  • Dato Urbano: Barcelona collects, treats, visualizes and distributes data from the Open Data BCN portal

    The Dato Urbano project processes and translates different datasets, from various Spanish localities, homogenizing their treatment in reference to the coordinates’ system, the geographic precision and the distribution format, using the standard open format: GeoJSON. The GitHub platform allows users to see the geographic displays on a map; despite this, the Dato Urbano project has developed adaptive geographic viewers. The project’s purpose is the use of the visualizations in studies about multitemporal evolution. The resulting visualizations of the processing of data obtained through the Open Data BCN portal can be found in a public repository of GitHub, specific to the city of Barcelona. This project’s alive and, so far, 9 datasets of mobility and services have been treated from the Open Data BCN portal.

  • Relation between the location of electric vehicle charging stations and the vehicle park of the city of Barcelona in 2016

    Pol Masclans Abelló, a student of the Bachelor in Industrial Technologies Engineering UPC who has been working on the Open Data BCN service at the IMI (Institut Municipal d’Informàtica) has created a map that relates the charging stations for the electric vehicles in the city of Barcelona with the age of vehicles registered in the city, using the data from the Open Data BCN Portal.

    The interactive map allows you to select different layers, such as the percentage of vehicles with 10+ years old or 20+ years old, grouping by neighborhoods or districts. The aim is to highlight the antiquity or not (according to how it is valued) of the car park of the citizens of Barcelona and to publicize the possibilities that exist for electric vehicle chargers for those who want to acquire a Plug-in vehicle.

    The visualizations has been made using the datasets Barcelona's electric vehicle charging stations and of the Age of car of the city of Barcelona, with data from 2016. In that same year, there were 580,399 cars registered in the City of Barcelona.

  • Visualisation of centres of worship by neighbourhood, linked to the birthplace of Barcelona citizens

    Ferran Pérez Gamonal , a final-year student of audiovisual systems engineering at the UPC School of Telecommunications Engineering, has spent the months prior to his graduation working on the Open Data BCN project at the IMI (Municipal Institute of Information Technology). Using data published on Open Data BCN, he has produced a visual display of data on centres of worship by neighbourhood linked to the birthplace (Catalonia, Spanish state and elsewhere) of Barcelona citizens . This is an interactive map that allows users to select the various layers.

  • Visualisation of Wi-Fi hotspot density

    Iban Tarrés, a geographer and GIS specialist, has produced a map of free Wi-Fi hotspots in Barcelona. This visual display has been created thanks to the information set published on the Open Data BCN portal. The map shows areas with more or less access point density

  • Special dataset visualization "Bicing Stations of the city of Barcelona (Mechanics and electrics)"

    The SIG i Teledetecció (SIGTE) de la Universitat de Girona service has produced a dynamic web map about the activity of the Bicing service in the working day 17th October 2017. The data used are from the dataset Bicing Stations of the city of Barcelona (Mechanics and electric) from the Open Data BCN portal.

    This application, programed in Python, stores in a PostGis database the number of bicycles picked up by the users in every station, minute by minute. This data, along with the temporal variable, is what is used to create the application and to show in an accelerated rate the activity in all the Bicing stations of the city. The source code is available in SIGTE’s GITHUB.

    More information in SIGTE’s blog.

    Also, Lluís Esquerda, a data extraction professional who we have already interviewed in the section “Interviews”, has used data published on Open Data BCN to produce the Barcelona Bicing status map. You can see the number of bikes available at each of the stations spread around the city in real time.

  • Map of innovative initiatives in Barcelona

    The architecture studio 300.000 Km/s has produced the interactive map Geographies of innovation, a visual display of the various innovative initiatives currently under way in Barcelona. The map offers a selection of innovative initiatives, start-ups, companies, research centres and universities produced by Infonomia, and locates them on four different layers that provide information on the socio-demographic situation, the level of services and transport and the type of land use, among other things. That required the use of various Open Data BCN information sets (demographics, levels of income, unemployment and rents) and other data sets from TMB, Flickr, Google Places and the property register.

  • Visualisation of public transport accessibility

    Carlos Carrasco, a researcher from the Cities in Motion centre at the IESE Business School and a member of Eixos.cat, has produced a visual display of open data on public transport accessibility in Barcelona (metro, bus, FGC and Tram) depending on the distance and resident population density in each block. Carrasco used portal data to determine the boundaries and population of the blocks, and the geolocalisation of the public transport stops.

  • Special visualisations of the information set on "accidents dealt with by the police (Guàrdia Urbana) in Barcelona"

    The publication of the information set on accidents dealt with by the police (Guàrdia Urbana) in Barcelona has generated visualisations of high quality by various portal users. The information in the set used for the visualisations allows us to see the different parameters relating to the accidents dealt with by the Guàrdia Urbana in Barcelona.

    Iban Tarrés, a geographer and technician at GIS, has developed an interactive visualization consisting of a cumulative point map in which chronologically each of the interventions carried out by the body of agents of the Urban Guard of the city of Barcelona during the 2016. It gives information of the total, the day strip and the district in which the accidents that we visualize at that moment in the screen have occurred.

    The geographer Víctor León, founder partner of GESTAMBIT, produced various visualisations using his CartoDB profile. We highlight the accumulative heat map, a dynamic map that draws the areas of the city with the most accidents.

    The geographer Juanjo Vidal has also produced a visual display of the portal data set from his CartoDB account. In this case, it is a dynamic, chronological map of the accidents handled by the Guàrdia Urbana in 2014.

    Another portal data visualisation regular is Carlos Carrasco, a researcher at the Cities in Motion centre of the IESE Business School and a Eixos.cat partner. Carrasco has also made various portal visual displays, which he has in his Twitter profile and here we highlight the map showing the total number of accidents in 2014.

    Diego Villuendas is yet another portal user who has produced a visual display of the data set using CartoDB technology (here is his profile). In his case, the map uses two layers that represent the accidents according to the time of day they occurred and the day of the week they took place.

    The people of TeamUNO (you can follow them on their Twitter profile), which came out of the UB postgraduate course on Data Science and Big Data, have come up with the first visualisation of the trend in accidents handled by the Guàrdia Urbana in Barcelona between 2010 and 2014. The one we highlight corresponds to the time spread, by day of the week and month, in 2014.

  • “Movement vs. density”, visualisation of the “atNight” project

    The 300.000 Km/s studio carried out the atNight project to reflect on the features that define Barcelona’s nightscape. One of the mappings that came out of this initiative is the one below, entitled “Movement vs. Density”, which seeks to illustrate how road space and private space correspond. To achieve that, a layer generated from the geolocalised routes of part of Barcelona’s taxi fleet is contrasted with the population density by block taken from the Open Data BCN portal.

  • Visualisation of population density at a block level, by Carlos Carrasco

    Carlos Carrasco, a researcher from the Cities in Motion centre at the IESE Business School and a partner at Eixos.cat has created a visual display of the population density at block level in Barcelona, based on data supplied by the city’s Open Data portal. Carrasco, a data visualisation enthusiast, has produced up to four different visualisations of this concept: with and without the street guide included, and with and without areas of less density. The specific visualisation we offer in this space does contain the city street guide but does not include the minimum values, which take up a lot of space on the map and provide little information of any relevance.

  • Visualisation of city roadside trees by Juanjo Vidal

    The geographer Juanjo Vidal has produced a visual display of roadside trees in Barcelona based on data published on the city’s Open Data portal, which has more than 170,000 entries. It should be borne in mind that the roadside tree concept corresponds to trees by the side of roads. Therefore, it does not include either park or area trees, as these are treated differently.
