+12Hello, I have a table with 3 records per house. The table includes hundreds of houses. I want to create a new attribute called Type. There are two types only : A and B.
For Type A: two values of attribute a1 per house equal the value of attribute a2 of another record of the same house.
For Type B: two values of attribute a2 per house equal the value of attribute a1 of another record of the same house.
How can I automatically assign the type to each record of any given house? Thx.
+32Hi
Could you count the number of times a record occurs per house in a1 and a2 then if a1_count = 2 then Type A and if a2_count = 2 then Type B?
+48You give a nice example, because just counting the number of times a record occurs per house in a1 and a2 does not work. House x has 2 occurences of 12 in a1, and 2 occurences of 10 in a2. But the value 10 is not present in a1.
Calculate the Histogram in a StatisticsCalculator, then determine the Type. See the attached example (FME 2024.1).
Count the number of features having the same value in a1 and a2 for each House, then determine Type of House according to the criteria:
If count of a1 = 2 AND count of a2 = 1 Then A
Else if count of a1 = 1 AND count of a2 = 2 Then B
