Getting a proper Map Of Western Hemisphere without the usual crap
You grab a Western Hemisphere map and you immediately notice something most sources gloss over: most of them are just two separate continents shoved onto one sheet, which works fine for a classroom poster but falls apart fast if you need accurate spatial relationships between, say, Lima and Lisbon. I ran into this exact problem when a client needed a single-map view for a logistics presentation that covered routes from Buenos Aires to Vancouver. Standard projections like Mercator distort everything north of about 40 degrees latitude to the point where it looks like Alaska is twice its actual size relative to Brazil. Not useful. The honest answer is that no single map projection handles the entire Western Hemisphere well across all purposes. But there are workable options if you know what you're looking for.
Where to Find a Downloadable Map Of Western Hemisphere That Actually Works
Natural Earth is the starting point. Their vector data at 1:50m and 1:10m scale gives you clean coastline boundaries that render properly in QGIS or ArcGIS. The coastlines come ready to project, and you can stack them onto almost any projection without fighting geodeticDatum mismatches. I downloaded the 1:50m coastal polygons last year and rebuilt a Western Hemisphere view using a Modified Azimuthal Equidistant projection centered at 100 degrees West. Rendered cleanly in about twenty minutes. If you don't want to build your own from raw data, Natural Earth Data is free and doesn't require an account. For a quicker pre-rendered option, NASA's Visible Earth gallery has satellite composites and some hand-drawn hemisphere maps you can grab at reasonable resolution. The Blue Marble images are 2012-era Landsat data, roughly one kilometer per pixel at the equator, which is plenty for web use but not precise enough for anything involving borders at small scales.
What most people get wrong about Western Hemisphere maps
The biggest mistake I see people make is assuming a simple polar or equatorial Azimuthal Equidistant projection is good enough for comparative analysis. It's not. In an Azimuthal Equidistant projection centered on the North Pole, distances from the center are correct, but areas near the edges compress wildly and shapes tear. For a Western Hemisphere view, you're pushing much of South America and eastern Russia toward the periphery, and the distortion makes the southern cone look squashed. This matters if you're trying to show relative landmass or travel distances. A better choice for general reference is theInterrupted Goode Homolosine. It sacrifices continuous area to reduce distortion across the whole hemisphere. The breaks run through the oceans, which actually helps here since the Atlantic and Pacific become the disruption zones rather than cutting through population centers. The trade-off is that it looks weird if someone isn't used to interrupted projections. I had a colleague pitch a client with a Goode version and the client thought it was a printing error because the oceans looked split. Took twenty minutes to explain it was intentional. For navigation-style thinking, a gnomonic projection centered around 75 West, 0 North puts the whole Western Hemisphere on a plane where great circle routes appear as straight lines. Useful for flight path visualization. Terrible for showing anything about land area or relative size. You pick the tool based on what question you're actually trying to answer, not the other way around.

Building your own when you can't find what you need
If the available maps don't meet your specs, making one in QGIS takes roughly fifteen minutes once you have the Natural Earth coastlines loaded. Import the 1:50m coastal polygons, switch the project CRS to a custom azimuthal equidistant projection, set the central meridian to 100 West and the latitude of origin to zero, then cluster the land polygons by hemisphere. Anything west of the prime meridian going westward to the antimeridian at 180 East stays. You can clip the extent to a circle and remove the Eastern Hemisphere pieces with a simple mask layer. Export as GeoTIFF or SVG depending on your output need. I once needed a version where Greenland showed up correctly positioned relative to Canada without being swallowed by the projection edge. The standard approach drops Greenland off the top of the frame because it sits above the typical western hemisphere bounds. My workaround was shifting the center point to 90 West, 45 North instead of the equator. This pulled Greenland into the main frame while keeping most of the Americas centered. The distortion on Antarctica increased, but that region was irrelevant to the client's use case anyway. It was a twenty-minute adjustment that saved me from explaining why a standard projection couldn't handle their request.
The limitations you should know about
Any single map of the Western Hemisphere is going to misrepresent something. Area, shape, distance, direction — pick three. The further you push a flat map to include both North and South America in full, the more distortion accumulates, especially near the antipodal edge around 80 degrees East longitude, which falls in the Indian Ocean but still affects how the map boundary behaves. There's no escaping this. If you need accurate area representation specifically, use a cylindrical equal-area projection and accept that the shapes will look stretched. If you need accurate shapes, use conformal and accept that areas will be wrong. For quick reference or decorative purposes, pre-made maps from sources like the CIA World Factbook or standard educational publishers are acceptable. They prioritize familiarity over accuracy, which is fine if that's what you need. But if you're working with geographic data or presenting to people who will question the numbers, building your own with a known projection gives you control over the distortion profile and lets you explain exactly what the map does and doesn't show. I keep a QGIS project file with the standard Western Hemisphere setup saved so I don't rebuild it from scratch every time. Takes about five minutes to spin up a new version with updated coastlines if Natural Earth releases a revision.
