Ah. So they’ll see what info the space view gets and compare that with information on the ground. Such as seeing a certain “color” in an area and finding that the area has a forest of a certain kind of tree.

From the space view, they can look at every disease location and see if they have anything in common (such as certain “colors” in the image), then see on the ground if those colors at those locations seem to have any significance.

It reminds me of the fellow who noticed that areas in a USA desert which were known to have gold were showing a certain “color” in satellite images. The meaning of that signal was not known. So he simply drove out to one of those areas and pointed a duplicate of the satellite’s detector around the scenery until he found stuff which was emitting what the satellite had detected. Once he had rocks in hand it was a simple matter to identify them and study further the relationship between that mineral and gold deposits. Of course, the purpose was to learn if new gold areas could be found in the images.
