Distances From Point

Description

To start, click on the map once to plot the centre point then click one or more times to plot the destination points. The distance from the centre point to each of the destination the points will then be displayed below the map.

This distance calculator will use the "as the crow flies" distance.

How To Use This Tool

1. Zoom and drag the map to find the location of the centre marker
2. Click to place the centre marker
3. Zoom and drag the map to find the location of one of the destination markers
4. Click to place the destination marker
5. Repeat as many times as necessary
6. The distance for each path will be calculated then displayed below the map in the requested units. You can change the units at any time
7. Add as many points as required
8. You can also drag and drop the markers to move them after they have been plotted

Notes

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

Options

• Click [Clear Last Leg] to undo the last marker placed
• Click [Zoom To Fit] to zoom the map around all markers
• Click [Toggle Markers] to switch he markers on the end points on and off
• Click [Pan to My Location] to move the map to your location
• Click [Clear Map] to erase all markers and start again
• Use the Quick Find text box to quickly relocate the map or place a marker at a particular point
• You can choose between miles and kilometers (km), nautical miles, meters or feet for the distance readout

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.
