What is the main purpose of map projections?

• To show the Earth's surface in its true proportions
• To draw the Earth's surface on a cone
• To create a 3D model of the Earth
• To move the image of the Earth's curved surface onto a flat surface (correct)
• What type of map projection is the Mercator projection?

• Azimuthal projection
• Equal-area projection
• Cylindrical projection (correct)
• Conic projection
• What is a characteristic of an Azimuthal projection?

• It projects latitude and longitude lines as straight lines
• It touches at each line of the longitude but one line of the latitude
• It moves the contents of the globe onto a flat plane (correct)
• It shows the area between the latitude and longitude lines the same size as that area on a globe
• What is the purpose of remote sensing and satellites in mapmaking?

Study Notes

Mapping the Earth's Surface

• Maps are 2D representations of the Earth's 3D surface, which can lead to distortions in shapes and sizes of landmasses and oceans.

Map Projections

• Map projections are methods used to move the image of the Earth's curved surface onto a flat surface.
• No map projection can show the surface of a sphere in correct proportions.

Types of Map Projections

Cylindrical Map Projection

• A cylindrical projection is made by moving the contents of the globe onto a cylinder of paper.
• It projects latitude and longitude lines as straight lines.

Mercator Projection

• The Mercator projection is a type of cylindrical projection.
• It is accurate near the equator but distorts areas near the North and South Poles.

Conic Projection

• A conic projection is made by moving the contents of the globe into a cone.
• The cone touches each line of longitude but only one line of latitude.

Azimuthal Projection

• An azimuthal projection is made by moving the contents of the globe onto a flat plane.

Equal-Area Projection

• An equal-area projection shows the area between latitude and longitude lines the same size as on a globe.

Modern Mapmaking

• Remote sensing and satellites are ways to collect information about something without physically being there.
• Remote sensing and using radar are other methods of collecting information.

Research and Comparison

• Researching a specific map projection and its distortions can help understand the limitations of mapmaking.
• Comparing and contrasting different types of map projections can highlight their strengths and weaknesses.
• Understanding distortions can affect the accuracy of the map for different purposes.
