We start by download and save in cache the geopackage file with Mozambique data. Note, a downloading message will be printed only once, and in this case it will say
Downloading geographic data for country MOZ provided by the https://gadm.org project. It may take a while. The file gadm36_MOZ.gpkg (after uncompressing) will be stored in c:/j/.gmt\cache
using GMT mozambique = gadm("MOZ");
imshow(mozambique, proj=:guess, title="Mozambique")
Next let us add all the provincies of Mozambique. For that we'll use the country code as parent and the option
children=true to indicate that we want all provincies boundaries.
mozambique = gadm("MOZ", children=true); imshow(mozambique, proj=:guess, title="Provinces of Mozambique")
To know the provinces names such that we can use them individually for example, we use the option
"Cabo Delgado" "Gaza" "Inhambane" "Manica" "Maputo" "Maputo City" "Nampula" "Nassa" "Sofala" "Tete" "Zambezia"
Now we can plot only one of those provinces and its children
CD = gadm("MOZ", "Cabo Delgado", children=true); imshow(CD, proj=:guess, title="Cabo Delgado")
