Very cool

Congrats, this looks nice

Does this app render the flights to fit the curvature of the earth?

Was looking for something like this during the New Jersey drone flap to help identify distant flights from the perspective of someone on the ground



Thanks!

The app currently renders aircraft and maps on a flat plane using latitude, longitude, and altitude, via the sphericalmercator library:

https://github.com/mapbox/sphericalmercator

My understanding is that the ADS-B latitude and longitude are based on the WGS 84 coordinate system, which accounts for the Earth's curvature, but the app itself doesn't project these coordinates onto a curved surface.

I'd appreciate suggestions from HN users with map projection expertise on how to accomplish this. I'm also interested in learning more.

One of my next projects is to get a better understanding of GIS coordinate reference systems in order to be able to create 3d globle renderings of the data. I purchased the following two books to better understand map projection implementation:

3D Engine Design for Virtual Globes by Patrick Cozzi and Kevin Ring

Flattening the Earth by John P. Snyder
