Hello, I wished to summarize the length each route type based on the Map_NO. For example, in Map_No 000, it will give me the length of the total of Program #1, Program #2 and Islands & Turning Lanes. My reader is a line feature class, and I also have separate Map Index class. Ideally, I would like to have attributes about distance of each route type for the associated Map No. I have tried the Sampler, StatiscticsCalculator, Aggregator etc and they didn't give the result I wanted. Maybe there is anything setting or other transformers I could try? Thank you.

First use the LengthCalculator to store the length in an attribute LENGTH.

Then use the StatisticsCalculator (group by MAP_NO) attribute to use LENGTH and the SUM output will get you the result.

Hope this helps.

It does give me a lump sum of all the line segments within each Map_No, but it didn't break the value into different line types.

Hi @koala18,

Please add ROUTE_TYPE to the Group_By.
