Description

You can use the Google Maps Distance Calculator to find out the distance between two or more points anywhere on the earth. In other words, the distance between A and B. Click once on the map to place the first marker and then click again to position the second marker. The distance between the points will then be displayed. You can also build up a series of locations to find a total distance.

An important feature of this tool is that is "as the crow flies", so traveling in real life will normally involve larger distances, but this may also help those who need to measure off-road distances.

How To Use

  1. Zoom and drag the map to find the location of marker 1
  2. Click to place marker 1.
  3. Zoom and drag the map to find the location of marker 2.
  4. Click to place marker 2.
  5. The distance will be displayed below the map in miles or kilometers. You can change between miles or km at any time.
  6. Add as many points as required and the distance will build up.
  7. You can also drag and drop markers after they have been put on the map

Note

All distances are estimations so Daft Logic does not accept any responsibility that may arise when the value reported is incorrect.

You can move the markers after they have been positioned so you can modify you route on the fly and see how the distance will be effected.

Options

How it Works

Clearly you, the user inputs two 'points' that are used to calculate the distance. Calculating the "As the Crow Flies" distance is a matter of using Great Circle formula. Then the main problem is converting the Google Map unit to miles and kilometers.

The map will also automatically save your route in your temporary internet cookies so that you can return and see the route as you last left it. If you ever need to start from scratch then use the [Clear Map] button.

Benchmark Tests

Map between New York and Paris
Map showing the estimated distance between New York and Paris. All references that can be found suggest that this is an accurate measurement.
Seven Mile Straight in Antrim
Map showing the Seven Mile Straight in County Antrim, Northern Ireland. This shows a reading of 6.910 miles.
Map between Belfast and Dublin
Map showing the distance between Belfast and Dublin. As far as I can see this is an accurate estimate (if there is such a thing). This trip would be approximately 100 miles by road so the proverbial crow would have less distance to travel.
Mary Peters Track in Belfast
Map showing the Mary Peters Track in South Belfast. The reading shows 0.394km which is clearly a reasonable measurement for an athletics track.

Had to find out how many netres my property was from water for insurance renewal purposes- no problem on your site.

I use this tool for planning my open water rowing trips. It is a fantastic tool. Saving trip data to an account and import/export would be great. An iPhone app. so you can take a planned trip with you and record actual trip from GPS data would all be great features.

love this site, use it for home to boat ramp to fish distances.
By wormking on 30/01/2010
aaron, I am reluctant to add any more inline features such as extra measurements because I believe it is on the edge of being too resource heavy as it stands. However, exporting the data is something that can be added so I will look in to it%u2026 Thanks for the feedback.

not good maps u have

As I said before: GREAT tool!. Had a couple ideas for future improvements... 1) In addition to the waypoint markers, add toggle feature to display cumulative distance, true north heading and distance to the next waypoint, and elevation for each point along route. 2) Export waypoint file to excel (great for logging run, bike, orienteering times). As always, thanks for the great work!

used this for adog walk route excellent

Not bad! But add an elevation view from the two points with altitude change. I would like to know high points between the points for line-of-site for radio work. Amateur Radio!

superb.....

Fantastic utility! thanks so much!
By Russ hill on 03/01/2010
This is a great website and a great help. Have planned some spectacular walks for my wife and I, as well as some training routes for my sled dog team. Keep up the good work. Many thanks.
By Rigracer on 03/01/2010
Great tool! Will you allow the use of coordinates? This would be a great tool for geocachers to calculate the distant of one cache to another as they cannot be within .1 mile (528 feet of another cache.

thanks

Why don't you include info for the country of Israel???

Hi, Does anyone have any ideas about the formula or the algorithm used to calculate the road trajectory between 2 points on Mapquest or Google map? Thanks in advace ;-) John

Hey, just wanted to add that I like this site alot as well! I use it to check out distances on different runs. I don't like running the same routes every time, so I like to change, but need to know about how far each one is :) Thanks!
