Where to Actually Find a Good Physical Map of North Africa
I spent about three weeks last year trying to assemble a clean, accurate, large-scale physical map of North Africa for a client presentation. What I learned: most of what you find online is garbage, and the few decent ones are either behind paywalls or have political boundaries smushed over top of the terrain data until it's unusable. The problem starts with data sources. If you grab a Physical North Africa Map from a random free map site, you're usually getting SRTM-derived elevation data that's been generalized to hell. The Atlas Mountains look like a gentle ripple instead of what they actually are. The sand seas around the Sahara get flattened into uniform low-elevation yellow. Not useful if you care about readability.
How to Build Your Own Without Losing Your Mind
Start with the underlying terrain. The best free source for North Africa is still NASA's SRTM 90m data, but you want the gap-filled version from CGIMare or the newer Copernicus DEM at 30 meters. It costs nothing and you don't even need to register. Download tiles covering roughly 30°W to 35°E longitude and 15°N to 37°N latitude. That gets you everything from the Atlantic coast of Morocco through Egypt. Stack it in QGIS. Set the projection to a proper equal-area or equidistant one for North Africa — EPSG 102029 (North Pole Lambert Azimuthal) works fine for regional overview, but if you need conformality for any reason, go with UTM zones. The whole strip spans UTM 28N through 36N, so you'll be working with multiple zones. Render the elevation with a layered shading approach. A simple hillshade from a single sun angle looks amateurish and washes out theTell Atlas and the High Atlas ridgelines. I pull two hillshades — one at 315° azimuth and one at 135° — blend them at 50/50, then composite that over a colorized elevation ramp. For the ramp I use a modified GMT color table with the blues for the Mediterranean shelf, the pale tans for the Sahara interior, and deep ochre/browns starting at roughly 800 meters for the Atlas system. Everything below 200 meters in the interior stays pale so the Erg regions read as empty without looking flat.
One thing most people miss: the Nile Valley and Delta need separate treatment. If you just run the whole raster through a single color table, the Nile corridor gets swallowed by the surrounding desert colors because it's not dramatically lower than its banks in terms of elevation range. I mask out everything within about 50 km of the river centerline and apply a distinct green tint at low saturation so the valley shows up without looking like a video game health bar.

The Edge Case That Bit Me
Here's the specific problem I ran into: the western Sahara transition zone. The elevation data from SRTM has a known artifact where dune fields register as spiky noise because the radar sees the dune crests but misses the troughs. I had a client who needed the map to be publication-ready and noticed the Erg Chech and the western Grand Erg Oriental looked like they'd been hit with a grain filter. It was unacceptable. The workaround is to blend the SRTM data with the ALI landform classification layer from the USGS or the newer Copernicus Global Land Service surface cover products. You mask out the dune fields using the land cover data, fill those areas with the nearest-valid-elevation interpolation from the surrounding stable terrain, and re-render. Takes about twenty minutes once you've set up the processing chain, and it fixes the problem cleanly.
Finishing Touches and Export
After the terrain render, add political boundaries as a thin gray line — 0.5 pt at print scale. I keep them light because the whole point of a physical map is that the terrain dominates. City labels go in a clean sans-serif, sized by hierarchy. Only capital cities and major urban centers get bold type; everything else fades out. For North Africa that means Algiers, Cairo, Rabat, Tunis, Tripoli, and Khartoum get prominent labels. The rest get small caps or italic at most. For export, I use GeoTIFF at 300 DPI minimum for print, or PNG at 4K resolution for digital. Never export from QGIS as a low-resolution screenshot and call it done — I see that constantly and it's painful to look at. If you need a quick shortcut and don't want to build this from scratch, Natural Earth at 1:10m or 1:50m resolution has a decent physical base layer you can pull from, but you'll be working with simplified coastlines and no modern political data. Good enough for rough drafts, not for anything going to a client who knows geography.
The entire process — download, process, render, add labels, export — takes me about forty-five minutes to an hour. Someone who doesn't know QGIS well will probably spend two or three hours the first time through. After that it's mostly muscle memory.
