Lat Long Mode: In the Lat Long mode the latitude and longitude of points on the map can be obtained. When Lat Long mode is selected, several options related to the Lat Long mode appear in the map mode selection window.

Latitude: Latitude measures how far north or south of the equator a place is located. The equator is situated at 0°, the North Pole at 90° north (or +90°, because a positive latitude implies north), and the South Pole at 90° south (or -90°). Latitude measurements range from 0° to (+/-)90°.

Longitude: Longitude measures how far east or west of the prime meridian a place is located. The prime meridian runs through Greenwich, England. Longitude measurements range from 0° to (+/-)180°. Once Lat Long mode is selected the Lat Long options show up in the map mode selection window.

If you move the mouse out of map mode selection window it disappears and at the top left of the window two text boxes show the latitude and longitude of the cursor and the marker. If the hide marker checkbox is not checked in the map mode selection window then a standard Google™ map marker sign marks the location of the "marker".

Decimal and Deg Min Sec Representations: There are two ways to represent latitude and longitude magnitudes: Using decimal fractions for values smaller than one degree or using minutes and seconds. Map mode selection window contains a checkbox titled "Deg Min Sec". If this checkbox is checked then all values in the Lat Long mode would be shown using degree, minute, second representation.

Positive Negative and N S E W Representations: There are two ways to represent whether a latitude is north or south of the equator or a longitude is east or west of the prime meridian; by using negative and positive numbers or appending N, S, to the latitude and E, W to the longitude. Negative numbers for latitude signify south of the equator and negative numbers for longitude signify west of the prime meridian. Map mode selection window contains a checkbox entitled N/S/E/W that switches between these two representations.

The options for the Lat Long selection in the map mode box also include several buttons on the right side.

Go to Lat Long Button: "Go to Lat Long" button brings up a popup window allowing the desired location's latitude and longitude to be typed in. Once the latitude and longitude is typed in and OK is pressed the marker moves to the specified latitude and longitude and the map is centered at the marker location. Please note that only number representation of latitude and longitude works with this dialog box (deg, min, sec and N/S/E/W representations don't work). Furthermore, latitude must be between -90 and 90 and longitude must be between -180 and 180.

Move Marker to Address Button: "Move Marker to Address" button brings up a popup window allowing the address of the desired location to be typed in. Once the address is entered and OK is pressed the marker moves to the specified address if the map engine is able to find the address. Otherwise a message indicating the reason for failure is displayed. The process of pinpointing coordinates from address is called geocoding.

Get Marker's Address Button: Sometimes you may need to obtain the address of a location on the map. This process of determining the street address from geometric coordinates is called reverse-geocoding. To do this, drag the marker to the desired location and press the Get Marker's Address button. An information window displays the address if available.

Center Buttons: Center Map at Marker and Move Marker to Center buttons cause the marker to be displayed at the center of the map. Center Map at Marker button keeps the marker stationary and moves the map viewport to Marker's position whereas Move Marker to Center button keeps the map viewport stationary and moves the marker to the viewport location.
