarily in how they treat land dedicated to the public highway or other transport networks.

1. Mapping the reality on the ground

The key to this method is to strictly draw the boundary around each land use following its boundary in the real world. For example to map the land use of a school draw the edge of the shape following the boundary of the land that is used by/available to the school; to map a residential area include land that actually belongs to the houses and their gardens/private driveways.

Land that is dedicated to the public highway (both the carriageway and the pavement/verge) is not land that is available for other uses i.e. you can't build a house on it, and so it shouldn't be mapped as such. While a landuse=highway tag has been proposed it is not currently in use and so land used as public highway should simply be left blank.

This method largely keeps the highway network lines and land use polygons separate making subsequent editing simpler and more accurate. In urban areas the result will be 'islands' of land use polygons in between the lines of the highway network.

2. Using highway centrelines

Another approach that some mappers have taken is to either draw land use polygons that extend over the public highway sharing nodes with highway centrelines, or to fragment the highway network and create land use areas from relations of the fragments. While this results in less drawn geometry subsequent editing is more complicated. This increases the risk of damaging not only the land use areas but also the highway network. It is also less accurate, extending adjoining land uses over land that is dedicated to the public highway.

How to tag land use

Note that there is an ongoing discussion on how to tag some types of land use. See Proposed features/highway and Forest

Table of some existing land use tags

The following table is a 'work in progress'. Click on the symbols in the headings to sort the tables in different ways.

Purpose Category Comment
Aerodrome (airport) Transportation aeroway=aerodrome or landuse=military + military=airfield
Allotments Agriculture landuse=allotments
Aquaculture Agriculture landuse=aquaculture
Basin Water landuse=basin - a man made water control or storage device. Used only for the (intermittently) water-covered area
Beach Natural or Developed natural=beach. leisure=beach_resort Beach is landform alongside a body of water which consists of loose particles.
Brownfield Developed landuse=brownfield - land scheduled for new development which was previously used for other purposes.
Cemetery Developed or Natural landuse=cemetery or amenity=grave_yard
College Developed amenity=college - an institue of Further Education (e.g. Junior College or Continuing Education)
Commercial Developed landuse=commercial - offices and non-retail services
Construction Developed landuse=construction - area currently under construction
Fallow Agriculture No specific tag has been documented. Fallow land often indicates that the land is used for agriculture see landuse=farmland or landuse=meadow.
Farm land Agriculture landuse=farmland and landuse=farmyard
Forestry Agriculture Some think there is no specific tag. landuse=forest is used by some for areas that are used to obtain forest products, by others simply for any tree-covered areas. See Forest for related tags and discussion of the situation.
Garden Leisure leisure=garden
Garages Developed landuse=garages (often within landuse=residential).
Graveyard Developed or Natural landuse=cemetery or amenity=grave_yard
Grazing Agriculture landuse=meadow for pasture used for grazing animals or for hay or silage for animals. There is no specific tag for low-intensity rangeland. For other areas of grass see Landcover.
Greenfield Other landuse=greenfield is used to describe land that has been scheduled for some sort of construction.
Greenhouses Agriculture landuse=greenhouse_horticulture
Highways Transportation No approved tag at present, but there is a proposal to use landuse=highway for the purpose.
Hospital Developed amenity=hospital
Industrial Developed landuse=industrial
Landfill Developed landuse=landfill
Meadow Agriculture landuse=meadow - also used for pastures
Military Military landuse=military, and optionally also military=naval_base, military=range, military=danger_area or military=barracks. For military aerodrome use aeroway=aerodrome and aerodrome=military or military=airfield.
Mine (open pit) Developed landuse=quarry - used for quarries and open pit mines
National Park Leisure boundary=national_park. See also boundary=protected_area
Nature reserve Leisure leisure=nature_reserve. See also boundary=protected_area and the discussion about terms (International consistency)

Challenges mapping land use

key:landuse values not used to indicate land use in all cases

Land use tags have been evolving over time and haven't always been used consistently. As an example landuse=forest has been used to indicate any tree-covered area rather than to indicate areas specifically used for forestry and the production of timber.

Purpose Comment
Grass landuse=grass does not always describe a land use, it often describes a Landcover.
Forest landuse=forest is not clearly distinguished from natural=wood as both usually are areas covered with trees. Determining if the trees are actually used and in what way is difficult. See Forest for more details.

National Land Use Database vs Openstreetmap

The following table compares land use classes from the UK National Land Use Database (NLUD) in Great Britain, and the commonly used land use tags on OpenStreetMap (mostly values of the key landuse=*).

If a tag sometimes describes more than one land use category, it is followed by an asterisk (*).

In many cases, a sub-category on the NLUD will be represented by several different features in Openstreetmap (for example, community services). In other cases, several categories may used the same tag (for example, landuse=industrial).
