IMPORTANT: Carefully read through the Unit Assignment instructions and watch any accompanying videos. Assignment videos provide information and guidance about completing the assignment, but DO NOT provide exact step-by-step instructions on what is to be done. Students are given the opportunity to experiment and troubleshoot how to complete the assignment.
Please note: This week’s assignment builds upon the skills you learned from the previous week and will require at least 5 hours to complete. Start working on your assignment early in the week to give yourself enough time. Last minute completion of the assignment will likely result to confusion, frustration, low quality work, and earn you a low score. DO NOT DELAY.
Learning Objectives
In this assignment, students will learn how to use selection operations in QGIS to create a series of choropleth maps that highlight certain thematic characteristics using polygons and points.
Once you have successfully completed this assignment, you would have learned:
How to select features in a spatial dataset in a variety of ways including manually, selection by attributes, and selection by location;
How to apply visual styles to spatial data in QGIS;
How to generate an aesthetically appealing and visually concise map using QGIS
Screencasts
Unit assignment screencasts provide information and guidance about completing the assignment, but DO NOT provide exact step-by-step instructions on what is to be done to complete your assignment. This is intentional so student can learn to take initiative in exploring, troubleshooting and figuring out how to complete the assignment requirements.
Review the content below. Taking notes while watching the screencast(s) to help you reinforce your understanding of the concepts and skills. Screencasts are 0n-demand and can be paused, re-started and viewed multiple times and can be viewed on multiple devices (e.g., smartphones, laptops, tablets).

NOTE: If you need to review previous screencasts to reinforce your knowledge of using QGIS, you may visit the respective week folders or unit assignment instructions in previous weeks. Please note: The following screencasts were featured in the previous week.
Deliverables
For this assignment, you will create three (3) maps in accordance with the parameters specified below:
Map #1: Create an aesthetically pleasing map of the Lower 48 states of the United States showing all cities using Graduated Point Circle symbology based on population rank. Note: You will use the shapefile data priovided (no need to google other country shapefiles.) Your map needs to have textual labels of the cities with population ranks 1-3 ONLY. For this map, use the EPSG 102009 projection (North America Lambert Conformal Conic).
Map # 2:  Create an aesthetically pleasing map of Ukraine showing all cities using Graduated Point Circle symbology based on population rank. Note: You will use the shapefile data priovided. Your map needs to have textual labels of ALL cities. For this map, use EPSG 28466 projection.
Map # 3: Create an aesthetically pleasing map of one (1) country of your choice (other than the US and Ukraine) anywhere in the world showing all cities using Graduated Point Circle symbology based on population rank. Note: You will use the shapefile data priovided (no need to google other country shapefiles.) Your map needs to have textual labels of the cities with population ranks 1-3 ONLY. For this map, use WGS84 projection.
Steps and Procedures
1. Download the shapefile data from this page (see above for zip files) and extract the shapefile folders from the zip file.
2. Review the requirements again (see above) for each one of the three maps you are required to produce.
3. Watch the associated screencasts (see above) and follow along to learn how to use the selection tool and the data classification method in QGIS.
4. For each of the maps, complete the following steps:
a) Create a new project in QGIS. Load or add the shapefiles such that the cities are the top layer and the other shapefiles are the base layer;
b) Work on your US map first. Follow along the screencasts (see above) to complete all steps necessary to create your map.
c) Display the relative population levels of cities using graduated symbols:
Classify the population level attribute (POP_RANK) under the cities layer using seven (7) “Graduated” categories.
Change the symbol size of each category so that larger populations are represented by larger symbols. NOTE: Population Rank 1 refers to higher population values. Since Population Rank 1 has a higher value, the symbol must be the largest. Pay attention to this detail to create a correct proportional symbology in your map.
You should use the same color for all classes, but the point symbols should vary in size (biggest circle must represent population rank 1, and so on).
d) Customize the style of all layers in accordance with the instructions for the specific map you are creating. Review the instructions. Your maps must only show the textual labels of the cities with population ranks 1-3 ONLY.
5) Create a Print Composer within QGIS. Make sure your map is scaled/zoomed in on your selected study area per map such that the entire map is visible and occupies most of the composer view.
a) Add essential and required map elements (e.g., name, title, neat line, legend, text boxes, source, etc.).
b) Make sure to edit your legend items and take out items that are not reflected on the map.
6) Export your map as a JPEG.
7) Repeat these steps to create your Map # 2 (Ukraine). NOTE: Your map needs to have textual labels of ALL cities of Ukraine.
8) Repeat these steps to create your Map # 3 (country of your choic other than the US and Ukraine). NOTE: Your map needs to have textual labels of cities with population ranks of 1-3 ONLY.
9) Prepare your Word document.
10) Embed the JPEG image in your text document (Word document).When adding the maps in your Word document, make sure to make the maps big (fill up the entire page) and the image is not distorted.
11) In your Word document, write a paragraph using at least 250 words to:
a) Describe all of your three (3) maps and how you created these maps, and
b) Identify at least two (2) other types of maps that you can think of where you can use the Graduated Circle Point symbology and for what purposes.
12) In your Word document, include your name, employee ID #, course name, professor’s name, date completed, data source, and provide a title for your document.
13) Export your document as a PDF, and name the file as LASTNAME_FIRST-INITIAL_UNIT4.PDF
14) Upload your PDF using the Turnitin link (see below).
