QUESTION 2

The recent flooding in BC shows that this natural hazard can have extensive impacts, disrupting

human lives and wiping out economic livelihoods. You are asked to creat a map showing

locations in the City of Abbotsford where current human populations are at risk of flooding.

How would you create such a map that shows these locations at risk to flooding? While you

would not be working in ArcGIS Online, it is a good idea to think through how you do such an

analysis in a software environment to structure your thinking below.

Name and briefly describe the key attributes of 3 data layers for the analysis and justify each layer selection

Draw a flowchart diagram (boxes and arrows with labels) showing your process starting from input data to GIS analysis and ending at the risk map. Use the drawing tools in MS-Word or draw on paper then photograph the image and insert here. But whatever you draw must be created by you and not taken or copied or modified from the internet or elsewhere.
