Produce choropleth maps integrating social vulnerability and risk

[ptormene]

We need some kind of custom operator that:

• takes the range of the scocial vulnerability and divides it into 3 intervals
• does the same for risk
• assigns to each feature a letter (A, B or C) for the social part
• assigns to each feature a number (1, 2, or 3) for the risk part
• concatenates letter and number to produce something like B2 for the feature
• produce a categorized style classification using those 9 classes
• the color of each category should be taken from a pre-determined palette

This is an example of what Miguel and Michael used to calculate the categories:

Ecoomic vulnerability "SV_ECO"

CASE WHEN "ECONOMIC_R" > 0.31822 THEN 3
WHEN "ECONOMIC_R" <= 0.31822 AND "ECONOMIC_R" > 0.22469 THEN 2
ELSE 1
END


Economic Losses "PR_ECO"

CASE WHEN "SUM_STRUCT" > 8091446.55 THEN 'C'
WHEN "SUM_STRUCT" <= 8091446.55 and "SUM_STRUCT" > 1824223.6 THEN 'B'
ELSE 'A'
END

INTEGRATION "IR_ECO"

concat("PR_ECO",tostring("SV_ECO"))
