Hi everyone, just wanted to help announce that https://github.com/JuliaGeo/GADM.jl has been released; it is developed by @zerefwayne under https://fellowship.mlh.io/. The package provides polygons/multipolygons for all countries and their sub-divisions from the GADM dataset. It dynamically downloads the required data and gives you a simple API to interact with it.
A huge shoutout to @juliohm for his guidance throughout the project. Shower the project with some stars if you like it.
