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.

i need a circle aroun a point.??

is it possible to add direction as well ?
By GrumpyGrandpaGrae on 20/10/2014
Thank you so much for creating this resource! I use it before every UAV flight to ensure that I'm compliant with the regulations, and I agree with the last poster requesting an iOS app. I would gladly pay for an app like this that would calculate distance from where I am to another point on the map!
By Chris www.shotby.ca on 18/10/2014
Thank you for this! It is amazing. Keep up the good work. Are you planning on making an app for either IOS or Android? I was using this to find the distance between my house and the cell towers. I do not know if you can add cell towers into your program, but if you can that would be amazing. Keep up the good work!
By Steve on 15/10/2014
This is very useful tool for measuring distances and I'm very happy that someone has put the time and effort into this program, keep up the good work!

Great tool. I use it to plan pigeon races and for their training schedule.

From previous post, the area effected by the fire is in the mountains were there is sometimes limited roads and lots of open country. By using map with road distances in this situation and not as the crow flies, means giving one false data as to how close or far they are to the fire. 15 miles on a windy switch back 20MPH road can actually bE, for example 5 miles away.
By Shelly McCune on 17/09/2014
Using this link to direct mobile apps users needed in find as crow flies distance for a local fire in pollock pines, ca. Many apps and different OS do not have this feature. It is important to get accurate data to our community when there is a large scale fire effecting hundreds of people. Thank you for this resource. I know many will be directed here and find it useful, some life saving.

Amazing satellite imagery! The quality of the image seems nice and the features offered to this as well. Aerial mapping is widely used nowadays to provide a better quality of aerial image/map. Great work! Daniel - TerraServer

Super Coool But I cannot get the elevation thing to work. No big problem but it would be nice.
By Ajax One on 04/09/2014
this is wonderful
By Ali on 04/09/2014
it would be nice if elevation came up in feet, when you selected miles or feet as units. (it shows meters instead). Also be nice if it highlighted the elevation as you selected one of the pointers.

Mi ' stato di grande aiuto. Ho navigato da Seranda (Albania) fino a Crotone e non non avevo strumenti. Grazie

Hi, it isn't the straightest track I've ever seen! However, I think the mis-reading is due to the 45degree view. If you switch it off using the drop down menu at the top right of the map, it should be closer to 400m when you measure. Then, if you switch the 45degree view back on, you will notice the line is not longer on the same position on the track, hence the difference.

the address of the the running track is 1540 deerwood dr. eagan mn 55122

Hi, where is (address) the running track with the unusual measurement?
By Daft Logic on 31/08/2014
my name is aman I have a problem that it is not showing distances
On 31/08/2014
I have been measuring some running tracks in my area and the one I run on the most keeps saying 420 meters or .262 while others are the usual 400 meters. Could there be a difference because of a projected coordinate system or datum being off? Or is my main running track just long.
On 30/08/2014
Brilliant ... would you be able to indicate the 'heading' in degrees of the line between the two points?
By figflower on 29/08/2014
Cool
On 29/08/2014
cool. used it to calculate my running routes:)

Brilliant! My husband has a Garmin. I'd rather spend 100 on shoes & use this excellent tool
