Help to use the Mobiliscope

1) Preliminary notes

Initial data come from French and Canadian Origin-Destination surveys (from 2009 to 2019).

Only trips occurring weekdays (Monday-Friday) have been considered. Number and proportion of present population aggregated by district and hour have been estimated from survey data. They are therefore subject to a statistical margin of error.

55 city regions are included in the actual version of the Mobiliscope (v4.0).
To access city region, use magnify tool . You can also select city region in the drop-down menu .

2) Select a map

In the left-hand menu, you can choose one indicator and the map representation, eitheir as aof the total population, or in number or in flows.
To get informations about indicators, click button on the right side.


With flows maps you get number of non-resident people at district level. With links (on mouseover), you can know their main district of residence. This mode is not available on touch screens.


3) Change hours

At the top of the screen, click play button in the timeline to scroll through the hours.


4) Explore a specific district

Select one district by clicking on the map and have a look on the chart at the top right corner of your screen.


With this chart, you can follow daily evolution in the selected district (for the selected indicator).


By clicking on 'stacked' mode, you can see all groups of the selected indicator.


Colors on maps and charts have the same color code than the left-hand indicator menu. In the above picture, public transportation are in blue, private motor vehicule are in pink and soft mobility in green.

5) Explore spatial segregation

At the lower right corner, the chart give information about segregation level in the whole region for the selected indicator.


To get informations about the two available indexes (Duncan et Moran), click button on the right side.

6) Change map background

Two OpenStreetMap layers can be displayed: a simple information layer and a more detailed one (by clicking in the ) :


In French city regions, you can also display the layer of 'Poverty Areas' via the layers menu .


7) Download data

By clicking on the button above the central map, you can download data agregated data by district and by hour. By clicking on the button next to the bottom graph, you can also download segregation data (Duncan's or Moran's index) in the whole region over the 24 hours period.

Open source and open data

The Mobiliscope is developed in the spirit of open science and FAIR principles. We do our utmost to ensure that our programs and data are "easy to Find, Accessible, Interoperable and Reusable."


The Mobiliscope has been developed using HTML, CSS (framework mini.css), javascript and PHP. The geovisualization has been coded in javascript and relies on D3.js - developed by Mike Bostock - and Leaflet library. OpenStreetMap layers and maps drawn with D3.js are displayed with Leaflet.D3SvgOverlay, a plugin under MIT license.

Space-time data are locally stored as geojson files for spatial data and csv files for data without geometry. They are automatically generated from two R scripts: the first one transforms 'trips' data into 'hourly location' data; the second one produces all the files necessary for (carto)graphical representation.

Programs (including geovizualization and data processing programs) are available in a public github repository. Programs are under copyleft AGPL licence With AGPL license, users can use and modify programs as long as they redistribute the modified programs under AGPL license and indicated sources as follow: « Programs under AGPL license issued from Mobiliscope (v4), a geovizualisation platform to explore cities around around the clock ( ».



Users can freely use the French data displayed in the Mobiliscope. These data are made available under ODbL license. Users are free to use and adapt these data as long as they redistribute a version of their adapted database under the ODbL licence and that they attribute the original sources as follows: « Data under ODbL license issued from Mobiliscope (v4), a geovizualisation platform to explore cities around around the clock (, from initial data [to be completed according data sources indicated in the map or in the OdBL license attached with the data] ».

Hourly data location in French cities (format .cvs and .geojson) can be downloaded in the Mobiliscope platform (as well as the data dictionnary). With these files, we have also attached a pdf document summarizing the terms of the ODbL license and the sources to be indicated. To download the data, click the button

  • either above the central map to get hourly location data for every district of the seclected city region (and according to the selected indicator and the repsentention mode)
  • or to the side of the lower chart to get houlry values of segregation index (Duncan or Moran) for the whole region and according to the selected indicator.
