53. Bathymetry Map

This topographic (hypsometrical) map contours the depths of water bodies (i.e. ocean floors). Its contour intervals are called isobaths and these maps are often used for deep sea navigation and the study of past ocean floors. They are obtained through depth sounding.

52. Hypsometric Maps

Source

Hypsometric map gives information on the 'relief' of earth's surface (elevation) using contours or shading such as the map on the left.

51. Ideogram

Source

Ideograms are cryptic graphic symbols that represent ideas about place. The image to the left is a map of a gene. Each color (strip of color) represents a different gene. This ideogram allows the genes to be mapped out on the chromosome because they can't be observed. It also allows geneticists to keep track of genes and see how they translocate or "move" to another during replication.

50. Isoline Map

Isoline maps and contour maps are synonymous. They use intervals to depict change in the measured variable. This is an isoline map of the January temperatures in Australia. According to this isoline map, the difference between each line is 10deg F.

49. Topographic Map

Source

Topographic maps such as this one represent the natural features of a land mass. As you can see, Africa is mostly desert, flat terrain, and jungle. Maps such as these use a variety of methods to convey information (i.e. color, contouring, etc.).

48. Line Graph

Line graphs can serve as maps for continuous data such as sound. This graph allows us to see that sound travels as a wave and not like individual particles. It also lets us know the frequency of the wave; according to this graph this is a sine wave.

47. Magnetic Resonance Imaging

MRI's are also a form of remote sensing as well as mapping. They allow healthcare professionals to observe and map out the inside of the human body in a non invasive manner. They serve as maps because many doctors would not be able to treat their patients without images such as these. Thus serving as navigational tools for physicians.
