Question 1.3:
(1 point)
Why can’t you just use the “project” option to fix the coordinate info for the areawater layer like
you did for the airports layer?
(hint:
think carefully about what “project” is really doing).
The "project" option in ArcGIS does not just change the coordinate system of a layer. The
areawater layer is in an undefined datum, which means that it does not have a defined
reference point
Question 1.4:

Which symbology did you choose for each of the following for your new map of Mahoning
County?
Airports (complexes)
Airport
Airports (runways)
Circle 3 (40%)
Areawater

Roads
Ramp
Structures (Education)
Triangle 1
