Terms in this set (33)
Who made an early breakthrough for the science of epidemiology?
The study of things that affect a population's health.
Simplified image that is a model of part of the earth's surface.
Special kind of map that shows the earth's surface as it appears from space.
What are mapmakers called?
What is the most important great circle (latitude line)?
What are lines of longitude also called?
The latitude and longitude used to locate a point on the globe
Defines all of the symbols and colors used on the map.
Because you can't flatten a sphere without distorting it.
Why is every two-dimensional map of the earth's surface slightly distorted?
The transfer of geographic information on a 3D globe onto the 2D surface of a map.
Plane, Cylinder, Cone
What three shapes do cartographers use for map projection?
What kind of projection is it when the projection is on the equator?
What kind of projection is it when the projection is on a pole (north pole or south pole)?
What kind of projection is it when the projection is between the equator and a pole?
Robinson World Map
What map is typically used in textbooks and wall maps?
Map that shows names, boundaries, and shapes of countries, states, counties, cities, and towns.
Map that focuses on names, symbols, and locations of man-made and natural physical features, such as roads and highways, streams, lakes, coastlines, and oceans.
Map that displays elevation and landform information, usually indicated by special symbols, called contour lines, or by landform shading.
Shows elevations on the map above some standard height, such as sea level.
A map that displays certain kinds of related information to produce a unified theme.
What type of map projection is being displayed?
Geographic Information System
What does GIS stand for?
Why does a GIS produce thematic maps?
Point Data Type
Identifies specific locations
Line Data Type
Represents features with length
Polygon Data Type
Shows features that cover an area
Multiple Thematic Layers
What feature of GIS maps sets them apart from standard maps?
What is the best way to collect geographic data over a large area?
What is the main way to collect geographic data of the ocean floor?
You can't show everything without distortion.
Explain why a map is simply a model of part of the earth's surface?
Large-Scale- shows a small part of the earth with lots of detail.
Small-Scale- shows a large part of the earth with less detail
What's the difference between a large-scale and a small-scale map?
What is more effective for complex analysis than standard maps because layers of thematic data can be displayed as needed?
