Activity Data

The Activity API returns nighttime light radiance and a derived development index for any coordinate across Latin America. Data is sourced from the VIIRS Day/Night Band 2023 annual composite at 500m resolution. It is useful for understanding urbanization, economic activity, infrastructure presence, and site development potential.

Click anywhere on the map — or type coordinates below — to retrieve activity data. Radiance will be 0 for oceans, uninhabited areas, or locations outside the coverage area.

During the day, much of central Argentina appears sparsely populated. At night, VIIRS data reveals a network of towns through visible light.

What the Response Tells You

{
  "radiance": 81.2,
  "development_index": 0.83,
  "activity_level": "very_high"
}
radiance — raw light intensity measured by the VIIRS satellite sensor. Higher values indicate more artificial light at the location.

development_index — a 0–1 score where 0 is completely unlit and 1.0 represents a bright city centre. Useful for comparing or scoring locations without needing to interpret raw radiance values.

activity_level — a human-readable label: minimal, low, moderate, high, or very_high. Useful for filtering or displaying results without additional processing.

Retail site selection teams use it to assess whether a location is in an active commercial area or a low-activity zone. Logistics services use it to prioritize coverage areas. Risk and insurance teams use it as a proxy for infrastructure presence and urbanization. It pairs naturally with population data to build richer location scores.
