About

An important feature of this distance calculator tool is that it 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.

Want to save your route? Try the Advanced Google Maps Distance Calculator

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 affected.

Options

Click [Clear Last] to undo the last marker placed

Click [Zoom To Fit] to zoom the map around all markers

Click [Clear Map] to erase all markers and start again

Use the Quick Find text box to quickly relocate the map

You can choose between miles and kilometers (km) for the Total Distance readout

Click [Show Elevation] to get a chart showing the elevation of your route

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 showing the Mary Peters Track in South Belfast. The reading shows 0.394km which is clearly a reasonable measurement for an athletics track.

Map showing the estimated distance between New York and Paris. All references that can be found suggest that this is an accurate measurement.

Map showing the Seven Mile Straight in County Antrim, Northern Ireland. This shows a reading of 6.910 miles.

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.

The map shows day and night on Earth and the positions of the Sun (subsolar point) and the Moon (sublunar point) right now.

= The Sun's position directly overhead (zenith) in relation to an observer.

= The Moon's position at its zenith in relation to an observer (Moon phase is not shown).

= Civil Twilight (lightest shade)

= Nautical Twilight

= Astronomical Twilight

= Night, no twilight (darkest shade)

Position of the Sun: Subsolar Point

On Saturday, November 25, 2023 at 17:54:00 UTC the Sun is at its zenith at

The ground speed is currently 433.71 meters/second, 1561.3 kilometres/hour, 970.2 miles/hour or 843.1 nautical miles/hour (knots). The table below shows position of the the Sun compared to the time and date above:

Position of the Moon: Sublunar Point

On Saturday, November 25, 2023 at 17:54:00 UTC the Moon is at its zenith at

The ground speed is currently 428.27 meters/second, 1541.8 kilometres/hour, 958.0 miles/hour or 832.5 nautical miles/hour (knots). The table below shows position of the the Moon compared to the time and date above:

The declination angle, denoted by δ, varies seasonally due to the tilt of the Earth on its axis of rotation and the rotation of the Earth around the sun. If the Earth were not tilted on its axis of rotation, the declination would always be 0°. However, the Earth is tilted by 23.45° and the declination angle varies plus or minus this amount. Only at the spring and fall equinoxes is the declination angle equal to 0°. The rotation of the Earth around the sun and the change in the declination angle is shown in the animation below.

This simulator models the motions of the sun in the sky using a horizon diagram, demonstrating daily and seasonal changes in the sun's position.

The upper left panel shows the horizon diagram visualization. This is a representation of the sky as if it were a large sphere centered on an observer (the stickfigure). The location and local time for this observer are set in the Time and Location Controls panel.

The General Settings panel allows one to show or hide various features of the horizon diagram, as well as controlling the behavior when dragging the sun disk on the horizon diagram.

When animating, this simulator can run continuously (as if in fast forward) or it can step by day. Stepping by day keeps the time of day fixed as the day of year changes. For example, one can use this mode to see the path the noon time sun traces over the year.
