topic How best to deal with large feature layers in Developers Questions https://community.esri.com/t5/developers-questions/how-best-to-deal-with-large-feature-layers/m-p/834331#M5436 <HTML><HEAD></HEAD><BODY><P><SPAN style="background-color: #ffffff;">I'm currently working on getting data from a massive trail feature layer to map on an iOS app. In order to display the individual trails in different colors I thought to use the #iOS SDK filter functions to filter the data for each trails and display the filtered trail data as a different feature layer. The trail layer is massive so I see that this is taking the iOS app a sec to display the data. How do I do this filtering work remotely? Can I create new feature layers on arcgis from other layers remotely? Can this be done on a #ASP.NET Core webapp? Also generally what's the best way to deal with large data sets on mobile apps.</SPAN></P></BODY></HTML> Fri, 05 Jun 2020 01:33:09 GMT Anonymous User 2020-06-05T01:33:09Z How best to deal with large feature layers https://community.esri.com/t5/developers-questions/how-best-to-deal-with-large-feature-layers/m-p/834331#M5436 <HTML><HEAD></HEAD><BODY><P><SPAN style="background-color: #ffffff;">I'm currently working on getting data from a massive trail feature layer to map on an iOS app. In order to display the individual trails in different colors I thought to use the #iOS SDK filter functions to filter the data for each trails and display the filtered trail data as a different feature layer.

If you could do that, it would allow the community to give you better more specific suggestions.&nbsp;That being said, I'll take a stab at not&nbsp;directly answering the question you are asking. (Sorry I'm a data architect it's what I do.)&nbsp; Would it be possible to change the flow of the app so that&nbsp;the service doesn't have to return all of the data to your app? Maybe&nbsp;the default view could use the device location to show a map of just the trails that are in the area.&nbsp;Another a way might be to not show a map as the first page of the app, but to provide a search for individual trails, or states/counties to show a handful of trails at a time.</P></BODY></HTML> Tue, 09 Jun 2020 11:41:00 GMT https://community.esri.com/t5/developers-questions/how-best-to-deal-with-large-feature-layers/m-p/834332#M5437 PaulBrandt 2020-06-09T11:41:00Z
