Duplicate Value in Ng-repeat

enter code hereI have an ng-repeat in my ionic code. It gives me many duplicate values as the data is coming from CSV file. How can I stop this duplicate values from being shown ? Data shows XYZ values more than 5 times but I want it to be shown only once. 

      <select ng-model="srcstn">
        <option   ng-repeat="x in from track by $index " >{{x.source}}</option>
      </select>

This is piece of code where m getting all duplicate values at {{x.source}}. and x.source has station names

Try using 'unique'(aliases: uniq) filter in angular.filter module 

usage: colection | uniq: 'property'

you can also filter by nested properties: 

 colection | uniq: 'property.nested_property'

try

<select ng-model="srcstn">
        <option   ng-repeat="x in from |uniq:'source'" >{{x.source}}</option>
      </select>
