Get All Weeks GIS Data Acquisition and Map Design Coursera Quiz Answers
In this course, you will learn how to find GIS data for your own projects, and how to create a well-designed map that effectively communicates your message. The first section focuses on the basic building blocks of GIS data, so that you know what types of GIS files exist, and the implications of choosing one type over another. Next, we’ll discuss metadata (which is information about a data set) so you know how to evaluate a data set before you decide to use it, as well as preparing data by merging and clipping files as needed.
We’ll then talk about how to take non-GIS data, such as a list of addresses, and convert it into “mappable” data using geocoding. Finally, you’ll learn about how to take data that you have found and design a map using cartographic principles. In the course project, you will find your own data and create your own quantitative map.

Week 1 Quiz Answers
Quiz 1: GIS Software needed for this course

Q3. Which of the following is a basic element of topological relationships?
- coordinate transfer
Q4. Which of the following is a component of a geodatabase?
- feature class

- all of the above
Week 2 Quiz
Q1. A detailed description of the data contents of a database is called a:
- data synopsis
- data guide
- data thesaurus
- data dictionary
Q2. Which of the following is not an example of metadata?
- latitude and longitude coordinates
- scale used to create the data
- contact information of data supplier
Q3. When the overlapping area between two feature classes is identified and stored in a new file where the attributes of only one of the feature classes is maintained, this function is called:
Q4. Which of the following best describes the Dissolve tool?
- removes all boundaries shared between adjacent polygons
- removes all boundaries shared between polygons, regardless of their adjacency
- removes all boundaries shared between adjacent polygons that share the same attribute
- removes the attributes from a table
Q5. True or false: when adding x,y data from non-GIS file, it is not necessary to specify a coordinate system.
Week 3 Quiz
Q1. The ecological fallacy states that:
- it is correct to assign an average value for an area to an individual, if it is done anonymously
- it is not possible to maintain viable wildlife habitat in an urban environment
- it is incorrect to assign an average value for an area to an individual
- two polygons must not occupy the same location
Q2. Which of the following best describes the process of geocoding?
- the process of transforming data such as postal codes or address information into location information (i.e., coordinates)
- the process of encoding a file containing geospatial information
- the process of encrypting geographic information to ensure privacy for individuals. An example would be reporting census data at the level of census tracts rather than at the individual level
- the process of transforming coordinates into address information
Q3. In which scenario would you not use geocoding?
- You are creating a map of all the trees in your neighbourhood. You obtain the latitude and longitude coordinates of each tree
- You are creating a map of cafes in your city. You have obtained a list which includes each cafe’s address.
- You run a small store, and collect your customers’ postal codes as they make their purchases. You wish to determine the neighbourhoods your customers are coming from, and need to determine where they live based solely on their postal codes.
Q4. Address locators can be used to geocode which of the following?
- postal/zip codes
- place names
- all of the above
Q5. When geocoding in ArcGIS, the style:
- guides the address locator to look for certain types of data
- none of the above
- specifies how the output will look
- allows you to vary the method according to personal preference
Week 4 Quiz
Q1. Which of the following is/are appropriate ways to improve legibility? (there is more than one correct answer)
- using “call-outs” to label features
- adding halos around label text
- legibility can only be improved by reducing font size so that labels fit within blank areas. It is better to have very small text so that more features can be labeled.
- the GIS software will automatically optimize legibility
Q2. It is not usually necessary to use built-in alignment tools in ArcMap, as the human eye is good at detecting small errors in alignment.
Q3. The typeface used for the words in this question are of which type?
- sans serif
Q4. If the actual distance between two points on the ground is 1 km, what is the distance between these same two points on a map that has a scale of 1:100,000?
- 1 cm
- 10 cm
- 100 cm
- 1000 cm
Q5. Which of the following would normally be considered to be most importat with respect to visual hierarchy?
- mapped area
Q6. Which of the following is the best example of a large-scale thematic map?
- a map of Central Park in New York City, showing locations of picnic areas
- a map of the United States showing political boundaries, vegetation, elevation, and towns
- a map of North America showing temperatures for Tuesday, October 22
- a topographic map of your neighbourhood showing a variety of different features such as roads, buildings, parks, and elevation
Week 5 Quiz
Q1. Which of the following is not important to consider when creating a choropleth map of quantitative data?
- the size of the dots for the dot density pattern
- classification scheme
- whether to show counts (total numbers) or derived values (for example, normalized by the size of each area mapped)
- color scheme, and how it affects visual hierarchy
Q2. The term “choropleth” comes from the Greek word “chloro” meaning “green”
Q3. Which of the following colour models is often used for printing, and is a subtractive model?
Q4. Which of the following elements of the Hue – Saturation – Value (HSV) colour model would you need to adjust to show geographical variations in temperature ranging from blue for cold regions to red for hot regions?
Q5. For which of the following level(s) of measurement is it possible to have a negative value? (there is more than one correct answer)
Q6. True or False: when mapping population, it is better to map counts rather than densities, unless all regions are exactly the same size. This is because smaller areas are likely to have higher densities.
Q7. Which of the following is an example of a derived value?
- fertilizer used per square meter
- temperature in each ecoregion
- population in each census tract
- total crop yield in each field
Week 6 Quiz
Q1. Which of the following is important when creating a dot density map (for example, of population density by census tract)
- it is important to normalize the population values by the area of each census tract
- it is important to consider the size of dots so that they are neither too sparse nor too dense in any particular area
- it is important to determine the colour saturation levels used for each dot such that darker dots represent higher values
- it is important that each dot represent a single person when mapping population density
Q2. Appearance compensation:
- increases colour contrast to improve map design and visual communication
- is needed for both lengths and areas when reading symbols on a map
- shrinks the sizes of proportional symbols because people overestimate the correct values associated with symbol areas
- exaggerates the sizes of proportional symbols because people underestimate the correct values associated with symbol areas
Q3. The “Ebbinghaus illusion”:
- is illustrated by the increase in distortion away from the Equator
- can be lessened by adding lines between symbols
- can be caused by using too many similar line patterns to fill adjacent areas
- is caused by two similar values being placed in different classes, exaggerating differences
Q4. On a contour map, lines that are close together represent:
- flat area
- steep slope
- gradual slope
Q5. A cartogram where the boundaries of each mapped area are touching is referred to as:
- an “exploded” view
