I'm having a problem with mapping my x.y (long, lat) points on ArcGIS Online—I only have access to Online, not Pro or Desktop. I've checked my long/lat points against other sources (e.g. Google Earth) and they appear in the correct spot there, but when I upload them to my Online map (as a .csv file), they appear slightly away from where the point is supposed to be. Are there any thoughts on how to fix this?
N.b. I've checked past questions/discussions that seem to encounter this same issue, but none of the solutions work:
1) Here they recommend switching base layer to geographic-world-wgs1984, which I did (among other base layers) and still encounter the same problem.
2) Here the responder recommends changing data frame's coordinate system, but I can't figure out how to do that on ArcGIS Online—Google was no help here.
Any advice is appreciated!
