A map, according  to one source, Jessica Karpilo, is  a representation, usually on a flat surface, of a whole or part of an area. The job of a map is to describe spatial relationships of specific features that the map aims to represent. There are many different types of maps that attempt to represent specific things. Maps can display political boundaries, population, physical features, natural resources, roads, climates, elevation (topography), and economic activities.

Maps are produced by cartographers. Cartography refers both the study of maps and the process of map-making. It has evolved from basic drawings of maps to the use of computers and other technologies to assist in making and mass producing maps.

Just had my independent subway experiences and indeed the New York City Map became a true and tested life saver.

Do the same fellow Newbies before you get lost in this City where everything looks similar but one wrong corner and you will really cry how to solve your mistake. A mistake which could have been easily remedied if you had a City Map. After all, all you have to do is go to a subway station. Go to a Metropolitan Transit Authority (MTA) employee, buy your Metro Card. Better have it loaded for one week ($2.75 times 7 = $19.25) unlimited so you will surely have all rides via subway train and buses taken care of by your Metro Card on an unlimited basis for one week.

For the Newbies, the map will tell you what train to take and how many stops before you reach your destination.

Others may grasp the extent of the Map’s use quickly but for others, it will be a day-to-day ordeal but a necessary one for your safety.
