Map Viewport Properties Dialog Box, General
Select General on the Map Viewport Properties dialog box to change the coordinate system, the projection, and the boundary options.
Options
Coordinate system
Indicate the type of coordinate system that the map data uses.
Planar Choose this option when map data is in X and Y coordinates, for example, for building plans.
Geographic Choose this option when map data is in longitude and latitude coordinates, for example, for city locations.
Projection
Specify the method to use to project geographic coordinates onto a two-dimensional surface. Choose a projection that is compatible with the data that you are visualizing. The four spatial properties that are affected by projection are area, shape, distance, and direction. For views of the earth, a good choice of projection depends on the center view, the map boundaries, and the zoom factor.
Each of the following projections preserves one or more of these spatial properties:
Equirectangular Choose this option to use longitude and latitude as rectangular coordinates.
Mercator Choose this popular projection for smaller areas, for less distortion around the equator, or when you want to add a map layer with an existing tile layer that uses the Mercator projection.
Robinson Choose this option for less distortion of large areas that span from the equator to the poles. Developed by Arthur H. Robinson in 1963.
Fahey Choose this option for less distortion of large areas that span from the equator to the poles. Developed by Lawrence Fahey in 1975.
Eckert1 Choose this option to use equally spaced parallels in latitude and straight lines for meridians in longitude.
Eckert3 Choose this option to use equally spaced parallels in latitude and curved lines for meridians in longitude.
HammerAitoff Choose this option for polar maps or world maps.
Wagner3 Choose this option for world maps.
Bonne Choose this option to view the world as it appears in an atlas.
