Maps

The Maps change every once in a while when they change names of things or find new places. The area covered on a map depends on its map scale. A map scale can be presented in 3 ways one way is in a ratio or fraction. Distance can be two points between an overlaid on the scale bar or to determine a distance on earths surface. projection is scientific method of transformation locations on a flat map. Spherical shape causes distortion when drawing it on a flat piece of paper. there is 4 types such as 1. shape of an area can be distorted 2. distance between points may become increased or decreased 3. relative size of different areas can be altered 4. direction between 2 points can be distorted. They can also look like mercator, Goode homolosine and Robinson projection.  Learning about maps is not my strongest thing. I usually don't understand how to work them thats why I usually use my device to use google maps when I don't know an address or a new area we are driving too. I am excited to learn more about the history of maps because they are updated but some are from along time ago so I wonder how they know when to update and what to add and what not to. Like what would be important to add and what is just extra information.
