Module 1: Formative AssessmentsModule 1: Google Earth Assignments You have been provided with a KMZ file containing all of the cities listed on the “Compare Cities” Page. Save this file on your computer.Open Google Earth on your computer and open the KMZ file by going to file open. The file will show on the left hand sidebar pane (make sure you have this visible by clicking on the “show sidebar” icon at top left). Click the box next to the KMZ file so it is checked. You can click on any of the city’s names and Google Earth and you will fly to that location.Begin by clicking on New Orleans, LA, U.S..New Orleans, LA, Navigate to New Orleans.Follow the directions on the New Orleans pages to guide your observations of the city.Make a point of looking specifically for structures or other types of flood mitigation (e.g., levees, flood walls and gates, pump stations, green space between water and developed land, etc.). Hint: follow the directions on the “Further Exploration” Page for exploring a portion of New Orleans’ Lake Pontchartrain levee system.Summarize your findings in the chart below:Summarize your findings in the chart below:Estimated diameter or widest point of the city:Population of city (from text provided)Complete the chart below for two locations in New Orleans that lie at, near or below sea level (The first location is given and the second you can choose). Be sure to read the background information pages for New Orleans, including the Additional Exploration” page, to give more context to your findings in google Earth.Point of interest 12Location coordinates29°58'57.33; 90°02'36.64Location elevationLocation name (if you can find one) and descriptionCharacterization of type of development (residential, industrial, port, etc.)Characterization of population density (high, medium or low density). Can you find visual evidence that the population density has changed as a result of Hurricane Katrina?Guangzhou, ChinaNavigate to Guangzhou.Follow the directions on the Guangzhou page to guide your observations of the city.Make a point of looking specifically for structures or other types of flood mitigation (e.g., levees, flood walls and gates, pump stations, green space between water and developed land, etc.)Summarize your findings in the chart below:Measure of size of city: Estimated diameter of the city (measured at 40 km eye altitude, using measure tool): just measure the width of the screen.Population of city (from text provided)3. General Observations of the cityComplete the chart below for two locations (for 1, the coordinates are given; the second you can choose) in Guangzhou that lie at, near or below sea level: Point of interest 12Location coordinates23° 02’ 30” N113° 21’ 30” ELocation elevationLocation name (if you can find one) and descriptionCharacterization of type of development: residential, industrial, port, etc.Characterization of relative population density (high, med, low)Observed flood mitigation measures (e.g., levee, flood walls and gates, pump stations, green space between water and developed land, etc.)Module 1: GeoMapApp AssignmentsNew Orleans, LAOpen GeoMap. Go to Basemap Global Grids Bathymetry Topography NASA Aster USGS Elevation Model (this is available for US only. It works best for New Orleans because it will show finer elevation changes).Click zoom (+) button; Zoom to the gulf coast of the U.S. by drawing a box around the area.Mouse over the area to find the coordinates for New Orleans (30° N 90° W). Zoom in further so the zoom level is approximately 1500 (top right corner of screen)Click the profile icon (5th from left, next to the zoom out (-) button). Create an elevation profile beginning at approximate coordinates 90.04; W; 30.01 N and extending south for 10 km. Save the elevation profile as a jpg file and paste it below. Create a second elevation profile beginning at the same coordinates and extending approximately 10 km east. Save this profile as a jpg. File and paste it below.Write a short description of the nature of elevation in the area based on the two profiles. Include the lowest and highest elevations. What would this terrain look like? How would it feel to walk or bike through the city?Based on your observations using Google Earth and GeoMapApp, what observed physical characteristics may contribute to New Orleans high rank in the flood risk lists?Guangzhou Open GeoMap. Go to Basemap Global Grids Bathymetry Topography GRMTClick zoom (+) button; Zoom to SE China by drawing a box around the area. Mouse over the area to find the coordinates for Guangzhou: N 23° 07’; E 113° 15’. Zoom in further until the zoom (shown in top right of screen) is about 1000.Click the profile icon (5th from left, next to the zoom out (-) button). Create an elevation profile beginning at these approximate coordinates and extending east for 20 km. Save the elevation profile as a jpg file and paste it below. Create a second elevation profile beginning at the same coordinates and extending approximately 20 km south. Save this profile as a jpg. File and paste it below.Write a short description of the nature of elevation in the area based on the two profiles. Include the lowest and highest elevations. What would this terrain look like on the ground – how would it feel to walk or bike through the city?Based on your observations using Google Earth and GeoMapApp, what observed physical characteristics may contribute to Guangzhou’s high rank in the flood risk lists?Comparing the two cities:Compare the nature of the elevation in Guangzhou with that of New Orleans. How do they differ?In what ways are the two cities alike (identify at least two ways)?Module 1: Summative AssessmentSummarize your findings of your analysis of the two featured coastal cities: Guangzhou, and New Orleans.Write a ConclusionAfter making observations and doing further reading, summarize your findings of your analysis of the two featured coastal cities: Guangzhou and New Orleans. Write a thoughtful reflection based on the explorations you have done using Google Earth and GeoMapApp. Incorporate thinking about the key questions below.How do the various characteristics of a city (including its economy) affect its ranking on the World Bank lists? Include thoughts on:Why is Guangzhou at the top of both lists?Why is New Orleans the only US city to appear on both top ten lists?How measures to mitigate risks (e.g., levee and flood gate improvements in New Orleans) may affect a city’s rank.Speculate on how these cities will rank in a future analysis of this kind.Add any additional thoughts based on any further exploration of the other cities in the lists. ................
