Question

map projections
flat map represents 3 - d curved surface of a = map projection
projection is an entirely accurate representation.
cylindrical projection
meridians appear
equal space between parallel lines.
on a globe, meridians come together at
accurate near equator, distances & sizes distorted near poles.
form a - easy to locate positions.
good for small areas.
azimuthal projections
little distortion at point of contact - usually one of the poles.
spacing between parallels.
distortion in distance and direction.
great help in plotting
great circle appears as a straight line.
conic projections
touches the globe along one parallel of latitude
many neighboring conic maps make a projection.
reading a map
usually drawn with at the top, on the right, on the left, on the bottom
parallels run side to side.
meridians run from top to bottom.
indicates cardinal directions, n, e, s, & w.
symbols & map scales
map symbols are explained in the map, or key.
to be accurate, maps must be drawn to
scale: printed line represents unit of measure.
scale: 1:25,000 indicates 1 unit of distance on a map = 25,000 of the same unit on earth.
scale: \one centimeter is equal to one kilometer\

Brief Explanations

A flat map represents the 3 - D curved surface of a globe. No projection is entirely accurate. In cylindrical projections, meridians are parallel, they come together at the poles, and it forms a grid. Azimuthal projections have variable spacing between parallels and are useful for plotting great - circle routes. Conic projections touch the globe along a parallel of latitude and neighboring ones can make a polyconic projection. Maps are usually drawn with north at the top, east on the right, west on the left, south on the bottom, and a compass rose indicates directions. Map symbols are explained in the legend, and maps must be drawn to scale, which can be a bar scale, a ratio scale, or a verbal scale.
