Even for emergencies like flooding where it is very important to know which areas are flooded and which are not, I think presently there is no satellite based system which can give this information anywhere near realtime with anything close to the required resolution. So in the absence of such I assume the information will have to be gathered from ground reports and areal surveys, which I would think will be extremely time consuming and labour intensive to gather and collate and form a full picture of the flooding.
- casefields 5y agoEven the biggest of floods is a localized problem. A fleet of drones can give you live feeds of the entire thing. The caveat is of course the military has the best ones, and there's an uneasy balance of allowing military use on home soil. Baltimore has been leading the charge on aerial surveillance: https://www.baltimoresun.com/news/crime/bs-md-ci-cr-aerial-program-review-spy-plane-20201212-a5cnfitg75dexdsjgzcciqdhye-story.html https://www.baltimoresun.com/news/crime/bs-md-ci-cr-aerial-p...
