Why does some post-catastrophe imagery contain cloud, smoke and other artefacts?
In order to capture and publish post-catastrophe imagery as quickly as possible, we sometimes will have to fly in conditions that we would normally consider sub-optimal for our standard captures. This includes potentially flying under high cloud layers or at higher than usual altitudes due to emergency Air Traffic Control…

How does Nearmap decide which events to capture for Post-Catastrope surveys?
Events are assessed based in criteria such as the scale of impact to communities, infrastructure, and property, and the geographical areas affected by the event. Due to the variability of these types of events, Nearmap assesses each on its own merit based on certain criteria. For example, a significant hurricane that is…
How fast is post-catastrophe imagery captured after an event?
We endeavour to capture as quickly as possible after an event, usually within days.

What resolution is post-catastrophe imagery?
The post-catastrophe program is captured as high-resolution Vertical (orthogonal) imagery at 5.5cm-7.5cm GSD (ground sampling distance) per pixel. The resolution can vary depending on the ceiling height of clouds, but we aim for 7cm or higher. Learn more about Nearmap Vertical imagery specifications.
