Specifies the latitude, longitude, and GMT offset by interactively picking a location from a world map.
A ToolTip displays the latitude and longitude as the bull's eye indicator 
is dragged across the map. When the bull's eye is released, the latitude and longitude
fields automatically update with that location's corresponding north/south and east/west
position (in degrees).
Latitude
Specifies the North/South position of the model's location in degrees. This position includes both a numerical value and a qualifier, either North or South. You can type values in these fields or use the bull's eye indicator on the map to specify the latitude. The current latitude and longitude are displayed in a ToolTip when the bull's eye indicator is dragged to a new location. Releasing the bull's eye indicator at that position will populate the Latitude and Longitude fields.
Longitude
Specifies the East/West position of the model's location in degrees. This position includes both a numerical value and a qualifier, either East or West. You can type values in these fields or use the bull's eye indicator on the map to specify the longitude. The current latitude and longitude are displayed in a ToolTip when the bull's eye indicator is dragged to a new location. Releasing the bull's eye indicator at that position will populate the Latitude and Longitude fields.
GMT offset
Specifies the difference between Greenwich Mean Time (GMT) and the time at the model's location. You can type in a value or use the Zone or Cities buttons on the Solar tab to pick the correct offset.
City
Displays the name of the city selected in the Cities dialog box or with the bull's eye indicator. If the bull's eye indicator passes over a city listed in the Cities dialog box, then the city name displays in the ToolTip beside the latitude and longitude coordinates. Releasing the bull's eye indicator at that position will populate the city field in addition to the Latitude and Longitude fields on the World Map dialog box.
The OK button on this dialog box populates the Latitude, Longitude, and GMT offset fields on the Solar tab with the values from their respective fields on the dialog box.
