LDARCH/ESPM C110 Ecological Analysis Fall 2023 Lab 2 Questions for Lab Report Question 1: After you have saved your project to the appropriate location, take a screenshot of your dedicated folder for LA110 ArcMap data that shows the contents of the folder for Lab 02/Week 02 and paste in your Lab 2 report. Write out the full file path and include in your report as well. Question 2: Examine the layers and write the answers for the following: a) What type of data file is ucamp2004.tif. b) What type of data file is uc_contours_2ft? c) What units are each layer in? d) What projection do these files use? e) What is the spatial resolution of uccamp2004 raster? Question 3: Why are contour lines located closer to each other in the northeastern corner of the map screen? If you were standing somewhere in that region of the map, what direction do you think you would be more comfortable walking in - East or West? And why? Question 4: Based on your understanding of the process of interpolation described above (in the instructions), what potential problems and limitations can you imagine that terrain visualizations based on interpolation from contour lines have? In other words, how do you think a DEM created through interpolation compares to the actuality of the terrain it represents, and are there potential pitfalls, problems, or limitations to what an interpolated surface can represent? (2-4 sentences) Question 5 : Using the Identify button, the procedure described in the previous step, and the reference map below, write down in your lab report the slope values in percent and degrees for the following campus locations: Location Slope (percent rise) Slope (degrees) % Slope from field Faculty Glade 30% Annual Grassland Ecosystem 41% Centennial Drive 13% Question 6: Compare these GIS-based results with slope values estimated in the field (the right column). What reasons may explain the difference in magnitude of the slope steepness between field data and values in the table derived from spatial data in ArcGIS? (Hint: think about how we derived digital slope data in this exercise and spatial resolution of the raster layers for DEM and slope). Question 7: Do you see a relationship between the degree of slope and the orientation of the slope? Explain your reasoning. (2-3 sentences) 1

LDARCH/ESPM C110 Ecological Analysis Fall 2023 Lab 2 Questions for Lab Report Question 8: Discuss the following questions in no more than 8-10 sentences: What do you intend to show with the map that you created? Why did you include the layers that you included and excluded others? Why did you use the particular colors you did? Transparencies? Please include any other relevant points. Question 9: Take a screenshot of your map display showing your study area, profile line and the profile graph and paste into your Lab 2 report. Think about the information represented in this profile. Question 10: a) Take a screenshot of your profile graph from Excel and paste into lab report. b) Describe in 3-5 sentences what information this profile is conveying. How does elevation change along this path? c) Without computing the slope, discuss how the steepness and your ease of walking would change along this route. Question 11: a) Include a screenshot of your multi-sectional path on top of either DEM or campus image together with the graphic profile plot generated by ArcMap; b) Include an Excel graph of this same multi-sectional plot formatted and customized after exporting. c) Discuss briefly (5-6 sentences) the advantages and limitations of this topographic profile approach for assessing elevation changes along the path for someone who may be interested in elevation changes along a hiking or driving route. What information can be provided relatively well by a profile graph generated in Excel or ArcMap? What information is missing or cannot be adequately conveyed without additional steps (hint: what about your multi-section profile cannot be learned from the Excel chart?)? Feel free to include any additional points. Question 12: Find a map that shows topography as an important element of the map . In a bulleted list include the following information: - An image of the map itself. - Designer/Author , if known - Title of the map, if known - Date or era of creation, if known - Source or platform you found it in (i.e. if it’s in a book, on DavidRumsey, etc.) - The intended use of the map or a description of your interpretation of the map’s purpose. (1-3 sentences) - Whether or not it has all of the classical cartographic elements (scale, legend, directional marker and title) - How does the inclusion or exclusion of those classical cartographic elements affect how legible the map is or how the map can be used? (1-3 sentences) 2

LDARCH/ESPM C110 Ecological Analysis Fall 2023 Lab 2 Questions for Lab Report - Specifics about the aspects of the map that appeal to you and why they appeal to you. (1- 3 sentences) - Provide a few critical comments about whether any aspects of this map could be improved further to enhance its informative value or usability, particularly with respect to topographic properties and feel free to include suggestions what specific change(s) might be recommended. 3
