Enhancing Live Weather Monitoring with MQTT and Chart.js
Introduction Viewing real-time data from a personal weather station such as a Davis Vantage Pro, a Tempest, or an EcoWhitt device can be complex. However, the majority of systems that…

At the end of each year (normally between Christmas and New Year), there’s a lot to tidyup across Bike Share Map (BSM), the Meddin Bike-Sharing World Map (BSWM) and the UK Shared Micromobility Dashboard. This year, I’m aiming to document all the changes needed, roughly around the time that I make the changes. Monday:

You may be wondering why it’s been so quiet on Bikesharp, the last couple of years… well the reason is that I have been a data journalist on this topic for Zag Daily, an online magazine focusing on shared electric micromobility, particularly in Europe and especially in the UK. So I’ve been writing about the […]

It’s very hot in London today, and tomorrow. It’s best not to be out and about at all, but if you need to be in London, there are some places which may be cooler than others – public venues with air conditioning, some tubes/trains (if…

This attractive map of the housing and infrastructure history of Walthamstow and Leyton in north-east London has been created by Scott Davies. Scott used QGIS and OpenStreetMap data to create an attractive, vintage-style basemap and then shaded residential areas with different colours indicating when each block was developed. Older areas are shown in blues, while […]

The Greater London Authority has published a data map, showing the locations within London where tree canopies can be seen from overhead. There are about as many trees as people in London, and 21% of the capital’s land area is covered by them. This is an impressive number – this must make London one of […]

Air pollution has long been a problem in London, and the current mayor has identified pollution as one of his major goals to highlight and tackle polluion, and improve the capital’s air quality during his time in charge. This map, of the modelled 2020 annual pollution levels of NO2, has been produced by Parallel, using […]

The Best Commuter Hotspots
Tired of London? Samuel Johnson said you are then tired of life. But sometimes, there are attractions in living outside the capital, while continuing to work in the centre. Such as a nice big garden, and being away from the “urban heat island” that makes London hotter than the surrounding regions. To do that, you […]

London’s been sweltering under a heatwave for the last couple of weeks. Mapping London co-creator Dr James Cheshire has created this map from the latest (29 JUne) Landsat 8 thermal imagery of the capital. ExCeL is a particular hotspot – its large, flat, metallic roof was showing a temperature of 38°C, having been baked by […]

Here’s a fascinating data map of ground deformation (subsidence, upswelling) in central London, based on data from 2011-2017 and recalibrated to show the average annual change – be it rising (blue = 2mm/year upwards) or sinking (red = 2mm/year downwards). The data was obtained from 150 remote sensing images captured by TerraSAR-X and other InSAR […]

It’s a typical August day in London today, with the rain falling pretty heavily and at least one tube station closed due to flooding. London’s greatest long-term flooding threat, though, is from isothermal expansion of the world’s water (i.e. it needs slightly more space as it heats) due to climate change. The above map was […]

Speed Limit Map
TfL have published a “London Digital Speed Limit Map“, showing speed limits for cars on a map of London’s public roads, for the last few years. It is updated annually, and TfL have just released a 2017 version. The map is published alongside data supplied to digital mapping data providers, so that they can program […]

Traffic Counts
My latest London data visualisation crunches an interesting dataset from the Department of Transport. The data is available across England, although I’ve chosen London in particular because of its more interesting (i.e. not just car dominated) traffic mix. I’ve also focused on just the data for 8am to 9am, to examine the height of the […]

London’s Street Trees
Following a data release of Southwark’s publically maintained trees a couple of years back, the Greater London Authority recently published a map which shows street trees (trees along roads and public paths, and trees in public open spaces, such as small parks and other minor green areas). Each borough has its own tree database and […]

As it’s been a while since I last posted, I thought I’d put up something I prepared for a Royal Society Smart Cities and Transportation workshop next week. I’ve focussed on data collected at the individual-level, and the opportunities the data present for better understanding cities, and the challenges the maximisation of these resources face. There are no …
