[Question] [Suggestion] Adding Projections #93

Open mreel opened 4 years ago

mreel commented 4 years ago

Hey, first of all, not sure if this is the right place to post this. If not, I'm sorry, where would be a better place?

I was thinking about making an extra projection (Robinson) and I was looking at the code. It doesn't look difficult at all, so I'll probably do it, maybe even other projections too, but I can't figure out what the metersPerUnit method does, and so, have no idea how to write it, further clarification would be greatly appreciated.

Additionally, as I said, adding the projection seems very easy, easy enough for modpack makers/ advanced users to add them. Might it be an idea to allow for custom projections through something like JSON?

So... there is already Equal Earth which is very similar to robinson with the additional benifit of having no area distortion. https://matzav.com/wp-content/uploads/2018/09/eerob2.jpeg

I know, the reason I was thinking about adding Robinson is for possible better performance.

What do you think about user added projections? Meaning local among other benefits.

orangeadam3 commented 4 years ago

I guess... I probably don't have time to do it myself but someone could pull request it. What do you mean user added? We already had a github user contribute the transverse mercator.

I meant by modpack makers for example, more specifically I was thinking in the config folder, probably with JSON since the only thing really needed is coordinate conversion and whatever the metersPerUnit is (Still wondering).

I apparently didn't really say it in my original post, but I was also thinking about adding the gall stereographic projection. I don't believe there is a similar one implemented yet.
