, Laboratory Honor Statement
Cheating or plagiarism of any kind will not be tolerated in ESS 101.
This includes copying answers from a friend or classmate, copying
answers verbatim found on the internet or other literary sources, or
copying any work that may answer the question being asked. Make
sure you always use your own words when answering the questions in
the homework and cite appropriate references if you use them to help
you answer the question. Anyone caught violating the academic code
of conduct (https://www.washington.edu/cssc/for-students/academic-
misconduct/) will receive a “0” grade on the assignment, and if the
conduct is deemed egregious, reported to the UW Academic
Misconduct representative.
I acknowledge that I have carefully read and understand the above
statement regarding the consequences of cheating and plagiarism, and
promise to complete my work in this class with honesty and integrity.
Answer "True" below supporting your acknowledgement.
Correct! True
False
Learning Goals
By completing this lab, students will gain a deeper of understanding of
how:
Maps are used to convey important information on the Earth’s
surface
The geographic grid (latitude and longitude) is used to describe
location on a map
To read topographic maps and use the data for landscape
analyses
, To construct a topographic profile and use it to interpret geomorphic
processes
To use aerial photographs and LiDAR imagery to interpret
landscapes
Introduction
Geoscientists utilize many different techniques to study the Earth, and
many of these techniques do not always involve fieldwork or direct
sampling of the Earth’s surface. Before a geoscientist completes work
in the field, s/he will often review maps or remote images to learn about
the study area. For example, consider a geoscientist who is assessing
the landslide hazard for a proposed housing development near a steep
slope. S/he can gain valuable insights about the local rock type and
nearby geologic structures by looking at a geologic map. Additionally,
s/he could use aerial photographs to study local topography and
identify evidence for past landslides or erosion. Geoscientists also
often record their field data on maps so that it can be interpreted within
a spatial context and shared with other geoscientists or the general
public.
In today’s lab, we will explore map-reading, aerial photo interpretation,
and remote sensing techniques that are utilized by geoscientists to
study the geologic landscapes and processes operating at the Earth’s
surface. Many of these techniques will be integrated into future
laboratory exercises.
History of Maps
A map is a two-dimensional representation of a portion of the Earth’s
surface. Civilizations have used maps for over three thousand years;
the earliest known map was made by the Babylonians in the 6th century
BCE. The earliest maps were largely drawn to denote place names and
general directions, often neglecting accuracy and scale. Figures 1-1A
and 1-1B illustrate the simplicity of these early maps1.
, Figures 1-1A and 1-1B: Babylonian map of the world (Fig. 1-1A) drawn on a clay tablet
circa 500 B.C. The map represents ancient Babylon, the Euphrates River and
surrounding ocean, which today comprises modern Iraq. Fig. 1-1B is a representation of
an original Roman map entitled, Orbis Terrarum, drawn by Marcus Vipsanius Agrippa in
20 A.D. The ancient Roman map shows Europe, Asia and Africa surrounding the
Mediterranean Sea.
Following the decline of the Roman Empire, near the end of the 5th
century A.D., innovation and advancement in cartography declined for
almost 1000 years until the start of the Renaissance Period in the late
14th century. During the Renaissance Period, the Age of Exploration
and Discovery brought about a need for increased accuracy in maps,
particularly for navigational purposes as global trade and colonization
increased. Figure 1-2 shows a world map, originally published by the
Flemish cartographer Gerard Mercator in 1595, and subsequently
published in Henricus Hondius’ Atlas in 16332. Such maps provided
valuable navigational information, such as latitude and longitude
coordinates and the seasonal position of the overhead sun for
seafaring explorers and traders.
