Custom GL layer for a Feature Layer

This modified sample is from the Custom WebGL layer (https://developers.arcgis.com/javascript/latest/sample-code/custom-gl-visuals/index.html#).

Demo

• https://jsbin.com/saligezubo/1/edit?html,output

To make this work for a feature layer, I did the following....

• Created a feature layer class

# Sample of how to copy a feature layer from a local ArcGIS server and publish it to AGOL.
import arcgis
from arcgis import features
from arcgis import GIS
from arcgis.gis import Item
import json

gis = GIS(username="username", password= "password")

#Turn Feature Layer to a Feature Set

nommuna2

import arcgis
from arcgis.gis import GIS

# Provide credentials to the GIS object.
gis = GIS(username="username", password= "password")

#Get the id of the hosted feature layer
item = gis.content.get("id of feature layer")

#Get the feature layer itself

require(["esri/map",
         "esri/layers/ArcGISDynamicMapServiceLayer",
         "esri/tasks/query",
         "esri/tasks/QueryTask",
         "esri/dijit/Popup",
         "dojo/dom-construct",
         "esri/dijit/PopupTemplate",
    "dojo/domReady!"
], function (Map, ArcGISDynamicMapServiceLayer,Query, QueryTask, Popup, domCon, PopupTemplate) {

require([
    "esri/Map",
    "esri/views/MapView",
    "esri/layers/FeatureLayer",
    "dojo/domReady!"
  ],
  function (Map, MapView, FeatureLayer) {

    const filter = document.getElementById('state');
    //Create a new map and set the basemap to Dark gray

Add Shapefile from disk to a map in 4.x

This sample is a modified 4.x version from the 3.x version linked here (https://developers.arcgis.com/javascript/3/jssamples/portal_addshapefile.html).

nommuna2

#Adding an item to AGOL and publishing it
csv = r'path to csv' 
csvItem = gis.content.add({}, csv)
csvFeatureLayer = csvItem.publish()


#Overwriting a service
#Search for the FeatureService by name 
MyFeatureService = gis.content.search(query='title:SampleTest AND owner:owner')
#Get the id related to the Feature Service

nommuna2

// This sample uses the server to find if any points are within a certain polygon. 
// This option only uses one for loop to go through each polygon and then uses a spatial filter as input to the query for the points.
// For this option your points would need to be on the server either through a map service or a feature layer.

#Using a feature layer
import arcgis
from arcgis.gis import GIS
from arcgis.features import FeatureLayer

gis = GIS()

# Use the FeatureLayer class to get item from an service endpoint
url = 'https://idpgis.ncep.noaa.gov/arcgis/rest/services/NWS_Climate_Outlooks/cpc_6_10_day_outlk/MapServer'
layer = FeatureLayer(url)

import arcgis
from arcgis.gis import GIS
import requests


gis = GIS(None,'username', 'password', verify_cert=False)
try:
    featureLayerItem = gis.content.get('item id')
    r = requests.post('https://{0}/sharing/rest/content/items/{1}/setContentStatus'.format('org domain',featureLayerItem.id), data= {'status': 'org_authoritative','clearEmptyFields': 'false', 'f':'json', 'token': 'token'})
    print(r)
