Mapping Earths Surface Flashcards
Process in which map makers determine distances and elevations using instruments and the principles of geometry
Topography
Map makers can store, process and display data electronically
1 way computers have revolutionized map makers
Map makers can digitize data,
2nd way computers have rev. Mapmaking
3rd way comps have rev mapmaking
Automatically make maps that would take a person hours to make
Produce maps from many data sources, such as satellites and gps
4th way that comps reved mapmaking
GPS
Global Positioning System
A method of finding latitude, longitude, and the elevation of points on Earth’s surface by using a network of satellite
GPS
Pichus of earths surface made up of thousands of tiny dots called pixels
Satellite images
Map showing the surface features of an area using symbols to portray the land as if you were looking from above
Topographic map
To read a topographic map, you must understand the…
Map scale, the symbols, and the contour lines.
Represents the elevation, relief, and slope and connect points of equal elevation. Used to show elevation!
Contour lines
Change in elevation from one contour line to another
Contour intervals
Darker line than the others and are labeled with the elevation abuv sea level on round units
Index contours
Map designed to show distribution of geologic features. In particular, types of rocks
