Population Density Data - CAMARA 0.2

Population Density Data API is based on data provided by Orange Business product called Flux Vision.

The algorithms used by Flux Vision permanently guarantee irreversible anonymization by deleting all personal data and making it impossible to identify a natural person, as well as to re-identify them directly or indirectly.
These exclusive algorithms, developed by Orange researchers, are the fruit of several years' research and comply with the recommendations of the French Data Protection Authority (Commission Nationale Informatique et Libertés - CNIL), recognized as one of the most protective bodies in the world, to whom they were presented during the design of Flux Vision and before its launch. In fact, the technical data processed as part of Flux Vision are not considered personal data and are therefore not subject to the GDPR.

Data anonymization is irreversible and in real time according to an exclusive technology developed by Orange teams. This technology, combined with the aggregation of mobility indicators, ensures that no individual can be traced. The data used is not stored in accordance with current regulations.

To meet regulatory requirements, the smallest analyzable population sample, even with socio-demographic criteria such as age range and male/female distribution, never represents a population of less than twenty people. This makes it impossible to analyze the behavior of a single individual.

No raw data from the mobile network is or can be archived, either before or after the solution goes live. The launch of indicator calculation therefore coincides with the launch of raw data collection and processing. Only anonymized and rectified indicators can be stored to create a history.

Flux Vision is a service designed to provide statistical indicators for analyzing the presence, movements and socio-demographic profiles of people in one or more specific geographical areas. It can be used for a wide range of applications: studying people's movements, analyzing tourist numbers in a town/region or at a sporting/cultural event, analyzing footfall in a shopping area or determining catchment areas. The solution provides access to innovative, permanently available, guaranteed and secure information on very large sample volumes, without the need to deploy equipment in the field. 

The solution is based on raw technical data from the Orange mobile network, processed and anonymized in real time by algorithms derived from Orange know-how, to produce statistical indicators which are then adjusted to the total population present, and delivered in the form of study reports.

As input, we only capture technical information from the Orange mobile network (Orange, Sosh or equivalent B brand and international roaming subscribers). Nevertheless, we perform a statistical adjustment step based on various criteria, such as the market share of other operators in the local area, to statistically represent the overall population. This method enables us to estimate the number of people actually present, based on observation of mobiles on the Orange network. These statistics are macroscopic and anonymous.

Adjustment enables us to estimate the number of people actually present, based on observation of mobiles on the Orange network (Orange, Sosh or equivalent B brand and international roaming). This adjustment includes several statistical models, taking into account the specificities of signaling on the mobile network, and Orange's market shares on different sub-populations.

Population Density Data API is based on data provided by Orange Business product called Flux Vision.

Flux Vision has collected a long history of anonymous statistics on the covered territory. By the use of Data Science techniques, predicted density is calculated based on this long history of data and recent trend. Maximum and Minimum values provided as part of API output, are calculated based on observation data from past history.  

Population Density Data API is based on data provided by Orange Business product called Flux Vision.

Observation of data is made at the lowest administrative resolution available (IRIS level for France). Using Flux Vision’s statistical models and considering building density on the observed area, data is distributed at geohash7 level. 

A Geohash is a unique identifier of a specific region on the Earth. The basic idea is that the Earth is divided into regions of user-defined size and each region is assigned a unique id, which is called its Geohash. For a given location on earth, the Geohash algorithm converts its latitude and longitude into a string. This string is the Geohash and will determine which of the predefined regions the point belongs to. Generally, points within close geographical proximity will have the same Geohash. 

Our Production APIs operate in a live environment, delivering real-time data and full functionality. They are intended for use in your actual applications and services, providing you with the tools needed for operational deployment. 

You can access complete API functionalities and real datasets, enabling you to build and deploy applications that rely on live data.

Our Trial APIs operate in a live production environment but come with specific limitations to allow you to explore their functionalities without full commitment. They are designed for you to preview features and test integrations while adhering to certain constraints.

You can access real data and functionalities, but with restrictions on the number of API calls, types of recipients, or duration of use. This allows for practical testing in a real-world context.

Our Sandbox APIs provide a secure testing environment where you can experiment without affecting real-world data. This allows for safe experimentation and testing of the API's features using fictitious or limited data.

You can make API calls that return responses, which may come from our lab infrastructure or be simulated, enabling you to test integrations and functionalities in a controlled setting.
