Question

10. the impact of flooding on austin would depend on the flood frequency and the density of the population. use the tracts and soils feature classes to calculate a flood impact index based on the population density times the flood frequency (afldfreq). capture a choropleth map showing the index (include the contents pane with symbology). what aspect of the input data most limits the applicability of this map?

Answer 1

To calculate the flood impact index, multiply the population density by the flood frequency. Create a choropleth map to visualize the index.

• To calculate the flood impact index, you will multiply the population density by the flood frequency (afldfreq).
• First, you need to obtain the population density and flood frequency data.
• Then, multiply the two values for each tract or soil region to get the flood impact index.
• Finally, create a choropleth map that visually represents the index, using different colors or shades to indicate varying levels of impact.
