Professor Emeritus of Civil and Environmental Engineering San Diego State University, San Diego, California
1. INTRODUCTION In this article, we demonstrate the use of the online calculator ONLINEGEODISTANCETWO to evaluate the distance, as the crow flies, between two arbitrarily selected geographical locations A and B on the Earth's surface, each properly identified by their respective coordinates: Latitude and longitude. We describe the use of the online calculator by means of a clear example.
2. PROCEDURE The procedure consists of the following steps:
3. EXAMPLE This section provides an example of the use of online_geodistance_two. The objective is to calculate the distance between Heathrow airport, in London, United Kingdom, and Charles de Gaulle airport, near Paris, France. The geographical coordinates are obtained using Google Earth as follows:
A. Heathrow airport: Latitude 51° 28' 04" N, Longitude 0° 27' 18" W. The spheroidal geodistance between Heathrow (London) and Charles de Gaulle (Paris) airports is: 311,449.717 m, or 311.450 km.
4. CONCLUDING REMARKS We have used the online calculator ONLINEGEODISTANCETWO to determine the distance between Heathrow airport, in London, United Kingdom, and Charles de Gaulle airport, near Paris, France. This online tool may be used to determine the geodistance between any two locations on the Earth's surface, once the geographical coordinates are known. |
