The UNGRD announced the activation of the International Charter and the Mesa Geomática to guide the assessment of material damage using satellite images and aerial flyovers. This announcement was published on August 14 at 08:09, although the exact activation time is not specified.

Mapping activation

To address the scale of the destruction, the Mesa Geomática, led by the UNGRD, mobilizes several partner entities. This collaboration includes the International Charter, NASA DRCS, IGAC, FAC, UNDP, and INDRA, working together to provide precise visual data of the affected areas.

Satellite image processing

UNGRD says 166 high-definition satellite images have been processed. Airbus supplied very detailed views of Cali, Cartago, Manizales and Pereira. These data complement field observations but do not by themselves constitute a final damage inventory.

Aerial reconnaissance flights

In addition to satellites, aerial photographs were prioritized in 85 municipalities. The flyover and collection of these images have already been completed in 13 municipalities across the departments of Valle del Cauca, Chocó, Risaralda, Caldas, and Quindío.

Objectives of the imagery

UNGRD presents the imagery as support for identifying damage to homes, roads, infrastructure and essential services. It is neither a final damage assessment nor a repair programme.
