Population Density Data API description v2
API description
The “Population Density Data” API provides population density estimations for a specified geographical area and time interval.
With this API, developers can retrieve estimated population density data per km² for each cell in the requested area and time range. The response provides three estimation values: minimum population density, average population density and maximum population density.
The API is especially relevant for drone and advanced air mobility use cases, where operators need to assess the number of people potentially exposed under a planned flight path. This helps developers support ground risk assessment, route planning, flight timing decisions and mitigation planning before an operation takes place.
The estimations are derived from anonymized historical network data and prediction models. The API does not return personal data and includes privacy-preserving mechanisms such as low-density suppression when the information available for a cell does not meet the required anonymity threshold.
The API provides:
A Population Density Retrieval function that allows an application to request population density estimations for a defined area and time interval.
A cell-based population density response using geohashes or equivalent grid cells, including minimum, average and maximum estimated population density values.
A privacy-preserving output model where cells with insufficient data are not exposed as population estimates and are returned as
LOW_DENSITY.Support for synchronous or asynchronous response handling, depending on the size and processing complexity of the request.
Use Cases
Drone ground risk assessment and SORA support: Drone operators and U-space service providers can use the Population Density Data API before a planned flight to estimate the number of people potentially exposed under the flight path. This supports ground risk assessment and helps determine whether the planned operation is acceptable for the intended time window.
Drone route and flight-time optimization: Drone applications can compare different routes or time slots and select the option with lower population exposure. This helps operators avoid crowded zones, reduce operational risk and identify safer alternatives before the flight starts.
Emergency response planning: Public authorities and emergency management platforms can use population density estimations to understand where people are likely to be concentrated during a crisis, incident or large-scale disruption. This supports better prioritization of resources, evacuation planning and response coordination.
Urban planning and infrastructure analysis: City planners can use anonymized population density estimations to understand how areas are used over time, supporting decisions on infrastructure, mobility, public services and urban development.
Event management and crowd planning: Event organizers and public safety teams can use population density estimations to plan security, access flows, facilities and operational resources around venues and high-attendance areas.
Data-driven marketing and campaign planning: Marketing teams can use aggregated population density insights to identify high-density areas and optimize the placement, timing and reach of location-based campaigns.

Benefits
Safer drone operations: Helps drone operators identify lower-risk routes and time windows by estimating the population potentially exposed under a planned flight path.
Support for ground risk assessment: Provides population density inputs that can support SORA-related assessment processes and help operators evaluate whether additional mitigations may be required.
Route and time optimization: Enables applications to compare alternative routes, zones or flight times based on estimated population exposure.
Privacy-preserving network insight: Uses anonymized and aggregated network-derived data, with mechanisms such as low-density suppression to avoid exposing information where anonymity thresholds are not met.
Operational Efficiency: Helps API consumers automate planning decisions, reduce manual analysis and improve resource allocation.
Improved emergency and event planning: Supports better assessment of population concentration patterns for emergency response, crowd management and public safety planning.
Developer-friendly integration: Provides a standardized CAMARA interface for accessing population density estimations across operators through a consistent API model.
