Description

You can use this 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 mileage 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 distance calculator 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 calculated then 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
  8. To share your route and distance calculation use the option [Generate Link For This Route]. You can then copy the link generated and send this via Twitter or Facebook.

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

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.
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.

This would be handy for antenna finding if you somehow got an azimuth reading between the two points.

Hi Lunar, Unfortunately this isn't possible to do with this page.

I has uploaded my route in google map. Like path A, B , C , D. So there is 4 place i have marked with balloon marker. there is a line cross each path. what I want is : if i put the distance, example 5 km, there will be show a marker between path A and B, if I put 10 km , there will be show a marker between B and C. Could you help me please?
By Lunar on 23/01/2015
Hi Gerry, the toggle markers option can be used to hide/show the markers. Does this help?

Hi Cory, please have a look at Google Maps Area Calculator Tool.
By Daft Logic on 21/01/2015
is there a way to calculate sq ft without having to measure each individual point?
By Cory on 21/01/2015
Hello, can you help me , how to make an input by metres, then can be showed the path at the map where the KML routed?
By lunar on 21/01/2015
guys please check NM ( 1852 km ) as i think it is not accurate here. must be a mistake as NM cannot be less in distance than a mile.
By lucas on 20/01/2015
very useful for planning walks however the marking points are too big and tend to obscure the roadway when close together eg at junctions. Suggest using smaller points as this would be more effective.Thanks

Update: this only works in Google Chrome all my other browsers the tools do not work.

I also no longer have the satellite view option nor the zoom or direction tools using Daft Logic... works fine on other Google maps.
By Steve on 14/01/2015
Hi Frank, do you see any javascript errors in your browser?
By Daft Logic on 13/01/2015
No satellite view either.
By Frank on 13/01/2015
The address search does not work, the co-ordinate search does. Although no zoom nor direction tools. My browser works fine with Goole Maps both search and zoom.
By Frank on 13/01/2015
hector, the drop down to choose between Map and Satellite should still be at the top right of the map.
By Daft Logic on 12/01/2015
i don't have a satellite option any more is this right?

Hi Russ, unfortunately this is not possible.
By Daft Logic on 31/12/2014
Thank you for developing this map tool! I have made a square area on the map and I have saved it. I would like to move that square to any point on the map. Do you know of any way that the square that I made can be moved to anywhere on the map? I'm guessing the answer is "no" but wanted to ask the master here. I may be missing something that might help make it happen. Thanks again!
By Russ on 31/12/2014
I love This Tool
