Users that I work with are having problems using ESRI's ArcOnline Basemaps (specifically World Imagery Basemap) because the load and redraw rates are very slow. I have had them switch to the same coordinate system as the basemap (WGS 1984 Web Mercator, Auxiliary Sphere) and this usually resolves the problem. However, most of our working data is…(Show moreShow less)
