I needed to upload sewer lines and manholes to ArcGIS Online. The manholes zipped shapefile uploaded fine. The sewer lines, however are not. There are about 600 sewer lines, so the amount of data should not be an issue. Every time I upload to zip to ArcGIS Online the new layer is there, but there are no features! In the attribute table, I see all of my fields, but again, there are no features. What is the problem? This file was originally taken from CAD, then imported into ArcGIS Online. Every thing was perfect in ArcMap, so I don't understand what the problem is. Any suggestions? Does anyone have a similar problem?
