Explain to me what happens for each overlay. Use maps as you feel necessary. Only those portions of the input coverage features falling outside the erase polygon outside boundaries are copied to the Output coverage. Use whatever commands you deem appropriate to fully understand what happened in these overlays. In ArcMap, create a map of the output coverage and include a description of explaining the results.
Attributes are updated and topology is rebuilt.
First you must make sure the polygon table structure for the two tables match exactly. All other items, including redefined items, should be dropped. Copy each frequency file to disk to pass in.
