I am currently trying to create a shapefile in arc map which displays the stikine to iskut rive in british columbia canada. Because, I have not been able to find one that already exists I was looking to create this shapefile from google earth and then convert it from kml to layer and export it as an shp. I have done this process before with building in google earth which are easy polygons to trace but I am not sure how to do this with an extremely long river that has curves and turns. Tracing with the polygon on google earth seems pretty jagged. Does anyone have any suggestions for this? Please let me know because I am stuck!
