Pitney Bowes MapInfo Professional - Manual (Page 425)

To set the type of distance and area calculation to use:
1. Select Options > Preferences > Map Window.
2. In the Map Preferences dialog box, select the Projection tab.
3. In the Distance/Area using pane, either of the following:
• Spherical - The Spherical calculations measure distance according to the curved surface of the
Earth. Spherical is the default. The data is first converted to Latitude/Longitude and then a calculation
is produced. Lat/Long data will always use spherical calculations.
• Cartesian - The Cartesian method performs calculations on data projected onto a flat plane.
Cartesian coordinates (x,y) define the position of a point in two-dimensional space by its
perpendicular projection onto two axes which are at right angles to each other. Long/Lat projections
cannot use Cartesian calculations.
4. Click OK to save your setting.
To specify a calculation method for the currently active Map window, use the Map Options dialog
box (on the Map menu, click Options). Note:
For more information about map preferences, see Setting your Map Window Preferences in the Help
System.
