Grab any free image of a top down view of a place you know, post it, and let's see who can find where it is! if people struggle to find it, post hints along the way.

Before trusting any image, experts do a quick gut check. What do you instinctively look for when judging whether a photo is any good? The same idea applies here.

Good news for newcomers: alot of EO work can run on free data. What would you try first if the imagery cost you nothing?

What's your take on resolution and what do you favour? fine detail, lots of colour bands, or frequent revisits. For your work, which matters most - and what would you give up?

New to this group or EO? Just tell us what you'd love to monitor, and the group may help give you pointers on what might suit - optical, radar or thermal
