You’re standing in the middle of a trail, phone dead, staring at a piece of paper that looks like a tangled mess of spaghetti. You call it a map. Your hiking guide calls it a topographic sheet. The historian in the library calls it a cartograph. Honestly, the terminology shifts depending on who you’re talking to and what exactly you’re trying to find. Looking for another name for map isn't just about finding a synonym; it’s about understanding the specific tool you need for the job.
Words have weight.
A sailor doesn’t use a "map" to cross the Atlantic. They use a chart. If you called it a map on a bridge of a container ship, the navigator would probably give you a look that says you’ve spent too much time on dry land. There is a fundamental difference between land and sea navigation that dictates the vocabulary.
When a map becomes a chart
Let's get into the weeds of the nautical world. A chart is arguably the most common "other name" for a map, but you can’t just swap them out whenever you feel like it. National Oceanic and Atmospheric Administration (NOAA) experts will tell you that while a map represents land features, a chart is a working document.
It’s meant for plotting a course.

You draw on it. You mark soundings, submerged wrecks, and the "set" of the current. It’s dynamic. Maps are generally descriptive, showing you where things are. Charts are functional, showing you where you can go without hitting a rock.
Interestingly, aviators also use the term aeronautical chart. If you’re flying a Cessna 172 at 5,000 feet, you aren't looking at a road map. You’re scanning a sectional chart. These are packed with "obstruction heights" and "airspace classes" that would make a casual driver’s head spin.
The artistic side: Cartographs and Planispheres
Maybe you aren't looking for a technical tool. Perhaps you’re thinking of those beautiful, hand-drawn pieces of art. In that case, cartograph is a term that carries a bit more prestige. It sounds fancy. It’s derived from the French carte and the Greek graphein.
Then there’s the planisphere.
This is a specific type of map that represents a sphere on a flat plane. Usually, when people use this word, they are talking about star charts—those circular things you rotate to see which constellations are visible in the night sky. It’s a bit of a niche term, but if you’re into astronomy, it’s the only word that fits.
I once met a collector who insisted on calling his 17th-century Dutch maps atlas plates. An atlas, as you probably know, is just a collection of maps bound together. The name comes from the Greek Titan Atlas, who was depicted holding up the celestial sphere. Mercator was actually the one who first used the name "Atlas" for a book of maps in the 1500s.
Technical jargon: From Plats to Orthophotos
If you’ve ever bought a house, you’ve dealt with a plat.
A plat is a specific type of map used in real estate and urban planning. It shows the divisions of a piece of land. It’s not "pretty." It’s a legal document. It defines where your property line ends and your neighbor’s starts, which is pretty important when you’re deciding where to put a fence.
In the world of modern technology and GIS (Geographic Information Systems), we see terms like orthophoto or orthomosaic. These are basically aerial photographs that have been geometrically "straightened" so that the scale is uniform. They look like pictures, but they function like maps.
Then there’s the topographic sheet, or "topo" for short.
Hikers live and die by these. Unlike a standard road map, a topo map uses contour lines to show elevation. It’s three-dimensional thinking on a two-dimensional surface. If the lines are close together, you’re in for a steep climb. If they’re far apart, it’s a stroll.
Digital shifts and the "Visualizer"
In 2026, we rarely even use the word "map" in isolation anymore. We talk about interfaces, layers, and geodata. When you open an app on your phone, you’re looking at a digital twin of the world.
Some tech circles prefer the term spatial representation.
It’s a mouthful. But it’s accurate. It acknowledges that the "map" is no longer a static thing but a stream of data points being rendered in real-time.
Strange and forgotten synonyms
History is full of weird words for maps. Have you ever heard of a mappa mundi? This was a medieval European map of the world. They weren't meant for navigation. They were more like encyclopedias of religious and classical knowledge. They often put Jerusalem right in the center and featured monsters in the "unexplored" corners.
Another one is portolan.
These were the "hacker" maps of the 13th and 14th centuries. Sailors used them to navigate the Mediterranean. They were covered in crisscrossing lines called rhumb lines, which helped mariners find their bearings using a compass.
Why the variety matters
Choosing the right word actually changes how people perceive your expertise. If you're talking to a surveyor and you ask for a "drawing," they might be confused. Ask for a survey or a site plan, and you’re speaking their language.

Basically, the "other name" depends on the medium and the mission:
- Sea/Air: Chart
- Real Estate: Plat or Site Plan
- Old/Artistic: Cartograph or Mappa Mundi
- Scientific: Spatial Dataset or Orthomosaic
- Stars: Planisphere
The word "map" is a catch-all. It's the "stuff" category. But as soon as you get specific, the language gets much more interesting.
Actionable steps for choosing the right map
Don't just grab any visual guide. If you're heading into the wilderness, ditch the "road map" and find a USGS Topographic Quadrangle. It provides the detail necessary for survival.
When dealing with legal property issues, don't rely on a Google Maps screenshot. You need a certified plat from your local county recorder's office. This is the only "map" that holds up in court.
If you are designing a website or an app, think in terms of spatial UI. Users don't want a static image; they want a "living" map that they can toggle.
Next time you're looking for a map, ask yourself: am I navigating, planning, or just admiring? The answer will tell you exactly which "other name" you should be using.
Go look at your local library’s digital archives. Search for "cartographic materials" rather than "maps." You’ll be surprised at the depth of what hides under the more formal labels. Sometimes, the best way to find what you need is to stop using the most common word for it.
