How to Obtain Latitude and Longitude

The latitude and longitude coordinates are used to plot the location on a map. Latitude is the number of degrees north or south of the equator. Longitude is the number of degrees east or west of the Prime Meridian. The Prime Meridian is an arbitrary line drawn from the North Pole to the South Pole running through the Royal Greenwich Observatory in Greenwich, England.


This database stores latitude and longitude as two decimal numbers. The whole number portion is the degrees and the fractional portion of the number is the fraction of degrees. Enter the coordinates in decimal degrees; there is no need to enter the direction (“N” or "W") Example 35.152/-85.29. CWBFM will edit the latitude to insure that it is between 25.00 and 47.50, the longitude must be between -111.55 and -75.50.


If you have a Global Positioning Satellite Reviver (GPSr), you’re all set. Create a Waypoint when you're there and later recall it and just type in what you see on the screen. Also, most cell phones know where they are and some may be able to display latitude and longitude. If your GSPr does not have a waymarking feature, it may have a “were am I” feature you can use to get the coordinates of the monument. If you do not have a GPSr, there are several alternatives.


A. If you have a smart phone, you may be able to download an app that will display the coordinates. Most Smartphone record the latitude and the longitude of where you were standing when you took the picture. There is software available to display the data that your Smartphone attaches to your pictures.


let you move the pushpin on the map to the exact location of the marker. iTouchMap will also display the coordinates in the decimal degrees format.


  1. Type, for example, “dennison & goodale st, columbus oh", click "go" and a pushpin will appear where the streets cross.
  2. Resize your map if necessary, then move your pushpin to the sidewalk where the marker is located.
  3. Remember to click on the pushpin once it is in the correct position to display the text balloon that shows the new latitude and longitude.
  4. Then copy both numbers at once using your mouse and keyboard, return to the CWBFM page and paste them both in the latitude field.
  5. Finally, cut the second number from where you just deposited it and paste it into the longitude field.
