Choropleth Mapping Quiz
Test your knowledge on choropleth maps and map projections with this engaging quiz! Dive into the essential concepts of spatial data representation and understand the intricacies of different map types.
Topics covered include:
- Data classification on maps
- Map projections and their properties
- Types of data suitable for choropleth maps
Why should you classify data on a chloropleth map?
So data values are obvious
So the class ranged are easy to identify
So the data is structures
None of the above
The enumeration units associated with chloropleth maps are often not related to the data because
They are collected at different time
The units are related to how we collect data, not how the data is distributed
The units are always logically structured, whereas data is not
None of the above
A value that is important to not have in a data class but between data classes is refereed to as
Inter-class value
Critical value
Classless value
None of the above
Which of the following types of data would be appropriate for chlororpleth maps?
Earth surface relief
% population with AIDS to total population
Land use
None of the above
One problem with chloropleth map is
It hides the specific data values from the user
It only uses a single color to show the data classes
It is often complicated and time consuming to create
It can not show data over large areas
All of the above
Which of the following is incorrect for a conformal projection
Scale change must be the same in all directions at a given point
Lines of latitude and longitude must cross at 90
A unit area on the map must represent the same unit area on the globe and be the sae anywhere on the map
If a map projection has a scale change in all directions at any give point it is most likely which property?
Equal area
Equidistance
Conformality
Correct direction
What is the different between orthodrome and loxodrome
An orthodrome is a compass heading and a loxodrome is a great circle
A loxodrome is a compass heading and a orthodrome is a great circle
An orthodrome is a conformal and loxodrome is equal area
None of the above
Based on the slide set- What are the three primary surfaces the globe is projected on to
Mercator, lambert, gnomonic
Orthographic, stereographic, gnomonic
Polar, equatorial, oblique
Planar, conic, cylindrical
None of the above
What projection would you suggest I use if I wanted to map russia?
Cylindrical mercator
Conic albers
Planar gnomonic
Cylindrical lamber
The projection below is a good choice to represent
The world and is conformal
The world and is a compromise
Area comparison and is equal area
None of the above
Of the projections discussed in the class which is most often recommended for representing the mid latitudes
Cylindrical
Planar
Conic
None of the above
For a projection to be equal area which of the following statements cannot be true?
Scale change in one direction must be offset by a scale change in another
A unit area on the map must represent the same unit area on the globe and be the same anywhere on the map
Angular shapes cannot be correct
Angular shapes must be correct
