FeatureSet Not Returning the Correct Value

ChelseaTabor — Tue, 18 Oct 2022 13:50:28 GMT

I'm attempting to create a featureset in ops dashboards to return the number of points contained within a polygon, however I'm getting the same number of points for each polygon. Am I missing something in my data expression? I'm in Enterprise 10.9.1.

var portal = Portal('myportal')

var poly_fs = FeatureSetByPortalItem(portal, 'c879aa9267604224a3f6d492fc997a50', 7,['ZONE_NAME'],true)

var pt_fs = FeatureSetByPortalItem(portal, '44fa0f9330e449c289dfadf2553d805b', 0,['leaktype','leakloss',],true)

var features = []
var feat

for (var poly in poly_fs){
var pts = Contains(poly, pt_fs)
feat = {attributes:{
mmz: zone['ZONE_NAME'],
number_of_leaks: Count(leaks)
}
}
Push(features,feat)
}

var dict = {
fields:[
{name:"mmz",alias:"Zone",type:"esriFieldTypeString"},
{name:"number_of_leaks",alias:"Number of Leaks",type:"esriFieldTypeInteger"}
],
geometryType:"",
features:features
}

return FeatureSet(Text(dict))

Where is the variable "leaks" coming from in this section?

for (var poly in poly_fs){ var pts = Contains(poly, pt_fs) feat = {attributes: { mmz: zone['ZONE_NAME'], number_of_leaks: Count(leaks) } } Push(features,feat) }

Sorry, that should say 'pt_fs'. I changed variable names for this post.

In that case, you want to get the count of how many point were in the polygon, so it should be

number_of_leaks: Count(pts)

That worked. Thanks!
