Arcade Expression to summarize values in text string

AustinCanty1

I have an arcade expression for a popup that returns a text string comprised of a land use description and a length. How would I go about summarizing the total length by the land use description? 

 

var buffer = BufferGeodetic($feature, 50, "feet")

var int_ma = Intersects(FeatureSetByName($map, "AllParcels"), BufferGeodetic($feature, 50, "feet"))

var leng = LengthGeodetic($feature, 'feet')

var int_dict = {}

var xs = ""

for (var i in int_ma){

    var xs = AreaGeodetic(Intersection(buffer, i), 'square-feet')

    if(HasKey(int_dict,i.USE_CODE)){

        int_dict[i.USE_CODE] += xs

    } else {

        int_dict[i.USE_CODE] = xs

    }

var total = 0

var out_str = 0

for (var t in int_dict){

    total += sum(number(int_dict[t]))

}

for (var d in int_dict){

  var Ucode = decode(d,

  "0101", "Multiple-Use, Primarily Residential",

"031", "Multiple-Use, Primarily Commercial",

"101", "Residential, Single Family",

"102", "Residential, Multi-family",

"1320", "Residential, Vacant Land",

"140", "Residential, Other",

"300", "Commercial",

"3000", "Commercial",

"400", "Industrial",

"901", "Exempt Property",

'other');

  out_str += '\n' + Ucode + ' - ' +round(number(int_dict[d])/(total)*leng,2)+" Ft"

}}

return out_str

I think you need to change the decode to be decoding i.USE_CODE, as currently it's decoding the feature object itself? And you need to pass that decoded value into your dictionary not the i.USE_CODE, so something like this:

var buffer = BufferGeodetic($feature, 50, "feet")
var int_ma = Intersects(FeatureSetByName($map, "AllParcels"), BufferGeodetic($feature, 50, "feet"))
var leng = LengthGeodetic($feature, 'feet')

var int_dict = {}
var xs = ""
for (var i in int_ma){
  var Ucode = decode(i.USE_CODE,
  "0101", "Multiple-Use, Primarily Residential",
  "0102", "Multiple-Use, Primarily Residential",
  "0104", "Multiple-Use, Primarily Residential",
  "031", "Multiple-Use, Primarily Commercial",
  "0316", "Multiple-Use, Primarily Commercial",
  "0321", "Multiple-Use, Primarily Commercial",
  "101", "Residential, Single Family",
  "1010", "Residential, Single Family",
  "1014", "Residential, Multi-family",
  "102", "Residential, Multi-family",
  "130", "Residential, Vacant Land",
  "300", "Commercial",
  "3000", "Commercial",
  "302", "Commercial",
  "400", "Industrial",
  "4000", "Industrial",
  "901", "Exempt Property",
  "902", "Exempt Property",
  'other');
    var xs = AreaGeodetic(Intersection(buffer, i), 'square-feet')
    if(HasKey(int_dict,UCode)){
        int_dict[UCode] += xs
    } else {
        int_dict[UCode] = xs
    }
var total = 0
var out_str = ''
for (var t in int_dict){
    total += sum(number(int_dict[t]))
}

for (var d in int_dict){
  out_str += '\n' +  Ucode + ' - ' +round(number(int_dict[d])/(total)*leng,2)+" Ft"
}}

return out_str
