1.xx 3.xx 4.00

WINDOWS

= SUMMARY =

In Automap Road Atlas versions 1.x and 3.x, latitude and longitude coordinates, shown when you select the Track option from the Utilities menu, use degrees and minutes.

In Automap Pro version 1.x, the latitude and longitude coordinates used in the Database Editor use decimal degrees.

Microsoft Automap Road Atlas version 4.x can be set to use either degrees and minutes or decimal degrees.

= MORE INFORMATION =

The degrees and minutes used in Road Atlas versions 1.x and 3.x use the following format:

43’ 22.2&quot; N

where 43 is the Degrees and 22.2 is the degrees in minutes.

Automap Pro uses decimal format measurements, where 43’ 22.2&quot; N would interpret as follows:

43.37

where 43 is the degrees and 37 is the decimal minutes.

The formula used for Decimal Minute calculation is:

.37 = 22.2/60

NOTE: Special consideration should be given when using longitude coordinates. If the coordinate is globally west of the Greenwich Meridian line (for example, anywhere in the United States) the longitude coordinate needs to be negative number.

Microsoft Road Atlas for Windows version 4.0 may use either notation. You may toggle between decimal, and degree and minute. To change the notation, Click Tools, then click Track. After you select latitude/longitude, click Options.
