Why not? It's not exactly hard? The exact capabilities aren't public, but there are companies that provide daily synthetic radar captures for the whole globe and similarly companies that do this for imagery. It would take ages but I think you and I could both right an algorithm to classify if an image or high map has an aircraft carrier in it? Even if you can't get data for the whole globe taking a photo of a 10 mile of ocean every 10 minutes and shifting the center based on where a boat isn't hard. There aren't that many aircraft carriers. Aircraft carriers and tanks are both capable machines built and designed for a different environment than we have now. They can still be useful. Most countries don't have the ability to image the whole globe or lob weapons across an ocean, but I'm pretty skeptical they'd survive long in a war with say China
