A high resolution map of tree canopy cover for Greater London was produced from aerial imagery using machine learning techniques. The map was produced by Breadboard Labs in collaboration with the Greater London Authority as part of a Breadboard Lab’s European Space Agency funded project, Curio Canopy .  The algorithms and machine learning based techniques used to produce...

Two Google Street View cars, equipped with reference-type air quality monitors, are measuring air pollution over approximately 600 eight-hour shifts between autumn 2018 and autumn 2019. The cars use fast-response, research-grade instruments to precisely measure pollution concentrations approximately every 1-10 seconds. Pollutants measured include black carbon (BC), CO₂, NO, NO₂, O3, PM2.5 (and other PM size ranges) on a variety...

(Minor update on 07/11/2019, following feedback from Hillingdon. Hillingdon Pump Lane Focus Area has been included in the Hayes Focus Areas) According to the LAEI 2016, there are 183 Air Quality Focus Areas in London.

These ward level well being scores present a combined measure of well-being indicators of the resident population based on 12 different indicators. Where possible each indicator score is compared with the England and Wales average, which is zero. Scores over 0 indicate a higher probability that the population on average will experience better well-being according to these measures. Users can adjust...

The Green Infrastructure Focus Map is a new tool and evidence base to help London’s decision-makers identify where green infrastructure improvements and investments might be best targeted, and what kind of interventions might be most useful for the needs of a specific area. The Green Infrastructure Focus Map can help: identify where there is more need or less...

The Mayor has a role to play in leading, shaping and responding to changes in London through the work of the GLA group. Inclusive London: the Mayor's equality, diversity and inclusion strategy sets out how he will help address the inequalities, barriers and discrimination experienced by groups protected by the Equality Act 2010, as well as wider issues. These include...

Following the release of the latest London Atmospheric Emissions Inventory (LAEI) 2016, additional data has been produced at Borough level, to assist London boroughs with their LLAQM (London Local Air Quality Management) duties. The data below is based on the NOx, NO2, PM10 and PM2.5 emissions and ground level concentrations already published as part of the LAEI 2016. It includes the following datasets, which...

Overview An updated spatial data set for existing green roofs has been produced for London's Central Activities Zone (CAZ) using 2015 aerial imagery. The CAZ makes up around two per cent of London's total area. Method ArcMap GIS software was used to map green roofs installations. The aerial imagery was loaded into the software in true colour (RGB) and infrared (IR) composites, along...

A heatwave refers to a prolonged period of unusually hot weather. While there is no standard definition of a heatwave in England, the Met Office generally uses the World Meteorological Organization definition of a heatwave, which is "when the daily maximum temperature of more than five consecutive days exceeds the average maximum temperature by 5°C, the normal period being 1961-1990"....

This dataset provides locations of open spaces in London identified by research and data analysis as Privately Owned Public Spaces (POPS), based on the definition below and available data in 2017. This is not a fully comprehensive dataset and is based on multiple sources of information. Subsequent versions will provide updates as more information becomes available. Read more here. The dataset...
