Ajouter une liste Sharepoint avec une géométrie au format Esri JSON

RaajRaaj

Dans la version ArcGIS for Sharepoint 2022.2, les utilisateurs pourront également ajouter des listes Sharepoint ou des bibliothèques de documents contenant une géométrie au format Esri JSON.
Qu'est-ce que le format Esri JSON ?<\/STRONG>
Esri-JSON encode à la fois la géométrie et les informations sur les entités dans des objets. Les types de géométrie valides sont les points, polylignes, polygones, enveloppes et multi-points.
Comment obtenir les données au format Esri JSON ?<\/STRONG>
Supposons que j'ai une couche d'entités ArcGIS Online et que je souhaite exporter les données dans une liste Sharepoint.
Je peux configurer un flux dans Power Automate en utilisant le connecteur "Get data from feature layer" d'Esri et exporter les données vers une liste Sharepoint.
Pour l'exemple ci-dessous, je vais créer une liste vide dans Sharepoint avec deux colonnes, la colonne "Office Name" qui sera remplie avec le "Office Name" et une deuxième colonne "Shape" (type de colonne : Plusieurs lignes de texte) qui sera remplie avec la géométrie au format Esri JSON.<\/P>Note : Lors de la création d'une colonne dans une liste Sharepoint pour contenir la géométrie au format Esri JSON, veuillez utiliser "Plusieurs lignes de texte" comme type de colonne.<\/P><\/TD><\/TR><\/TBODY><\/TABLE>
Lors de l'utilisation du connecteur ArcGIS "Get data from feature layer" dans Power Automate, je peux choisir des couches d'entités stockées dans mon organisation ArcGIS Online pour extraire la géométrie au format Esri JSON (choisir le format de sortie "JSON") et sélectionner "Oui" pour le paramètre "Return Geometry". Pour la couche d'entités utilisée dans l'exemple ci-dessous, je peux voir que la géométrie a été stockée au format Esri JSON à partir des métadonnées de la couche. Je peux maintenant extraire le champ shape et l'exporter vers une liste Sharepoint qui pourra ensuite être ajoutée au composant web map sur une page Sharepoint.
L'enregistrement d'écran ci-dessous montre étape par étape comment configurer le flux Power Automate et exporter la géométrie au format Esri JSON vers une liste Sharepoint.<\/P> <\/P>https:\/\/players.brightcove.net\/6161463677001\/default_default\/index.html?videoId=6310610323112

Hello, Thanks for the video and pointers.

I tried out this flow, it appears to work, pulls all the attributes from my feature in AGOL into the list. Including what looks like a JSON for the Shape.

but I get an error in sharepoint "The selected column doesn't contain any valid JSON geometry"

Any idea why?

my Shape column has this as an example:

{"rings":[[[1634982.61335695,7380760.53151438],[1634976.8421821,7380761.35197642],[1635015.95253566,7380985.71551994],[1635021.69189794,7380984.71076092],[1634982.61335695,7380760.53151438]]],"spatialReference":{"wkid":102100,"latestWkid":3857}}

Thanks in advance for any help

@AndrewWalker3 - Thanks for your feedback.

Regarding your question, can you check the column type and make sure that you've selected "multiple lines of text"? By default, SharePoint assigns "Single line of text" which has a character limit and it truncates the JSON. Once you change it to "Multiple lines of text", it should work.

Let me know if you have any further questions.

Raaj

AndrewWalker3

Thanks. But actually it is multiple lines. So I don't understand why I have the error.

Anything else to check for?

RaajRaaj

Can you send me the name of the layer? Let me try add it on my end.

AndrewWalker3

Hey RaajRaaj,

i DM you with the name of the layer. Did you get a chance to look?

I have another question on ArcGIS for sharepoint. When you search documents it searches across all sites. is there a way to force it to search in the current site only and remove the options for a user to search across sites.

If we have organised our data into projects in sites we would NOT want users for that site being able to search other sites.

RaajRaaj

Hi Andrew,

I just checked my inbox this AM and I've responded to your message.

Regarding the "search" functionality, am assuming you are asking about the "geosearch" functionality in ArcGIS for SharePoint? If yes, then its possible, but I would like to get some additional details.

If you'd like the page "viewers" to only be able to geosearch documents within the current site, then the author of the page can check the box next to "Search within current site". Once that box is checked by the map author, the setting gets saved.

But with the above option, viewers will be able to change the "Search" options and uncheck the box.

If you dont want to let the viewers to uncheck the box, then the other option is to let the author of the SharePoint page to check that box and once that box is checked, viewers will not be able to uncheck it. If you think this is a viable solution, then we need to address this in a future release and I would need to talk to my team and get back to you on when we can push this to Production.

Let me know your thoughts?

Raaj

AndrewWalker3

Thanks Raaj,

Yes i had been using the search site only button. But I don't want users to be able to uncheck this.

It would be good if I checked this inside "edit mode" then it could be fixed and greyed out for users. The issue for us is that with this unchecked users can actually search documents on other sites (they should not be able to see) if they happen to have similar enterprise keywords or terms associated.

RaajRaaj

Got it! I will work with my team and will let you know on when we will be able to push this to Production.

Thanks,

Raaj

AndrewWalker3

Also Raaj. I made the layer public for you to check on the power flow.

Andy

RaajRaaj

@AndrewWalker3 - I tried adding the layer and when I look at the layer's metadata, I don't see the Shape field exposed which I need to use in the Power Automate flow to extract the JSON.

AndrewWalker3

@RaajRaaj

I used "geometry" in my flow

flow esri.PNG

and i get the data into my sharepoint list like this:

RaajRaaj

@AndrewWalker3 - Thanks for the screenshot. I was able to use the "geometry" column and extract the JSON into a Sharepoint list and then I was able to add the SP list to a map without any issues.

AndrewWalker3

ok,

i tried from scratch again with a new list with just the title and shape and it worked.

It might have been due to it already being an existing list which I copied from an excel. Might have had an issue with the column not being formatted to multiline like you said originally. (even though I did check it)

Thanks for the support

Andy

RaajRaaj

You're welcome! 🙂

Hi there,

Thanks for providing this overview! Is there any chance of providing the video in a less pixelated format? It's quite difficult to see what you are actually demonstrating in it.

Alternatively, can you link to written documentation for accessing the geometry of a feature layer with this method? Your post seems to be the only thing on the internet with any information or guidance on what an esriJSON is or how one can use it, irrespective of whether it's being used within Sharepoint or not.

RaajRaaj

@dcallaghan -

Here's the link that explains how to convert features to Esri JSON.

https://pro.arcgis.com/en/pro-app/latest/tool-reference/conversion/features-to-json.htm

Let me know if this helps?

Also, I will send you the videos within an hour or two.

Thanks,

Raaj

RaajRaaj

@dcallaghan - Here's a high resolution video. Let me know if you have any questions.

Thanks,

Raaj

Hello,

I'm trying to reproduce the format listed here in arcgis for excel without any success. Actually, it seems incredibly glitchy.....Can you update this post to include more information about data prep to have ESRI JSON objects work? I couldn't find anything.

RaajRaaj

@Stefan_Bazar123 - This flow that I've explained in the blog is meant for Sharepoint lists. Do you want the steps to set up a similar flow that can work with Excel?

Thanks,

Raaj

Stefan_Bazar123

yes I think that would be very helpful. Or just more information on how to format ESRI JSON

RaajRaaj

@Stefan_Bazar123 - Could you please share the workflow steps and the step where you are encountering the formatting issues so that I can better assist (with some screenshots, if possible)?

Thanks,

Raaj
