Specifying Options in a Map - MapInfo_Pro - 2023

To specify units of measure in a Map window:

1. On the MAP tab, click Options, and Map Options to open the Map Options dialog box.
2. Choose a calculation method in the Distance/Area using group:
   • Spherical - Spherical calculations are used for distance methods that attempt to keep the measurement on the curved surface of the earth. The data is first converted to Latitude/Longitude and then a calculation is produced.

     Non-earth data cannot use spherical calculations, since the data cannot be converted to Latitude/Longitude.

   • Cartesian - Cartesian methods are used to perform calculations on Non-earth data. Cartesian coordinates are a pair of numbers, (x, y), defining the position of a point in a two-dimensional space by its perpendicular projection onto two axes that are at right angles to each other.

     Cartesian calculations cannot be used for Latitude/Longitude data, which is not a flat projection.

3. In the Map Units group, select the map units to use for the following:
   • Coordinate Units
   • Distance Units
   • Area Units
4. In the Display Coordinates group, select one of the following:
   • Check the Scroll Bars check box to show scroll bars in the Map window.
   • Check the Autoscroll check box to automatically scroll when using commands when no scroll bars are present in the Map window.
5. Click OK to close the dialog and save your settings.
