Question

The last 3 weeks have said “not ideal conditions” and no usable image exists. It sure hasn’t been cloudy that much. Anyone else not getting images?

Answer

Yeah we had some like that too, but honestly I don’t get very much useful input/data from those satellite pics so it’s not a big deal IMO.

Answer

I'm probably just an idiot here but I dont understand what the maps are showing me? The key on the side says from 0-1 and the map is red, green, and yellow. Is that a measurement of heat or how green vs brown the field is?

Answer

Hi there,

The images show the "Enhanced Vegetation Index" - which is a measure of vegetative vigor calculated using the colors of light reflected in the image. It ranges from 0 (red) to 1 ( green), with red indicating less crop growth and green indicating denser vegetation, as Matt calls out above.

We have some more detail here, and certainly reach out if you have more questions or are interested in more detail:

Also, while we do our best to detect clouds in the images and then filter out images that aren't useful due to cloud cover, this process isn't perfect. There's actually a filter at the bottom of the images where you can toggle the cloud filter on/off. It's on by default, but if you want to see what an image looked like before we removed any parts of it due to suspected cloud cover, you can turn that off and then see exactly what the satellite saw. You can also check out the "Raw Image" option - where it's usually pretty easy to visually see if the image was in fact blocked by clouds.

Hope this helps and please let us know if there's any questions on this!
