about countries or specialized
topics. Data and topics include,

Let’s Use An Online Atlas
Visit the National Atlas at
www.nationalatlas.gov .
1. Click on “Geology.” Choose “Geologic Maps.”
Write a brief description of the map that
appears.
2. Return to www.nationalatlas.gov . Click on
“Potentially Active Volcanoes.” Follow the
directions to find those in California. What is
the name of the potentially active volcano
nearest to Fresno?
Geographic regions or areas of interest are separated from
one another by boundaries. Boundaries can be lines like
those that separate counties and states on road maps.
Colored blocks can also serve as boundaries as with the
map shown below.
Let’s practice: What type of boundary might the blue and red
blocks of color represent on this map? Hint: the map might
be seen in your senior government class.

Cartography is the science of mapmaking.
It includes acquisition, presentation, and
use of data.
Let’s Practice: Be the Cartographer
Draw a map that shows the route you take to get from
your house to school. Provide at least four details that
would help someone to know the route whether or not
he/she had ever gone that way before.
Distance is the extent or amount
of space between two things,
places, points, or lines.
Let’s Practice!
Answer the following questions using the map
on the next slide:
1. What crucial piece of information is
included that helps you find the distance
between Fresno and Selma?
2. What is that distance in miles? In
kilometers?
3. What is the approximate distance between
Fresno and Madera?

A map feature is a visual
representation of real-world data. A
variety of features can be included
on a map. Some common features
are:
Cities
 Roads
 Water Features (blue creeks, rivers, lakes)
 National parks (often green)
 Restaurants (often represented by a fork and
knife)
Let’s Practice!
Identify two special features on the following
map. What do you think they represent?

City Center, Buenos Aires, Argentina

This system of 24
satellites can be
used by anyone
with a G.P.S. unit
to calculate their
position on the
Earth’s surface to
within a few feet.
Let’s Practice!
Go online and find four
different G.P.S. units &
name:
• the manufacturer
• 3 product details
• common uses
• a sale price for each
California is rich in resources. It is also rich in the
potential for damage due to natural hazards like
earthquakes. Cartographers provide maps of these
hazards as references for the public.
Let’s practice!
Look at the map on the next slide. Answer
these questions:
When was the map created?
1)How many earthquakes had been measured
within an hour of the map’s creation?
2)Approximately what magnitudes were the
two strongest earthquakes that occurred near
Fresno within a week of the map’s creation?
3)According to the data on the map, citizens in
what areas of the state were most likely to
have felt an earthquake during the week
leading up to the map’s creation?

Contour line that is accentuated in thickness and is
often labeled with the appropriate measure of elevation.
Index contours occur every four or fifth contour
interval and help the map user read elevations on a
map.
Let’s Practice:
The Contour Interval on the following map is 20 feet.
What is the elevation of the lake?

of the National
Park Service”
His cartographic
work made a
lasting and
profound impact
on our nation and
culture.
Let’s Practice!
Go online and find two additional individuals
whose cartographic contributions impacted the
study of our world in a lasting way. Describe
their work and its impact.

Photos taken from aloft provide a new perspective from
which we can view our world.
KAP is both a hobby and scientific method of collecting
remotely-sensed images for fun and science!

Latitude is the distance north or
south from a point on the
Earth’s surface to the equator.
 Longitude is the distance of a
point to the east or west of the
prime meridian.

Each is represented by lines that
form a grid over a map.
 Positions on the grid are
identified as East/West and
North/South coordinates.

1) What point is
located at 14’
N and 45’ W?
2) What are the
coordinates of
point C?
3) What are the
coordinates of
point F?

Let’s Practice!
Maps are visual representations of data
Traditional maps are two-dimensional.
Some are hand-drawn, others are digital.
Some digital maps are even threedimensional
Many types of maps: topographic, political,
road, weather, traffic, Bigfoot sightings, and
more!

1) Name 2 ways that this map differs from a road
map:
2) Name 3 features on this map that are ALSO
found on road and topographic maps:
► Object-based
data is data on a map in which one
feature represents one real-world object (such as
a hotel, a gas station, or a volcano).
► Maps that are created for travel and tourism
purposes often supply users with object-based
data.

Four-sided area, bounded by
parallels of latitude and meridians
of longitude used as an area unit
in mapping.
► Quadrangles often illustrate
the geographic data of a large
land area.
►
► The
process of obtaining data about an area,
while remaining a great distance from the
location.
► Common tools used in Remote Sensing:
 Satellites
 Kites (KAP) and Blimps (Blimp Aerial
Photography)
Let’s Practice!
This image was taken by the
Landsat satellite. It is a view of
Mount St. Helens, after its
eruption in 1980.
1)Name 1 similarity between this
Landsat image and a topographic
map.
2)Name 1 difference between this
Landsat image and a map of your
choice.

Maps must, by necessity, be smaller than the area they represent.
A map’s scale is a ratio of the distance on the map as it compares to
the actual distance that the map is representing.
An example of one such ratio is 1:24,000 (one unit of distance on the
map represents 24,000 of the same units of distance on the Earth).
Other examples of map scale might be: 1 inch = 1 mile or 1 inch =
2,000 feet.
Let’s Practice!
►A
map’s scale is 1 inch = 75 miles. The
distance between Town A and Town D is 3.5
inches. How far would one have to drive to
travel between the two?
►A
map’s scale is 2 cm = 15 km. The distance
between Elephant City and Giraffe National
Park is 8.75 cm. What is the actual distance
between these two locations?

According to http://www.usgs.gov/aboutusgs/
The Mission of the USGS is that it “serves the Nation by providing reliable
scientific information to describe and understand the Earth; minimize
loss of life and property from natural disasters; manage water,
biological, energy, and mineral resources; and enhance and protect
our quality of life.”
The Vision of the USGS is that it “has become a world leader in the
natural sciences thanks to our scientific excellence and responsiveness
to society's needs.”
This governmental department supports the study of: Biology, Geology,
Geography, Water, and Geospatial Data.
Let’s Practice!
Go to: www.usgs.gov. Find the box titled
“Science Topics.” Choose three of the topics
and:
1. Write the name of the topic.
2. Browse the topic and write down three
types of data that the USGS provides for
each.
3. Click on the “Education” tab. Name 1
resources that is available to secondary
schools.

Maps provide us with a view of our world that is different
than the one we see every day.
They condense features down into a manageable size. How
much easier is it to imagine yourself hiking into the Grand
Canyon when you look at a map than when you look at
this image?
Different perspectives can
be gained through use of
both topographic and
aerial ‘views.’
Let’s
Practice!
Compare and contrast Image A with Image B:
1) What do you think the image shows?
2) What type of image might each be? (Hint:
None are still photos).

Image A

Watershed
(1) The entire geographic region supplying water
to a drainage basin, river, or lake.
(2) An area of land that drains naturally into a
stream or other waterway.
(3) Water usage issues affect:
(1)
(1)
(2)
Daily lives & associated
activities
Agriculture production
Biodiversity

Let’s Practice!
Go to www.google.com. Type: Fresno AND “freshwater
sources” into the search. What
are two sources of freshwater?
2) Look at this image. The white
region is the snow-covered
Sierra Nevada Mountains. The
green is the Central Valley. The
blue is…?
3) The brown on the right is the
eastern edge of California and
western Nevada. Why do you
think the Central Valley remains
green while this area is brown?
(Remember: they both have

snowy mountains nearby.).
