If we eventually get stuck having to use AGOL/Portal (the web map route) for our WAB sites, are there any major benefits to change from your currently used coordinate system (State Plane GA West for me) to match the ESRI Basemaps?
Flex has never had a problem with the deviation between the Operational Layers and the Basemaps using the REST URLs. But before I go back and re-publish my services to Server, with the additional step of registering the service with AGOL, I'm wondering if I should reproject my services in the WGS 84 Web Mercator and match my scale dependencies to their Layer Levels? Btw, all of my services will be dynamic, no caching.
Anyone have any suggestions on this?
