I am having problems getting data to align properly with basemaps layers. The image below shows the difference between roads. The black lines are my centerlines shapefile, which is fairly off from the aerial underneath.
The centerlines shapefile's coordinate system is GCS_North_American_1983 while the basemap is WGS_1984_Web_Mercator_Auxillary_Sphere. I have tried projecting the centerlines shapefile into WGS_84 to get it to better align, but I don't believe I have gotten the transformation correct. I have tried using WGS_1984_(ITRF00)_To_NAD_1983 and NAD_1983_To_WGS_1984_5 transformations without much luck.
My data is in western Pennsylvania. I am looking for any help I can get so these line up. I am pretty sure it is a coordinate issue rather than the data provider digitized everything like this.
I am looking for suggestions on what I am to do next.
