Understand a Cluster

Hello WFS user,

A cluster in the Wildfire Solution from OroraTech serves the purpose of monitoring the fire growth in real-time. We want to make sure that you are aware of the advantages that satellites offer to fire monitoring. As satellites represent an irreplaceable source of continuing monitoring, day and night, through smoke and with a wider sight range.

Clusters are the aggregation of what we call hotspots. Once you click on one of them you will see at first glance:

The cluster shape (turquoise outline) is a vision of the fire event from above. It represents the aggrupation of all contained hotspots that are temporally and spatially correlated. Then we track relevant information on active and historical wildfires and their perimeters like the worst case affected area
The first submenu Details will display information about the first and last detections, coordinates, affected and burnt area, and metrics to determine the possibility of it being an actual fire.
Then we come to the submenu Timeline which shows the latest information that users have submitted for the cluster.

The third submenu on the list will display weather information at the current moment you are visualizing the web app. This submenu includes an interactive graph that will show historic and forecast weather data, as well as the 30-30-30 rule (benchmarks that reflect extreme fire prone weather conditions).

Then comes the LEO Satellites Overpass List for which we created this document to explain it in detail.

The submenu Fire Spread shows the automatic and instantaneous simulation we provide with our OT Fire Spread product. To read more about it please click here.

The submenu Burnt Area shows the product OT Burnt Area with a resolution of 10m calculated by comparing high-resolution images from before and after a fire has occurred.

The submenus Fire Radiative Power and Hotspots display information related to each detection and the sum of the intensity of the energy emitted by the heat source at the acquisition time. To understand hotspots on a deeper scope please read this article.

The submenus Affected Area and Land Cover Distribution show the estimation of the affected area based on the resolution of the instruments that detected hotspots and the land cover within the cluster according to the Land Cover Map provided by the ESA.

Last but not least, here you have an explanation of the meaning of the different outlines of the clusters. All clusters with at least one LEO hotspot will have a lined outline whereas clusters integrated by only GEO hotspots will have a dotted outline. This is useful to identify at a glance the size and therefore impact of a cluster event.
