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
About
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
