https://earth.nullschool.net https://earth.nullschool.net has a range of different projections available (on top of the main functionality of the site, which is itself a pretty cool map of wind/weather/atmospheric patterns).
The cool thing is that you can pan the map in the different projections, which isn't possible with most maps: most tend to be static images.
- grogenaut 3y agoPretty cool to think about the amount of work going on behind the covers to alter these projections on the fly. And how costly it was to build them originally by hand.
- tony_cannistra 3y agowork, sure, but not _that_ much. It's affine transformations / some fast linear algebra, for the most part. Your second point is for sure true, though.
- HPsquared 3y agoI wonder if anyone ever came up with an elaborate mechanism connected to a pen.
