    Tangent question, I know of services like Planet Labs, Maxar... is the capability there now assuming you had money, where you could tag a ship from space and watch it travel (I know there is something like ADSB for ships) but would be interesting.

      It's still at the "technical challenge to fuse data from AIS [ADSB for ships, complete with spoofing and transponders being turned off] to [generally] static images from multiple different sources" stage, at least unless you've got the budget for a video satellite to stick in a geostationary-ish orbit

        I also wasn't sure how good satellite image quality is where you can match a ship from above, maybe the pattern of the freight containers could help.

        And track I didn't indicate frequency, it's not per minute, but say hourly.

    very cool

    Once I figured out how to use the UI I did 2 scans. first one I had to zoom in before the identification boxes popped up. At first I thought it didnt do anything

    Second scan I put over a local aviation museum with a mix of helicopters, unusual planes, cars, buildings, and other equipment. I was surprised to see everything identified correctly, though it missed a single helicopter.

    I'd love a little bell or notification when the scan completes, as I hit 'scan', switch to a different tab and then forgot I was waiting

      Thanks for trying it out. The detections not all appearing before zooming is because I added a LOD (level of detail) rendering method, so if hundreds of thousands of objects are detected, it won’t crash the system. Only the areas you’re looking at render, and the more you zoom in, the more objects are displayed. It was a pain to set up, but it’s worth it. The notification idea is great, and I’ll add a sound to play when a scan finishes.

        Thanks, makes sense to me. I was just confused at first since i thought maybe it didnt do anything or my adblocker was making it go weird

    Great idea, almost impossible to use on the mobile due to the mobile UI.

      Thanks for the feedback. I’ve resolved the UI issues on mobile.

    This is cool. I'll give it a go
