Pitney Bowes MapInfo Professional - Manual (Page 118)

• Military Grid Reference System - Choose this option to display your Map using the Military Grid
Reference System format. Coordinates are converted to the Military Grid Reference System format
using the World Geodetic System (WGS) of 1984 Ellipsoid.
• US National Grid Reference (NAD 83/WGS 84) - Choose this option to display your map using the
United States National Grid (USNG) reference system format. Coordinates are converted to the United
States National Grid format using the North American Datum of 1983 / World Geodetic System (WGS)
of 1984 Ellipsoid.
• US National Grid Reference (NAD 27) - Choose this option to display your map using the United
States National Grid (USNG) reference system format. Coordinates are converted to the North American
Datum of 1927 Ellipsoid.
To override a grid references system preference in individual maps, use the Map Options
dialog box (on the Map menu, click Options). Overrides to the default coordinate setting will
be saved to your workspace. Note:
Selected in either the Map window preferences or the Map Options dialog boxes, the format
will display in the status bar, but not in the Object Info dialog boxes. If you display any Object Note:
Info dialog box for an object on a map that uses the Military Grid Reference System or United
States National Grid, the coordinates will be displayed in decimal degrees.
Choose a Distance/Area using setting to specify the default type of distance and area calculation that
MapInfo Professional uses for new Map windows.
• 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.
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.
Adornments tab (Map window dialog box)
The Adornments tab on the Map Preferences dialog box has preferences for controlling how to position
a new scale bar.
The Adornment group of options set the defaults for how to locate a new scale bar on the map.
• Select a default position - Select to place adornment in a preset location in the Layout window:
upper left corner, upper right corner, lower left corner, or lower right corner.
• (Optional) Enter measurement values in to the X offset and Y offset fields. Use positive numbers.
• Specify a custom position (from top left) - Select to place adornment in a specific location in the
Layout window. Enter measurement values in to the Move right and Move down fields. Use positive
numbers.
• Background - Click these buttons to set the background fill style and background border style.
The Scale Bar Adornment group of options set the default style for a scale bar.
• Bar Length - The two values are proportional: the first value is the distance on the paper map, the
second value is what the first value represents as a distance on the Earth's surface. Specify the length
of the scale bar to a maximum of 34 inches or 86.3 cm on the printed map.
• Bar Height - Set the height of the adornment to a maximum of 44 inches or 111.76cm on the printed
map.
