feature service

How many feature we can load to arcgis javascript 4.6 api view? how we can increase feature numbers? I have a feature service that has 120000 features. I have problem to load and view this map.

In the 4.x api you can use webgl rendering to allow for hundreds of thousands of features.

https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-FeatureLayer.html#webgl-rendering

test if if your browser supports this feature

I add this before js load(2 weeks ago), but no result!!!

I,m on 3d view and webgl is ok on my computer, but scene view can not load more than 3000 features!! :

<script>
	var dojoConfig = {
	has: {
	"esri-featurelayer-webgl": 1
	}
	}
	</script>

Hi Robert

I guess you are too busy or don't like to answer my questions. If you don't answer questions in this blog, there is not any person to answer. This mean we have to migrate

Migrate to what?...

So let me try an explain. I provided the documentaton and a sample that shows how to achieve what you asked. I personally have not need for the 3D environment and definitely have no need to display 120,000 features in a featurelayer. If I even had a need to display that many features I would always use a MapImageLayer and let the Server handle the load instead of expecting a clients browser to handle it.

There are time on GeoNet that I will not answer a question because of several reasons:

The poster has a tendency to not listen to the replies
The poster is asking for something that it is obvious they don't need but is just the latest cool thing (which in my book 3D is)
I am just busy
I don't have any experience with the area in question
A poster will not provide the code or services that they are using in order to make helping them easier.
They don't understand that people that reply are not obligated in any way to respond it is just a courtesy

Anjelina,

If you believe that there is a bug in the API then you need to contact esri tech support about it. Once again if it was me I would be using a MapImageLayer NOT a FeatureLayer to display that many features.

MapImagelayer can not use for showing buildings(polygon) and extrude as 3d. Is there any solution instead of feature layer?

Re: feature service

RobertScheitlin__GISP — Tue, 23 Jan 2018 17:48:00 GMT

In that case you need to use FeatureLayer. So calling tech support to see why you are not able to get the 120000 features is your only option.

1- Do you know why webGl and this script can not solve problem in Scene view?

<script>
	var dojoConfig = {
	has: {
	"esri-featurelayer-webgl": 1
	}
	}
	</script>

2- how we can contact arcgis java script team?

Anjelina,

1. I do not know why it is not working for you.

2. You don't contact the JS API team directly, you contact esri tech support.

Re: feature service

anjelinaponkerat — Tue, 23 Jan 2018 18:47:31 GMT

you said :"... is not working for you(Anjelina)", Does webGl work for you(Robert) to load 1200000 or more features on 3d view?

Re: feature service

RobertScheitlin__GISP — Tue, 23 Jan 2018 19:02:25 GMT

The esri sample works fine. I do not work with building data with that many records in 3D, so no I don't have it working in a setup like yours.

- The new webgl rendering referenced above is only for 2D MapViews; see webgl-rendering

- If you have a lot of 3D data, then please use Pro to publish your data as Scene Layers; that is what they're designed for.

Do you know about next arcgis java script release? Does esri add webgl-rendering for 3d Scene view?

Re: feature service

JohnGrayson — Thu, 25 Jan 2018 19:17:15 GMT

The SceneView rendering is already done via webgl. If you have a lot of data that you want to visualize in 3D your best solution is to use Scene Layers.
