Changing Projections in ArcMap Egeo 250 1ArcMap setting a projection

Investigating Projections Through the help commands you can learn more about projections and how the are created. 2ArcMap setting a projection

Open the properties for Layers 3ArcMap setting a projection

Under the Coordinate System Tab, Choose the Predifined coordinate systems 4ArcMap setting a projection

Global Projected Coordinate Systems 5ArcMap setting a projection

We will be using Projected Coordinate Systems 6ArcMap setting a projection

For World Data use a World Projection 7ArcMap setting a projection

Try a Mercator (Coast Lines & Direction) Projection 8ArcMap setting a projection

Miller Cylindrical (Direction) 9ArcMap setting a projection

Mollweide (Area) 10ArcMap setting a projection

UTM 11ArcMap setting a projection

ZONE 10 is the correct UTM zone for Whatcom County and Western WA 12ArcMap setting a projection

State Plane: Use either NAD 1927 or ArcMap setting a projection

We are in Washington North 14ArcMap setting a projection

To find true distance on the face of the earth use a Great Circle Measurment 15ArcMap setting a projection Note that this web page uses N/S on Lat and W/E on Long ESRI uses +/- for N/S and -/+ for W/E you need to make these adjustments
