Map Terms - A to C

Since everyone is back in school, we figured you were probably up to your neck in geography homework. We've put together a glossary of map terms, so now you have no excuse for getting lost in the hallway and finding yourself back under those warm blankets.

Axis - An imaginary line the Earth rotates around. When speaking about maps and globes it's the line that measurements are made from to determine a specific location.

Bar scale - This is that part of the map that looks like a ruler. It's a line that is used to measure distance on a map. The line is divided into units that are equivalent to the scale of the map. It is numbered so you know the distance of each mark from the zero mark on the line.

Base map - A map with all the important information about the Earth's surface - like landforms, drainage, landmark features and political boundaries. Most of them have labels or names. They come in a series and are used as a reference for thematic information. Examples of base maps include topographic and planimetric maps.

Bearing - Also known as direction. Bearings are determained by the direction (usually angular) from one position to another using geographical (land) or celestial (stars) reference lines. If the angle is measured clockwise from the north, then it is called bearing east. If it's measured counter-clockwise it is called bearing west. Bearings can be measured from True North, grid north or magnetic north. Bearings and headings mean the same thing except bearing is a fixed position and heading is the direction that an object moves.

Cardinal Direction - This is one way to give directions. Instead of saying, "Turn left at McDonald's, then go right at the gas station," cardinal directions use north, south, east and west. You would say, "Go west at the McDonald's and north at the gas station."

Cartesian coordinate system - Your teacher gives you a map of Mexico and tells you to find Mexico City. You won't have a problem if you know the Cartesian system. X measures the horizontal distance (across) and Y measures vertical distance (up and down). There are intersecting straight lines (called axes) that are all the same length. You can measure distance, area and direction by following two intersecting axes along a line parallel to the other axis.

Cartography - The art, science and technology of making maps. Accurate measurements, classification and much more are used to make visual models of our world. It used to be done manually but with today's technology, it's done on computers.

Central meridian - A line running north and south at the center of a map (or other design), which has been divided into squares so the map can be put into other dimensions. All the points along the line have the same longitude.

Compass - This is the instrument to have if you're ever lost. A magnetic needle on a round dial or card tells you where north is. Regardless of where you are, the needle always points north. A different kind of compass is always used for drawing and measuring circles.

Compass

Coordinates - A set of numbers on a map used to find the distance from a specific place, also known as the origin. In a Cartesian coordinate system, there's an "x,y" location or an "x,y,z" location (If the system is 3-dimensional). See Cartesian coordinate system.

I am very feminist and if you read my post you'll see how I feel So I read the post and it seems that it has almost nothing to say about ego. These are the only things I, at least, can get out of your post about feelings: ​1. The question: Do beauty pageants objectify women? 2. Your description of what way you are using the word 'objectify': Degrading a person to seem like a mere object ​3. Wanting to know everybody's opinion ​ ​That's it. I'm probably the only one here to bring up the subject about 'egoistical'. And since you are a feminist I will plainly assume that you agree with me on these girls in the pageant being of larger ego than usual. But your comment is slightly confusing and therefore I have no idea if you are angry with me or if you are telling me that you are agreeing with me saying that you feel that pageant girls are egoistic or something. But I know one thing: You feel badly about these pageants. If you would detail your comment more I would be relatively satisfied and probably even have a full answer. On the other hand, thank you for recognizing my comment, I was glad to hear your reaction, even though it was somewhat confusing, and I hope you have a good continuation of the day, m'am. :) No no, sorry about it confusing. What I meant was I disagreed with the egotistical part and wanted you to know I was a pageant girl and I wasn't that way, however I was too lazy to retype how I felt about this subject so I directed you to my post before cx Sorry. My post is in favor of beauty pageants, I've realized lately that I can't portray what I'm trying to say in a non-confusing way to other people so I guess I'll try and clarify. I feel beauty pageants are helpful to the girls in them, I had been bullied harshly but my mother said everytime I was on stage I seemed to have some confidence which I didnt have any other time. All Im really saying is people judge pageants too quickly without really realizing the deeper meaning behind them, I was just saying it from a beauty pageant girls mind
