Is this mod compatible with other mods?

I tried it in my megamodded SA run and it's worked wonders.

Do you have any impact on calculation?

I don't have any runtime calculations, everything is done via vanilla functionalities. However, chunk loading and generation is not lightweight, so beware possible performance issues. Radars are heavily optimized internally, but area scales quadratically so...

Can i use assets/source code?

Sure - The assets are recolors of vanilla entities and are subject to Wube's Content Policy. All other resources, code included, are under MIT. Technically they're under WTFPL, but it's not accepted by Factorio's Website
