Distance. This uses the ‘haversine’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the points (ignoring any hills they fly over, of course!).

509. Calculate the distance between two coordinates by latitude and longitude, including a Javascript implementation. West and South locations are negative. Remember minutes and seconds are out of 60 so S31 30' is -31.50 degrees. Don't forget to convert degrees to radians. Many languages have this function.

Where: s is the geodesic distance along the surface of the ellipsoid (in the same units as a & b); α 1 is the initial bearing, or forward azimuth; α 2 is the final bearing (in direction p 1 →p 2); Note: Vincenty observes that eqn. (18) becomes indeterminate over equatorial lines (since cos²α → 0); in this case, set cos2σ m to 0 and the result is computed correctly.

Distance Between Cities. If you are traveling to different cities and want to calculate the distance between cities, you can convert the city name to gps coordinates and then use the distance calculator or just use the distance between cities tool.. Distance Between Addresses. To calculate distance between addresses, simply use the gps converter to convert an address to latitude and longitude ...

This calculator will find the distance between two pairs of coordinates to a very high degree of precision (using the thoroughly nasty Vincenty Formula, which accounts for the flattened shape of the earth). The "Draw map" button will show you the two points on a map and draw the great circle route between them. Lat., Lon. 1. initial. bearing.

There are a handful of useful tools on the GPS Visualizer's coordinate calculators & distance tools page. One of them calculates the distance between two points. It has the option to draw the points on the map with the Great Circle showing as well as the option to draw a profile and export the data.

This tool will help you calculate the distance between two coordinates or a single point and a set of coordinates. I built this primarily to make it easy to check if a Locationless (Reverse) Cache has already been found. Inputs can be in several formats: GPS Coordinates (like N 42 59.458 W 71 27.826 or 42.990967 -71.463767) Geocaching.com ...

Step 2: Finding Proper Power Source for the Microcontroller and LCD. I opened up the GPS and found a test point, V28A, which must be regulated power from the Li-ion battery (3.7V). The microcontroller, ATmega328p, on Arduino can run at 1.8 - 5.5V and the LCD, Nokia 5110 need 2.7-3.3V. So 2.8V is perfect for both.

The result of the geodesic distance calculation is immediately displayed, along with a map showing the two points linked by a straight line. Geodesic distance calculator. Our formula integrates the curve of the earth to calculate as best as possible the distance as the crow flies. It is extremely accurate, especially for shorter distances.
