Geob 270 – Lab 3

Posted by in Uncategorized

Lab 3: In this lab, I was immersed in a scenario where I was hired by the City of Vancouver GIS department and I was tasked with preparing a map that highlights the areas in the city that are more at risk from a tsunami. This lab worked with spatial analysis, tables, and editing.

  • During this lab, we analyzed the Tsunami risk for the Greater Vancouver area. Using the data provided, I constructed a map that differentiated the land area in danger from the area out of danger. In ArcCatalog, I selected the Sum_Shape_Area tab for the Sum Output of Vancouver_LanduseDanger and right-clicked, then selected Statistics. I recorded the “Sum” value, then I opened the Attribute Table for the Vancouvermask layer. Using the proportion for the Shape_Area of Vancouvermask to the Sum of Vancouver_LanduseDanger to attain the percentage affected, which is 15.5%.

  • Continuing on in an analysis of this map, I was able to determine that there were certain institutions that were in the tsunami danger zone.

    There are five health care facilities in the City of Vancouver’s danger zone:

  1. False Creek Residence
  2. Villa Cathay Care Home
  3. Coast west Community Home
  4. Broadway Pentecostal Lodge
  5. Yaletown House Society

And there are ten educational facilities in the danger zone:

  1. Emily Carr Institute of Art and Design
  2. Institute of Indigenous Governments
  3. Henry Hudson Elementary
  4. False Creek Elementary
  5. St. Francis Xavier
  6. Vancouver Montessori School
  7. St. John’s International
  8. Heritage 3R’s School
  9. St. Anthony of Padua
  10. École Rose des Vents

These results were attained by using the Select by Location function under the Selection tab.
