Thanks Markus, I also came across this and another resource, so part of my needs are met.
however, i notice that these data are derived products, where a pixel is designated as having a fire based on the temperature anomaly. thi is the main reason if anyone is following on the firemaps available on google maps that we are getting huge polygons - basically the boundaries created around any pixel with a large-ish anomaly. is there a quick automation workflow possible where False Color Composites of near-realtime imagery using the thermal band can be created, which can be updated once a day at the click of a button; and then overlay the FIRES derived datasets on top? This would allow one to visualize the earth surface while also overlaying the derived product. i'm imagining a workflow which automates the finding of imagery as well, because that part of the workflow (going to the DAAC and finding the sensors , path, row etc etc) seem as tedious as it ever was..
