Importing GADM boundaries into DHIS2

Hi everyone

Was wondering if there was a simplified process to import GADM (https://gadm.org/) boundaries into DHIS2.

For example, if I have a global hierarchy of some sort and only want to import the country-level boundaries.

ie.

Global

—Regional

-----Country

Thanks,

Nick

Hi Nick,

I have been working on a solution to import all the levels, but if you are
really only looking for the country level, it is quite straightforward. The
main obstacle is the size of the file, which can be significantly reduced
by a) filtering out polygons that you don't need (e.g. Antartica) and b)
simplifying those you do need, e.g. using http://mapshaper.org/ (which can
also be downloaded and run locally on your laptop).

The filtering can be done in several ways.
a) It seems you already have the orgunits in your tree, which will then
serve as a filter itself. Do you already have three-letter ISO codes for
matching?
b) If you did not already have the countries (or no good way of matching),
you can use the ogr2ogr tool of the GDAL package like this:

ogr2ogr -where "GID_0 in
('AGO','BDI','COG','COD','GNQ','GAB','RWA','STP')" countries.shp
gadm36_0.shp

c) Since we now require PostGIS (from 2.30), that is the most versatile
tool for all of these manipulations (though not sure if the simplification
algorithms are as good as the ones Mapshaper offers).

I attach a file of all countries reduced to 4%, let me know if you are able
to use that directly.

Thanks Knut, I was able to import directly from the file you shared via matching the ISO codes. Very helpful!
