Explain how mapmakers use computers to store and display map data.

All of the data used in computer mapping must be written in numbers . The process by which mapmakers convert the location of map points to numbers is called digitizing. These numbers are stored

What sources do computers use to make maps?

Computer use data from satellites and Global Positioning

Which map is best to show one continent?

Conic Projection because its can show one continent very well

Conic

Distortion Little distortion if area is limited and latitude curved and longitude is straight

Equal-Area

Distortion shapes of landmasses near the edges of the map and lines of longitude and latitude Latitude straight, longitude curved

Mercator

Distortion toward and lines of latitude and longitude straight and parallel lines

method for finding latitude, longitude, and elevation of points on Earth's surface by using a network of satellites.

Globe Positioning

Circle the letter of each sentence that is true about the prime meridian.

It makes a half circle from the North Pole to the South Pole.

Circle the letter of each sentence that is true about an equal-area projection.

Landmasses near the edges are distorted. Sizes of land masses are shown correctly.

What kinds of features are shown by Landsat images?

Landsat images show what covers land-surface plants, soil, rock and water and snow and ice. Large, human made features such as cities are also visiabl

________________________ satellites collect data about a strip of Earth's surface. → The satellites relay the data back to a(n) 2. ________________________ on Earth. → The data is made into a picture by a(n) 3. ________________________. → When the image is printed, it is made up of thousands of tiny 4. ________________________.

Landsat, Station, computer, pixels

Circle the letter of each sentence that is true about latitude.

Latitude measures distance in degrees north or south of the equator. All lines of latitude are parallel to the equator.

Circle the letter of each sentence that is true about a Mercator projection.

Lines of longitude meet at the poles. Sizes of landmasses are changed.

Circle the letter of each sentence that is true about longitude.

Longitude measures distance in degrees east or west of the prime meridian. Lines of longitude cross lines of latitude at 45° angles.

Which map is most useful in finding direction?

Mercator Projection

Can a contour line on a topographic map connect a point with an elevation of 100 feet to a point with an elevation of 110 feet? Explain why or why not.

No it needs to be equal elevation

Explain how the types of mountain landforms are related to one another.

They all work in a system or a range and can have different elevations though.

How is a plateau similar to a plain?

They are both flat or smooth on top

How could a person who snow skis or hikes use a topographic map?

They can see the elevation and show were the hills

Topographic map

What are some of the physical and human-made features that map symbols can represent?

Typography and features on earth surface

How do businesses and governments use topographic maps?

You can design highways and plan a route for a highway over a mountain pass.

Why might you use a topographic map if you were planning a bicycle trip?

You could see if your trip would be flat or hilly.

How does a coastal plain differ from an interior plain?

a coastal plain has lower elevation and low relief

What is a map projection?

a framework of lines that helps in transferring points on Earth's three-dimensional surface onto a flat map

What is the longitude of the prime meridian?

at 0 degrees and each hemisphere is measured up to 180 degrees

How do mapmakers use computers?

can store , process and display map data electronically

Contour Interval

change in elevation from contour line to another contour line

Contour Line

contour line

The change in elevation from one contour line to the next is called the

counter interval

connects points of equal elevation on a topographic map.

counter line

The units scientists use to measure distances around a circle are

The process by which mapmakers convert the location of map points to numbers

digitizing

The process by which mapmakers convert the location of map points to numbers for use in computer mapping

digitizing

What do V-shaped contour lines indicate when they point downhill? When they point uphill?

downhill indicates a ridge line and uphill indicates a valley

How close the contour lines are is an indication of an area's

elevation

the height above sea level of a point on Earth's surface

How can index contours be identified?

lines are darker
