Fanout typu prvku?

AdamRepsher

Ahoj znovu,

Stále pracuji na druhém školení ETL (pro starší verze Desktopu) v ArcGIS Pro. Vím, že existují rozdíly, ale toto jsou jediná školení ETL pro prostorová data, o kterých vím.

Pracuji s Pro 2.6.3 a FME 2020.0.1.0 (20200407 - Build 20218 - WIN64)

Školení: Řízení překladů dat pomocí procesů Extract, Transform a Load | Esri Training Web Course

Konečně potřebuji použít funkci "Fanout" u Writer Feature Type.

Mám dva Reader Feature Types napájející PointOnAreaOverlayer, jehož bodový výstup je připojen k Point Shapefile Writer Feature Type. Prvním problémem bylo zjistit, jak duplikovat magické propojení ze školení mezi všemi akumulovanými atributy uvedenými v PointOnAreaOverlayer a Writerem. Postupoval jsem podle pokynů, ale po použití "Copy Attributes from Transformer" měl atribut "Name" ve Writeru červený uzel a při spuštění nedostal data z Overlayeru. ("NAME" je pole v polygonové vrstvě, které musí být zachyceno ve výstupu bodu.) Našel jsem Attribute Accumulation - Merge Attributes v Overlayeru a nastavil Accumulation Mode na "Merge Incoming". To umožnilo Overlayeru zobrazit polygonový atribut "NAME" v seznamu atributů bodového výstupu a být viditelný pro point Writer. V předchozích verzích FME to nebylo nutné? Nebo více funkcionality vyžadovalo další vrstvy konfigurace?

Nyní k opravdové části otázky...

Potřebuji provést "Feature type fanout." Zde je obrázek ze školení jednoduchého zaškrtávacího políčka a výběru kategorie v rámci vlastností Writer Feature Type:

Zde jsou vlastnosti Writer Feature Type, které vidím v Pro/FME:

Kde je funkce Feature type Fanout?

Díky,

- Adam

Adam for the first part of your question, attribute names are case sensitive so you'll need to create an attribute connection from NAME in your data to Name on the writer. This is easy manually but if you had dozens to do there is also an automated way.

You have found the feature type fanout, it is 'Fanout by Attribute' in the old UI. Here is a good topic for the current experience:

Thank you @BruceHarold . I intend to keep using Pro since it is the way forward! Just bear with all of my questions....

bharold

Adam you found the recommended way to get the area feature attributes onto the points, maybe the merge behavior default changed between releases. Please keep using Pro anyway.

Okay - I think I got the 2nd part - just use an attribute value in the Shapefile Name parameter. THANK YOU @BruceHarold !!! That makes it incredibly easy. 👍

Back to the first part of the problem. I am aware of the case sensitivity, but didn't document that well in my question. The correct case in the field (all caps) is carried over from the Readers to the Transformer and also to the Writer when connecting them. Here is my view after following the steps in the training to connect everything (Yes, this is still me working in Pro - not as the training is done in Desktop v10.5):

My connections before "Copy Attributes from Transformer"

This is what the training says to do next:

Instructions from Training

...and their example of what it is to look like when done:

Training after instruction

BUT - The following is what I get after I complete the step of "Copy Attributes from Transformer":

My Result

So, I get the attribute carried over from the Area section of the Transformer to the writer. I think I am seeing the lack of connection of the NAME attribute because the desired action of the "Overlayer" (actually incorporating the Area's NAME into the point data) is not happening automatically, as it must have done in previous versions of Desktop/FML?

I then did a bit of hunting for an answer. Tell me if I found the right/best method to accomplish what I'm trying to do...

Found in the PointOnAreaOverlayer Parameters - the "Attribute Accumulation" section and "Merge Attributes" which I set:

Although I do not need the Point attributes added to the Area data - I DO now have the Area data's "NAME" attribute in the Point data - AND I am able to make the connection to the "NAME" attribute in the writer:

...and then make the connections...

I'm wondering if:

This is the best/most efficient way to accomplish this?
If the older versions of software just assumed that you wanted this to happen, and made it work that way automatically? (Because the Overlay tool in Modeler did do that.)
