MultiPolygon via ArcGIS REST API

[MarkusÅfelt]

Hi,

Is it possible to use addFeatures with MultiPolygon geometry? I'm using JS API 4.10 and I'm trying to change the geometry to Polygon. Is this right way do it or is there another way? Example is appreciated.

Br,

Markus

Hi Markus Åfelt‌,

Can you please elaborate your question a little more? What are you trying to do? What does your code look like? Does it work, or do you get any error messages?

With some more information from your side, the community might be able to provide examples.

TIA,

Egge-Jan

Hi,

I am trying to use addFeatures functionality from Arcgis rest api. Multipolygon is not supported in Arcgis rest api nor Arcgis JS API so I tried to converted multipolygon to polygon using Arcgis JS API 

here is my geometry: 

return geom.coordinates.map(c => new Polygon({
rings: c,
spatialReference: { wkid: 3067 },
}));

Arcgis rest api addFeature will receive this kind of request

Something wrong with your request. "geometry" shouldn't be array. See

documentation

https://developers.arcgis.com/rest/services-reference/apply-edits-feature-service-.htm

for samples.

[MarkusÅfelt]

Yes, its because of 

return geom.coordinates.map(c => new Polygon({
rings: c,
spatialReference: { wkid: 3067 },
}));

but looks like it is impossible? to convert multipolygon to polygon? so AddFeatures would accept it... 

And still be valid data.

[Egge-Jan_Pollé · Accepted solution]

Hi Markus Åfelt‌,

Why would multipolygons not be supported by the ArcGIS REST API?

In the example below I will add a multipolygon to a Hosted Feature Layer - with some screen captures to show the result.

Is this helpful to you?

•   I add this to a Hosted Feature Layer called MY_POLYGONS

• And here they are - the highlighting shows it really is a multipolygon

[MarkusÅfelt]

Thanks for the example, I will check it out.

I just checked from data types documentation and it was missing in here?

Geometry objects—Common Data Types | ArcGIS for Developers 

or was I looking from wrong place?

[MarkusÅfelt]

Hmm, still problems... too many arrays inside of each other?

[Egge-Jan_Pollé]

Try to start with a simple example and, once you got it working, extend from there 🙂

What should your geometry look like? Any donuts with holes in it?

[MarkusÅfelt]

In this example there was 6 polygons and at least one of them had holes on it.

But I will try more simple data but I have need add more complex multipolygons... hopefully it is possible.
