Which of the following GIS applications is LEAST likely to improve delivery efficiency?
1) A typical drive-time map for flower delivery showing a central point surrounded by a series of concentric circles
2) A drive-time map for pizza delivery with isochrones taking into account the true road network
3) A road conditions map showing real-time traffic flow and obstacles
4) A GIS that calculates the optimal routing plan for a property inspector, such as that travel time is minimized.
Answer: (1)
A typical drive-time map for flower delivery showing a central point surrounded by a series of
concentric circles would assume an as-the-crow-flies route to each location, ignoring the true road
network. The other three options are all more likely to improve delivery efficiency.
The process of viewing only the GIS map layers that satisfy your particular needs is known as:
1) a selective query
2) unlocking the information
3) a spatial query
4) overlay operations
Answer: (1)
The process of viewing only the GIS map layers that satisfy your particular needs is known as a
selective query.
Selecting all properties within a 3km radius of an popular shopping mall and then comparing their assessed values with data about sale prices in an example of a(n):
1) point buffer zone analysis
2) line buffer zone analysis
3) area buffer zone analysis
4) None of the above
Answer: (1)
Point buffer zone analysis is the analysis of all features that exist within a particular distance of a point,
in this case a shopping mall.
Your client is a young urban professional looking to buy a house. To determine the optimal area, you have created a map that combines information on the average of the population in several neighborhoods, with the average household income. This is an example of:
1) a buffer
2) an overlay operation
3) a selective query
4) thematic mapping
Answer: (2)
By combining layers of useful information, you have determined an area that has both a lower average
age and a higher average household income. This is known as overlay operations

Which of the following regarding attribute information is FALSE?
1) an attribute is any piece of information about an abject that can be stored in additional to its geographic properties
2) Numerical referencing or coding systems prevent all users from identifying specific features with complete certainty
3) GIS may allow users to view data in tabular form without any maps, graphics, or geographical representations
4) A selective query allows users to view just those particular map layers that satisfy given criteria.
Answer: (2)
Numerical referencing or coding systems allow all users to identify specific features without any
uncertainty.
The process of changing how an object is depreciated on a map depending in its attributes is known as:
1) thematic mapping
2) spatial querying
3) buffering
4) attribute modification
Answer: (1)
The function of changing how an object is depicted on a map depending on its attributes is known as
thematic mapping.
Using GIS to calculate the optimal routing plan for a property inspector, such that travel time is minimized, is known as:
1) in-car navigation
2) network analysis
3) impact analysis
4) locational analysis
Answer: (2)
A benefit of network analysis is the ability to calculate drive-times and can be used to build complex
navigation systems, or simply for optimizing property inspection routes.
Which of the following is true with regards to multi-user GIS systems?
1) a disadvantage of public access is that GIS development and maintenance costs can be spread over a larger base.
2) The duplication of effort in muti-user systems makes them cost-prohibitive
3) Different data formats can make it difficult to share data
4) All of the above are true
Answer: (3)
A requirement of multi-user systems is being able to share data, and this can prove difficult. Option (1)
is false, because a wider cost base is an advantage of public access. Option (2) is false because
multi-user systems attempt to reduce duplication of effort
Image on lesson 9 MC question 12 is an example of :
1) computer aided design
2) a contour map
3) a choropleth map
4) AM?FM
Answer: (2)
A contour map uses lines to show locations that have the same attribute value, such as elevation in this
example.
The map on lesson 9 MC question 13 is an example of a:
1) topographic map
2) contour map
3) choropleth map
4) three-dimensional map
Answer: (1)
A topographic map shows physical surface features, such as roads, rivers, and buildings.
The map on lesson 9 MC question 14 is an example of a:
1) topographic map
2) contour map
3) choropleth map
4) three-dimensional map
Answer: (3)
A chloropleth map uses shading or colour to highlight common areas, in this each value range.
For a GIS map with shows neighborhoods and educational institutions, which of the following is true:
1) a line buffer is used to highlight the locational advantages of institutions by neighborhood
2) adding layers allows you to focus the GIS to help you with your specific research questions
3) this choropleth map isolates political influences and socioeconomic status
4) This map used 3D to illustrate elevation and topography
Answer (2)
A key benefit of GIS is that the analyst can add layers for the specific research questions of interest.
Here, the map displays educational institutions by neighbourhood. Option (1) is false because there is
no line buffer specified and locational advantages are not necessarily highlighted. Option (3) is false
because this is not a chloropleth map (which would use shading or colour to highlight common areas)
and it does not directly isolate political or socioeconomic information. Option (4) is false because this
is not a 3-D map.
If you were completing an environmental impact analysis for a proposed industrial development, you might use GIS to:
1) create 3-D landscape images of important sites
2) add a layer showing optimal drive-times for shoppers
3) integrate with assessment data to verify appraisal ratios and census data to identify demographic information
4) do all of the above
Answer: (1)
It may be helpful for your environmental impact analysis to have 3-D landscape images of important
sites. This GIS program allows this capability. Option (2) is incorrect because optimal drive-times are
not likely a focus of this type of study, and this is not a capability of this software. Option (3) is
incorrect because it is unlikely you would need ratio information for this study, and it is doubtful that
this data could be integrated into this program.
If you were completing a market report for a shopping centre in Prince George, you might use this GIS to:
1) create road maps highlighting key competitors
2) create satellite maps highlighting site attributes of the shopping center
3) search the city and region for related businesses
4) all of the above
Answer: (4)
You may use the features of this GIS to carry out all of the actions noted, as each of these could be an
important aspect of a market research report for shopping centre.
Which of the following GIS features is LEAST likely to be used by an assessor?
1) ratio analysis
2) sale verification
3) real-time vehicle tracking
4) Permit analysis to highlight need for inspections
Answer: (3)
Options (1), (3), and (4) are all examples of how assessors can benefit from the use of GIS. Real-time
vehicle tracking is more likely to be helpful for transportation organizations or emergency services.
Which of the following explains how an appraiser might affectively use GIS?
1) highlighting neighbourhood boundaries by overlapping property values, traffic volumes, and commercial uses.
2) Isolating comparable by viewing a map of recent neighborhood sales, highlighting property value and building age.
3) Applying change detection software to identify reclaimed harbour labor
4) all of the above
Answer: (4)
All three of the options are examples of how appraisers might use GIS in valuation work.
An appraiser in Toronto is working with GIS software on her personal computer. She downloaded locational data from several web sources, but the software is unable to interpret the data format and she cannot build this data into GIS. This is an example of a problem with:
1) interoperability
2) overlay operations
3) inadequate isochrones
4) none of the above
Answer: (1)
The ability to work with a variety of web-based datasets in a common format is a challenge facing GIS.
This is called interoperability.
What are the key elements needed to create GIS?
A Geographic Information System (GIS) is created through the integration of data, people, hardware,
software and methods (applications). GIS is all about taking advantage of the visual power of maps by
incorporating different types of data within user friendly systems to create dynamic and interactive
maps.
In what ways does a geographic information system offer a more powerful tool than conventional maps?
A GIS displays location elements like map, but also stores attribute information about objects on the
map. One of the key advantages of GIS over conventional maps is the ability to layer information.
When compiling a conventional map, one has to draw a balance between displaying as much information
as possible to make the map useful without adding so much detail that it becomes cluttered and
confusing. With GIS, this problem is removed – many different layers of information can be added, and
shown in different combinations and in a different order, depending on the particular message to be
conveyed. By switching different data layers on and off, the user can create many different views for
the same location.
What is a thematic map? Provide an example
Thematic maps use colours and shading of areas to display information related to location. For
example, a map of parliamentary constituencies shaded in different colours can show the number of
seats held by different political parties. GIS can build this kind of map automatically from the data
values (number of seats), and typically offers many alternative ways of presenting this information. An
example of a thematic map is a colour-coded zoning map, showing different property uses associated
with specified colours.
Identify the main differences between computer-assisted drafting (CAD) systems. automated mapping/facilities management systems (AM/FM), and geographic information systems (GIS).
• Computer-Assisted Drafting Systems (CAD): suitable for traditional mapping functions.
• Automated Mapping/Facilities Management Systems (AM/FM): provide sophisticated databases for
storing and manipulating attribute information, but are limited in their ability to analyze relationships
between different layers other than through visual inspection (overlapping of layers).
• Geographic Information Systems (GIS): developed for spatial analysis needs such as planning,
natural resources, and land records management. GIS can completely integrate spatial data and
attribute data among different layers. The GIS approach is ideal for multipurpose users.
