Assignment 2 data - this is attached at the end of this assignment for you to download. Reference - Asefa, M., Cao, M., He, Y., Mekonnen, E., Song, X., & Yang, J. (2020). Ethiopian vegetation types, climate and topography. Plant Diversity, 42(4), 302-311. In mountainous regions, environmental change is found to strongly vary with elevation (Asefa et al., 2020). In order to study the threats to ecological health in countries in the Horn of Africa, environmental scientists need a map showing classes of elevation. 1. You are tasked to produce a map for this purpose. 2. Download and extract the data for this assignment from the folder named "2400_Lab_data". 3. Open ArcMap, and use the ArcCatalog window to connect to the folder "2400_Lab2_data". O Refer to Exercise 4a - Use Catalog Tree (Steps 1 - 4) 0 Refer to Exercise 4a - Use Connect To Folder button (Steps 5 - 8) 4. In the ArcCatalog window, explore the "Data" subfolder in "2400_Lab2_data". Identify the layers which are relevant for mapping for countries, elevation and relief. 0 Refer to Exercise 4a - Display icons on the Contents tabs (Steps 9 - 24) O Refer to Exercise 4a - Access metadata (Steps 24 - 27) 5. From the ArcCatalog window, drag the relevant layers only and add them to the map display in ArcMap. 0 Refer to Exercise 4b - Transfer data from ArcCatalog to ArcMap (Steps 1-13) 6. Order the layers appropriately so that they are all visible. 0 Refer to Exercise 3a - Ordering layers (Steps 6 - 7) Refer to Exercise 7a - Order layers (Step 11) 7. Symbolize the elevation layer. Use the default classification which ArcMap gives you. Choose 10 as the number of classes. Choose Elevation #2 for the color ramp. [2 marks] 0 Refer to Exercise 7b - Symbolize using value field (Steps 1 - 10) 8. Adjust the breaks for the lowest elevation class. Under Classify, change the Break Values for the lowest elevation class from 287 to 0. In the Symbol column, double click the lowest elevation class (-169 - 0) and choose Mars Red in the color pallete. [2 marks] 0 Refer to Exercise 8a - Classify features by standard methods (Steps 10-15) 9. Round the decimal points of the break values. Click the Label column heading and click Format Labels. Under Numeric, round the Number of decimal places to 0. Check the Show thousands separators box and Pad with zeros box. [1 mark] O 10. Refer to Exercise 8a - Format labels (Steps 16 - 21)) Change the elevation layer's transparency so that the hillshade layer is visible. Double-click the Elevation layer > Layer Properties > Display tab > Transparency text box > 70. [1 mark] Refer to Exercise 7d - Use styles (Step 15) O 11. 12. Label the countries in Africa. Change the Text Size so that it is big enough to be legible when printed but not too big to interfere with other map symbols on the map. Change the Color of the text so that it contrasts with the background colours. [1 mark] O Refer to Exercise 7b - Label features (Step 18 - 21) O Refer to Exercises 9a, b, c and d. O 0 O O 0 O O Add map elements. an appropriate title describing what the map is presenting. [2 marks] Refer to Exercise 10b - Add a title and text(Steps 1 - 25) an appropriate legend for all layers that included in the map. [2 marks] Refer to Exercise 10c - Create a legend (Steps 18 - 32) a scale. [1 mark] Refer to Exercise 10c - Add a scale bar (Steps 5 - 17) a north arrow. [1 mark] Refer to Exercise 10c - Create a north arrow (Steps 1 - 4) a text box including your name, course and lab assignment information. Include a background for this text box. [2 marks] Refer to Exercise 10b - Add ancillary text (Steps 1 - 25) a neatline. [1 mark] Refer to Exercise 10 - Add a neatline (Steps 15 – 18) an extent indicator. [2 marks] 13. 14. 15. Refer to Exercise 10 - Add a neatline (Step 21) Set the page layout and printer layout for your map. Export the map to PDF. O Refer to Exercise 10 - Specify page layout (Steps 19 - 21) Refer to Exercise 10 - Specify printer settings (Steps 22 - 24) Refer to Exercise 10 - Export map to PDF (Steps 25 - 31) Briefly explain the suitability of different classification methods for the data set used to create the map above. 0 After creating the map according to the instructions above, which type of classification method would you associate with your map? What are the merits of this method? [2 marks] 。 Go to the Symbology tab and view the histogram. Based on the histogram, is the equal interval classification method suitable for this data or not? Explain your answer in the context of the histogram. [2 marks] 0 Based on the histogram, is the natural breaks classification method suitable for this data or not? Explain your answer in the context of the histogram. [2 marks] 。 Based on the histogram, is the standard deviation classification method suitable for this data or not? Explain your answer in the context of the histogram. [2 marks] O Based on the histogram, is the geometric intervals classification method suitable for this data or not? Explain your answer in the context of the histogram. [2 marks] 。 Based on the histogram, is the quantile classification method suitable for this data or not? Explain your answer in the context of the histogram. [2 marks] O ооо This section should be one page long only. 。 Arrange your answers in the same order as the questions. Write up your answers in Word and then convert it to PDF. Merge the written part to the map created earlier. Submit a single PDF in Moodle./n NOTE: We need to find the answers and sum up in the word document. Also export the MAP to PDF. Submit a single PDF only.
