I am working with a large shapefile (47MB) in ArcGIS online for using in my story map on the Visual Tab - link here: https://arcg.is/0b4LL . It a a zone of theoretical visibility (ZTV) for wind farms. I converted it from a raster and dissolved it and merged some attributes to make it smaller and easier to handle in Arc GIS online. I have also ended up splitting it into separate shapefiles as this seems to help a bit in loading.
I have shared it as a service to my account and I read this should make it quicker loading however i am still finding it very slow loading and when you zoom in to the map when the map is trying to load the whole site crashes!
I tried to publish so it is a host tile layer but when I add it to my map it keep saying there is an error and that it might not be in the right co-ordinate system. I did try and re-projecting it in the recommended WGS 1984 Web Mercator Auxiliary Sphere but it still comes up with the same error.
I also tried loading the raster by publishing it but had similar issues. Has anyone found a good way of loading large shapefiles?
Here is a link to the file I am working with: https://services7.arcgis.com/JTczPnyatlWnJ5Gc/arcgis/rest/services/Scenario_A_ZTV_groups/FeatureServ...
