GIS6005 - Module 2: Coordinate Systems

 

For this map, I used NAD 1983 Oregon Albers (Meters). There were multiple for the State, but I decided on this one. Oregon spans multiple state plane zones, so the state plane is unsuitable for Oregon’s statewide mapping. The state also crosses two UTM zones, which would distort if just one zone were used. For this reason, I used a custom statewide conic projection. Oregon is a mid latitude state with a strong east-west orientation, so the conic projection works well.
