Assignment 3 | Cartographic Principals [Add your name here] Objective: In this assignment, you will implement the following: Use vector data model to create maps Experiment multiple map projections to select the most suitable map projection Work with classification and number of classes to group data into different classes Create technically correct maps (use classifications, number of classes, map projections, correct map types, colors, symbols and visual elements) with visual hierarchy Analyze and describe the algorithm (methodology) Formal writing using essays and cite sources Technical writing (answering technical questions) Potential benefits of using maps for analyzing patterns and use it for decision making S ubmit a single word document with the map and the answers to all the questions. Q1: Classification and Map Projection [42 Points] Data to use for this question: WorldGDP_2020.shp Data Source: IMF (International Monitory Fund) GDP Data 2020. For this assignment, you will need to explain the steps you took from beginning until the end to create the map. Make sure to keep screen captures of each step and write down what steps you took. This process is similar to what you see in the lab activity videos. The goal is for you to be able to explain the process to someone so that they can replicate your work using the steps you provided. Q1.1: Create a Map [8 Pts] 1. [1 pts] Using the WorldGDP_2020.shp, create a map to show the GDP (imfGDP) by countries. 2. [2 pts] Change classification to manual breaks, set the number of classes to 6. Change the classification upper limits manually to something more meaningful. 3. [1 pt] Add the grid lines. 4. [2 pts] Identify a suitable map projection by experimenting different map projections for the variable you are mapping. Make a note of all the projections you have tried. Finalize on the map projection you feel is best for this variable. Change the map projection accordingly. Make a note of the map project you used. 5. [2 pts] Complete the map by adding all the map elements. Relabel the variable names and shapefile names to something meaningful. Source is specified above. Q1.2 : Technical Questions: 1. [3 pt] Which map projections did you try? Which map projection did you finally use? 2. [1 pt] What feature is it this map projection preserving? (Hint: See link in the lab activity instructions) 3. [1 pt] Why did you select this map projection? ______________________________________________________________________________ © Nandhini Gulasingam 1
4. [12 pts] Explain the methodology - Explain step-by-step on how you created this map from downloading and extracting the shapefiles to completing your final map (For example, the first step is to unzip the compressed shapefiles and save it into a folder, and add the shapefiles to ArcGIS application) . Include screen captures while explain the steps. When you include the screen capture, cut-out only the part you are taking about so that your file size stayes small without crashing your computer. For each step, include a line indicating the purpose of the step (For example, extracting the shapefile was to uncompress the spatial data so that the GIS application can read and display the file). Q1.3: Non-Technical Writing What can you interpret from the map? Use the following questions to formulate your answer. The answer should be in an essay/paragraph format (See sample document provided on D2L) . Cite at least 2 sources. Use the correct citation method. Please note that just listing the references will result in zero points. The reference should be included in the narrative to explain the relevance of the citation. See D2L for citation instructions. Write a 1-page essay (single spaced, 11 or 12 point font). Answer to each of the following questions will be a separate paragraph. To earn the full score, it has to be in an essay format with multiple paragraphs answering each question in a separate paragraph. 1. [1 pt] What is the purpose of the map? 2. [2 pts] Define and explain the term GDP. Use a reputable source to find the definition. 3. [2 pts] In your opinion what is considered a high GDP and what is considered a low GDP value? Explain. 4. [3 pts] Which countries have high GDP and what are the reasons for this? Explain why? 5. [3 pts] Which countries have low GDP and what are the reasons for that? Explain? 6. [2 pts] Do you see any outliers or anomalies? Also, are you surprised by any of the country’s GDP values? Explain. 7. [4 pts] Explain which 2 industries can benefit from this map and how? i.e. Explain in detail as to how they can use it. Rubric: Meet expectation In progress of reaching the benchmark Needs improvement 1. Comply with guidelines 100% of the points : the report/map are written/made clearly and complies with the guidelines. 80% of the points: the report/map are not written/made clearly while following the guidelines over 80% OR the report/map are written/made clearly following the guidelines only 60-90%. 50% or less of the points: the report/map follows the guidelines less than 50% regardless of clarity. 2. Use computational thinking (CT) * concepts and skills 100% of the points : clear demonstration that you correctly used CRS as CT concepts and skills. 70% of the points: vague demonstration that you used CRS correctly as CT concepts and skills. 25% of the points: you incorrectly used CRS as CT concepts and skills ______________________________________________________________________________ © Nandhini Gulasingam 2
