I am here to introduce the final stable version of [GeoRegions.jl](https://github.com/JuliaClimate/GeoRegions.jl) at v5 (don’t ask, it’s been a bumpy road with a _lot_ of breaking changes). I hope this package will be useful especially to people who deal with geographic gridded datasets.

GeoRegions.jl provides three basic functionalities:

- Defining a geographic region of interest (rectilinear or polygonal) using the `GeoRegion` type
- Extract longitude-latitude gridded datasets of a `GeoRegion` of interest using the `RegionGrid` type
- Extracts [ETOPO 2022](https://www.ncei.noaa.gov/products/etopo-global-relief-model) topographic data from the OPeNDAP servers

Please see the [documentation](https://juliaclimate.github.io/GeoRegions.jl/stable/) for a more in-depth tutorial and examples.

Inspiration for this package was taken from the python package [regionmask](https://regionmask.readthedocs.io/en/stable/)

I think GMT.jl can do all of that (plus a _some_ more of topo/bathymetric data). But it’s nice that you made it with a better documentation (some day I’ll _steal_ a bit of it 🙂 )

I’ve always viewed GMT.jl as more a plotting/mapping tool. Also, most climate scientists I know do not use GMT or know how to use GMT. I view GeoRegions.jl to be a simpler, more lightweight package that is more easily extendable to other packages for various datasets, especially in the defining and saving of geographic regions of interest.

But it’s way more than that.

Here I agree with you.
