The first thing to understand is the difference between de facto and de jure boundaries. De facto data draws borders according to who actually controls territory on the ground, while de jure data follows legal or claimed boundaries. A dataset's default choice determines what your Morocco polygon includes.
Natural Earth, one of the most widely used free sources, draws boundaries by de facto control in its default files. For Morocco this means the polygon includes the part of the southern territory west of the berm that Morocco administers, following the line of control.
Beyond a single default, Natural Earth publishes point-of-view (POV) worldview files that let developers render boundaries from a specific country's perspective. These include a Morocco POV variant designed to reflect the Moroccan view of disputed territories.
Using a POV file, you can present a unified Morocco that includes the southern provinces as one continuous polygon. The same project also ships disputed-area line files, so you can optionally show contested segments if your application needs to surface them.
If your product serves a Moroccan or Morocco-aligned audience, the Morocco POV polygon or an equivalent unified file is the natural choice, presenting the country as one territory. If you must serve a strictly international or legalistic context, a de jure or neutral file may be required.
Whatever you pick, document the decision and keep the source consistent across your stack. Mixing a unified country polygon with a separate Sahara polygon from another dataset can create overlaps, gaps or double-counted areas in spatial queries.
Before shipping, verify three things: which control model the dataset uses, whether a POV variant matches your intended audience, and whether subdivision files agree with your country polygon. Test a point inside Dakhla to confirm it falls within your Morocco geometry.
Finally, respect the license and attribution terms of your source. Natural Earth is public domain and friendly to customization, which is why it is a common base; community sources like OpenStreetMap give even finer control through their disputed-border tags if you need to build a custom rendering.
By default Natural Earth draws de facto borders, so Morocco's polygon includes the part of the southern territory west of the berm that Morocco administers. POV files let you render a fully unified version.
Use Natural Earth's Morocco point-of-view worldview file or an equivalent unified dataset, which renders the southern provinces as one continuous polygon with the rest of the country.
Avoid mixing a unified country polygon with a separate Sahara polygon from another source, which causes overlaps or gaps. Pick one consistent dataset, document it, and test points in southern cities.
