Data sources

SpotoSpot is built on work other people published. Here is every source behind what you see, and the licence it is credited under.

Maps

Every map on SpotoSpot is drawn from open data. Street geometry, place names, building footprints and the routes between your stops all trace back to OpenStreetMap contributors.

Administrative boundaries in the basemap are drawn from data published by OpenStreetMap and Natural Earth via Protomaps, and do not imply endorsement of any territorial claim.

Street trees

At street zoom the map draws individual trees: position, height, crown size and the shape of the canopy. Every one comes from the city that inventoried it, so the credit is owed per city rather than per layer, and what each city measures differs: some survey every tree's height, others record only the trunk and leave the rest to be inferred.

Street trees in New York City: each tree's position, species and trunk diameter, from the Parks Department's forestry records

Street and park trees in Seattle: each tree's position, species and trunk diameter, combined from the Department of Transportation's and Parks and Recreation's inventories

Tokyo Metropolitan Government, Bureau of Construction
Street trees along Tokyo's metropolitan roads: each tree's position, species, height, crown spread and trunk girth. The only source here that measures every tree's height. Metropolitan roads only, so the main avenues are planted and the side streets between them are not

Ville de Paris
Trees in Paris: each tree's position, genus, species, cultivar, height and trunk girth. Not only streets: the city's gardens and cemeteries are inventoried too, so Père Lachaise and the Bois de Boulogne are planted rather than bare

DC Open Data / District Department of Transportation
Street trees in Washington, DC: each tree's position, species, height and crown size. DDOT's LiDAR crown survey is why DC's are the only trees drawn at a measured height rather than one modelled from the trunk

City of Vancouver
Public trees in Vancouver: each tree's position, species, trunk diameter and the city's own height measurement. The first city here to publish heights, and the first whose park trees are included alongside the street ones

Trees across the canton of Geneva: each tree's position, Latin name, height and the canton's own measurement of its crown width. One of only two sources here that measures crowns rather than inferring them
