Using Arcade to classify my data

AndrewEastop — Tue, 14 Sep 2021 09:46:05 GMT

Hello everyone,

I have created a new field called 'Settlement_class'. I want it to have two options (Settlement/Non settlement) based on the data in the Band field beside.

Bands B G H are settlements and the rest are non settlements. Is Arcade the best way to go about this?

Any help would be very much appreciated

thanks

A simple python expression would be easy as well?

try replacing fld with your fieldname in ! marks below ( !FieldNameHere! )

fld = 'B' ['Non-Settlement', 'Settlement'][fld in ['B', 'G', 'H']] 'Settlement' fld = 'C' ['Non-Settlement', 'Settlement'][fld in ['B', 'G', 'H']] 'Non-Settlement'

var settlement_bands = ["B", "G", "H"] if(Includes(settlement_bands, $feature.Band)) { return "Settlement" } return "Non settlement"

You can use that expression

in the CalculateField tool (switch language to Arcade) to permanently store it in the table
in the popup, to show it only there (useful if it changes a lot)
in an Attribute Rule, to store it permanently in the table whenever a featire is created and/or updated
