My situation is I am doing a project in western NY and we are under UTM 17N, but most of the data I have is in UTM 18 N because most of the state is in 18N, so the datasets I get from the state are in 18N. Now I went into ArcCatalog and changed the projection to 17N for the shapefiles, all of which is in NAD 1983. It made them the right scale, but they are about 200 miles apart, the 18N is on the west of the 17N now. How can I align these shapefiles? Should I give a higher or lower easting? if so, how is this done. or is there a tool for which this can be done?
Notes: I currently have vectors and Rasters in the map and will be transforming the vectors to raster later on when I have them overlaid correctly. I know how to georeference any raster dataset that may be incorrect. The problem right now is the vector layers. Both of the files say this below.
