The concept of scale the scale of a map is the ratio between distances on the map and corresponding distances in the real world o if a map has a scale of 1:50,000, then 1 cm on the map equals 50,000 cm or 0.5 km on the Earth's surface the use of the terms "small scale" and "large scale" is often confused, so it is important to be consistent o a large scale map shows great detail, small features representative fraction is large, e.g. 1/10,000 o a small scale map shows only large features representative fraction is small, e.g. 1/250,000 the scale controls not only how features are shown, but what features are shown o a 1:2,500 map will show individual houses and lamp posts while a 1:100,000 will not different scales are used in different countries o in the US, 1:100,000 is the largest scale at which complete coverage of the continental states exists, but there is limited coverage at 1:62,500 and 1:24,000 o in the UK, there is complete coverage at much larger scales (1:1,250 to 1:10,000) Map projections

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
