Distance between Two Locations

This Application is based on Google Maps application program interface. It acts similar to a measuring tape to measure the geo distance between two points. But in this case on Google maps.
Locations are identified by marker positions.

The staring point takes a default position in Cairo, Egypt when you start.
It is represented by the blue marker.Blue Marker
You can drag it to the chosen position. The Latitude and Longitude will be updated accordingly

The Ending point is generated upon clicking on the map at the required position.
It is represented by the red marker.Red Marker
To tune up you may zoom and drag the marker to the required position on the map. The Latitude and Longitude will be updated and shown in corresponding text fields below Google map

The Geo distance will be shown in the info window on the
Also it will be shown in the text box below Google map.
It will be updated as you drag either of the markers. (There can be a delay of a few seconds for the update to populate)

The e-Measuring Tape application measures Geo distance between two points on Google Maps by applying the 'haversine' formula to calculate the great-circle distance between the points – that is, the shortest distance over the earth’s surface.

You can select the unit of measurement either km or miles.

The Tool is absolutely Free to use.

Haversine Formula

The haversine formula used in this application is an important equation in navigation. It gives the great-circle distances between two points on a sphere. It uses the longitudes and latitudes of the points as input.


Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Points with the same longitude lie in lines running from the North Pole to the South Pole. By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, was intended to establish the position of zero degrees longitude.


latitude is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. Latitude is an angle which ranges from 0° at the Equator to 90° (North or South) at the poles.

Geographical Distance

Geo - standing for Geographical - distance is the distance measured along the surface of the earth.
