Planet Earth Open Map Data
The data is based on OpenStreetMap and enriched with third party sources. It is organised across eleven themes. Each theme is organised by classes and subclasses. You can drill down from the theme into the classes and from there into subclasses.
- Administrative: This data set contains the polygons for administrative boundaries at different levels. It includes the name of the administrative area, the quadkey, and the geo coordinates.
- Building: Contains the type of building and its surface area.
- Building Detail: Contains additional information on buildings such as building material, construction type, building colour, roof shape and materials used
- Infrastructure: The infrastructure theme contains information on infrastructure such as bridges, towers, communication (cell towers etc), power stations, towers.
- Land: The land theme contains information such as forests, volcanoes, grass, wetland etc.
- Landuse: The landuse theme contains information on the way land is used, e.g. for entertainment, commercial, agriculture etc. purposes.
- Placename: This theme includes named locations from cities, towns, villages etc.
- POI: This theme includes points of interests such as amenities, restaurants, cinemas, schools etc.
- Road: This theme set covers the road network, e.g. motorways, residential streets, cycle ways, national roads etc. It includes the length of road, its usage type, the speed limit and a lot more.
- Transit: This theme covers airports, railways, and buses.
- Water: This theme covers anything related to water such as oceans, rivers, lakes etc.

Use cases and sample Queries
Use cases
Logistics and supply chain management: Road data can be used to analyse transportation routes and optimise delivery schedules.
Urban planning: Road data can be used to analyse the accessibility of different neighbourhoods and identify areas with inadequate transportation infrastructure.
Real estate: Road data can be used to analyse the impact of road proximity and traffic noise on property values.
Market analysis: Administrative boundary data can aid in market analysis by segmenting markets based on geographical regions.
Trade area analysis: The data can be used to define trade areas around existing stores or business locations.
Store location analysis: The data can aid businesses in determining optimal locations for new stores or branch offices
Service coverage analysis: Infrastructure data can be utilised to assess service coverage areas for communication networks.
Real estate market analysis: Building data, particularly square metre footage, is crucial for assessing property values and conducting market analysis.
Location-based marketing: Amenity data can be used for location-based marketing campaigns. By analysing the distribution of amenities, businesses can target their marketing efforts to specific areas based on the presence of relevant amenities.
Retail site selection: Amenity data is valuable for retail site selection.
Property valuation and rental pricing: Amenity data can be used in property valuation and rental pricing analysis.
Sample queries
POI density
We want to analyse which area has the highest density of POIs.
We can use the quadkey in the POI theme to count the number of fast food restaurants per quadkey and then plot them on a map.
For this query we use quadkeys at zoom level 15.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
SELECT substr(quadkey ,0 ,5) ,substr(quadkey ,0 ,6) ,COUNT(9) FROM V_POI WHERE subclass='fast_food' GROUP BY substr(quadkey ,0 ,5) ,substr(quadkey ,0 ,6) ORDER BY COUNT(9) DESC; |
Road network analysis
We will analyse the road network in the London boroughs of Camden and Croyden.
The following query will return the geo coordinates for both of those London boroughs
|
1 2 3 4 5 6 7 |
SELECT A.quadkey ,A.geo_cordinates ,A.NAMES['local'] ,A.ID FROM V_ADMINISTRATIVE A WHERE LOWER(A.NAMES['local']) LIKE '%borough of camden%' OR LOWER(A.NAMES['local']) LIKE '%borough of croydon%'; |
In a next step we can lookup the various classes and subclasses of roads from the ROAD table against the geo coordinates of Camden and Croyden.
We want to compare the types of roads that exist in both boroughs and the length in metres of the road network in each.
