October 21st – Lab 3

Answer from Question 5: What percentage of the city of Vancouver’s total area is under danger. Explain the method used to determine this percentage.

  • Right click Vancouver_Danger layer
  • Select Attribute Table
  • Right click Shape_Area
  • Select Statistics
  • Here, you can see the Sum of all of the shape areas (15889260.283541m2)
  • Next, right click on Vancouvermask and then Attribute Table
  • Here, you can get the total shape area under the Shape_Area column (131033339.950334m2)
  • To find the percentage, divide the sum of all of the shape areas in the Vancouver_Danger layer by the total shape of the Vancouvermask layer
  • 283541m2 / 131033339.950334m2 x 100 = 12.126120184%

Therefore, the percentage of the City of Vancouver’s total area in danger is 12.126120184%.

Answer to Question 6: List the healthcare and educational facilities within the Vancouver danger zone, if any explain how you came up with your answer.

  • Go to ArcMap toolbar and select Selection
  • Click Select by Location
  • Selection method should be ‘select feature from’
  • Target layer(s) are Vancouver_health and Vancouver_education
  • Source layer is Vancouver_Danger
  • Spatial selection method for target layer feature(s) is ‘interest the course layer feature’
  • Click Okay
  • Right Click on the Vancouver_health layer, then select Data and then Export Data
  • Ensure that you are only exporting ‘Selected features’ and using the same coordinate system as ‘this layer’s source data’
  • Rename the Output feature class health_danger since these are the two layers that are being intersected
  • Repeat for the Vancouver_education layer

Accomplishment Statements for each lab:

Lab 1: Studied the basic concepts of ArcGis in order to begin my understanding of the program to best use it in the future in GEOB 270 and future endeavors.

Lab 2: Explored the uses of vector and raster data in ArcGIS in order to produce a map that properly visualizes both to an observer of the map.

Lab 3: Benefited from the use of completing spatial and tabular datasets to manufacture a map that displayed areas of Vancouver that would be at risk if a tsunami were to occur.mylab3 Nicole Rich
