Can the Crowdsourced point information(location) be uploaded / consumed and used in a arcgis online web map?
Sorry about the delay replying. Yes, the content that is posted by the end users of a Crowdsource app is automatically stored in a feature service that is automatically created in the account of the creator/owner of the app. When you create a Crowdsource story, the Builder automatically creates this feature service and a web map displaying that feature service. You can therefore use that feature service in other maps and apps, and that map in other apps.
