Use the ranger finder tool to find out the end point on a map when you specify a start point, a bearing and a distance.
Range Finder Map
|Initial bearing from north deg|
How to use the Range Finder Tool
- Type in a required bearing (between 0 and 360 degrees) from north
- Type in the distance of the range to find in kilometers
- Click on the map to specify the base point
- The end of the range will then be displayed
- You can click over and over to specify more than one base point
- Click clear map to clear all markers from the map
Please note that the range finder tool uses great circle distances. This means that on this flat map the expected end point may not be exactly as you expect on screen especially over large distances, but this is a truer estimation of the actual end point in real life.
Future Ideas and Features
- Option to use the resultant point as the start of the next calculation without having the click back on the map. This allows a multi-path route to be plotted.
- Create an on-the-fly log of this route in text format
- 17th February 2016 - Both points can now be moved and the bearing and distance will update accordingly
- 16th February 2016 - Code updated to fix bugs. New option to display a line between each point. Map automatically zooms to fit both points
- 11th November 2013 - Implemented Google Maps API V3
- 16th October 2007 - Basic version with bearing (deg) and distance input (km)

Hi Tew Han Kiong, so you wish to input the points using latitude and longitude?

Can we find our point using coordinates?

Thanks for the feedback Kim

Very helpful map tool!
1. Map refresh is not complete when Medium or Large are selected.
2. The margin used for scroll activation is too large - you should allow the cursor to move closer to the edge of the map.

i suggest that you should also include a "spread" function for broadcasting ideals please. and also if you could fill in the spread with color or outline, and allow it to be resizable via click

Suggest coordinate entry for starting point.

Driving long distances over multiple days, might be useful to be able to plot circle ranges over multiple days, such as on flying maps.

Even without being able to click on an endpoint, it's sufficient to try a few numbers and refine a guess at a bearing. (This was the first thing I found when attempting to figure out from a photo where a lightning strike might have been...) Thanks!
