Newcomer contributor in JuliaGeo and co. - Help me get started!

@NHDaly just shared this on Julia Slack: which I guess counts as one more!

Yeah, Maps.jl was sort of a half-day sprint over the holidays to see if i could quickly get a cool mapping package up, built on Makie. I ended up spending a good deal of time just learning Makie in the process.

If it makes more sense to merge that bit of work into GeoMakie, i’m 100% down with that!


Because in this post there was some discussion regarding organizations and moving packages to organizations, I want to cross link the following two posts: 1 and 2 from a similar discussion in a different thread. They “outline” in some sense the story of JuliaDynamics, which some users believe to be a successful case of an organization around a scientific discipline.

I don’t want to derail this topic here to a discussion about GitHub orgs and moving packages. But I do think that such a discussion would be helpful, as there are numerous benefits in it, and it has started here. Maybe someone is willing to open a new Thread under Domains/Geo ? As I currently own 0 packages related with Climate and Geo, I don’t think I can open it.

FYI, GMT.jl already belongs to an organization, just not a Julian one.

(Copying some of my responses in this thread over here.)

The process for getting involved in JuliaGeo development is described here:

The JuliaGeo organization is loosely-tied (in name and focus) to I agree with Martijn’s comment: membership in an organization/team are a way of managing permission settings for packages that you co-develop with people, and are best used for that purpose. I’m sorry about the ambiguity in the name, here is the thread where the discussion for it happened:

For packages that are oriented along scientific domains, sometimes it might be worthwhile to have github organizations (that might be cross-language efforts) around it. If there is a collection of packages that works well together for oceanography (that doesn’t otherwise depend on JuliaGeo), it might make sense to create a separate github organization for it: that might give you more freedom to take it in a direction that facilitates development for those packages you are interested in.


FYI, Gael Forget has started JuliaOcean, an organization to host packages around ocean stuff. It’s pretty empty for now but hopefully it will fill up and help new Julia users discover ocean-related packages and serves as a community of sorts :slight_smile:

since many from the geo field are in this thread and, I’d like to ask a quick side question: is there any way to read ecmwf reduced gaussian grid grib files directly into julia yet? I’ve always had to revert to a pythn-based intermediate step that I’d love to skip.

“reduced Gaussian grid, which has quasi-uniform spacing over the globe”

You shouldn’t hijack a thread! Most geo-folks presumably watch the geo subcategory:, so posting there should reach most.

Also, for quick questions, consider using the #geo channel on


your right! I’ll ask there
