Which of the following do geographers use to compare a variety of spatial data by creating digitized representations of the environment by combining layers of spatial data, and creating maps in which patterns and processes are superimposed?
GPS
GIS
Scale
Maps
Pick the most accurate statement.
GPS locates places while GIS displays them.
GPS can only show locations but GIS provides a lot more information related to locations.
GPS shows one layer of data whereas GIS always shows multiple layers.
GPS does more than GIS as more people use GPS.
Vector data is easier to store on a computer as it takes less file space.
TRUE
FALSE
Lines of equal longitude are called ...............
Meridians
Parallels
Distortion
Stations
Globes provide a three-dimensional view of the Earth. They provide the most accurate view of the world, but have limitations in their use.
True
False
All world map projections create distorted images of the Earth to some degree. These distortions relate to size, shape, direction, and distance.
True
False
Why is it difficult to project the Earth onto a flat surface?
it distorts the sizes and shapes of the landmasses
the technology to do so does not exist
it cuts the Earth into 2 hemispheres
it's actually not the difficult
This is a Mercator projection map. Why is this map projection not be the greatest to use when determining land size?
Places at the poles, like Greenland and Antarctica, are extremely distorted in their size, appearing larger than they really are.
Africa appears too large on this map.
All the continents are smaller than they actually are.
Places by the equator are highly distorted and appear much larger than they really are.
The map shown here, called the Peter's Projection, does which of the following?
It shows the accurate distance between the continents.
It is used for marine navigation.
It shows accurate sizes of the continents.
Why do we use maps more often than we use globes?
Globes are bulky and not as easy to store.
Globes distort shape and size too much.
Globes are not around anymore.
In recent years, a GPS has taken place of these maps...
road maps
thematic maps
elevation maps
physical maps
What are this map's distortions?
land masses near poles are too large
