Radius Around Point
You can use this tool to find the radius around a point on the map. First type in the radius required in kilometers or miles and then click on the map at the center of where you wish the circle to appear. You can then create as many radii as you wish.
Radius Around Point Map
[12th July 2018] Unfortunately, due to a large price increase in back-end services, we can no longer offer some features on this page or have had to use alternative providers.
- Type in a radius required in the Radius Distance text box above
- [Zoom and Pan to find the required area on the map then click on the map to draw a circle] OR [Type a location into the text box and click Draw Radius] OR [Input the latitude and longitude of the location in decimal format].
- Click as many times as necessary to draw multiple circles
- You can use the [Clear Map] button to erase all markers and radii and start again
Use the "URL to last radius" text box to find a URL that will show the most recent radius on this page when opened in a web browser. This URL can be sent to anyone if you wish to forward it on.
Google Earth KML Output
You can now export all the drawn radii on the map to Google Earth for improved display and printing. You must have Google Earth installed (or another application capable of importing KML files). You need to have a radius displayed on the map before the output will work. Please report any bugs.
The procedure to Export to KML is as follows:
- Draw one or more radii on the map as you see fit
- Once ready, click the [Generate KML] button. You will probably need to scroll down the page to find this!
- After a short delay, the KML file with download
- You can then open the KML file in application such as Google Earth
Currently, the KML will include:
- The same radius size and shape
- Transparency of 50%
It will not include:
- Shading colour (blue only, but you can change this once it is loaded into Google Earth)
- Line colour (you can change this once it is loaded into Google Earth)
- Line thickness (you can change this once it is loaded into Google Earth)
These features may be added later depending on feedback.
The CSV option allows you to upload bulk points to the map. To do this you must format your points using the convention of latitude,longitude,radius per line where latitude and longitude are in decimal format and radius in km. Make sure to strip out any whitespace. You can upload as many lines as you wish, however more lines will take more time and every web browser will have its limits on the maximum number of lines (hence circles drawn) before things slow to a halt.

I remember previously the radius was buffered and I could get the suburb post codes and names within in. However, I cannot find this feature anymore?

i am in a huge perdicament

Would be nice to be able to name each individual layer :)
Thanks so much for the tool!

Google appropriates so much data from us for free, they are returning less and less all the time!

I've appreciated the use of this site for years, and I realize it's been a tremendous value for free all that time. I have to say, though, that it is a terrible shame, and an almost crippling limitation now, that the site does not have functional access to any map visuals other than the darkened "promotional" features. I don't know how this gets solved, but I hope some kind of fix or resolution can present itself.

How does it work to draw a radius to a point and show the map?
On 1st November 2018
Are there any plans to fix the map loading issue? It seems to be working fine on the Measure Distance on Map tool, but it's been broken on the radius tool for weeks. Thanks!

Hi! I've been using this map for years to draw a radius around a location but now the map isn't loading ... please help!
On 19th October 2018
would be nice to draw a radius of a point and show altitudes of given radials (e.g. 4, 8, 16, 32) matching the circle
By John on 11th October 2018
Doesn%u2019t work with google maps right
On 8th October 2018
Which box? There are more than one box above... please stop being stupid.

I saw other pages asking the user for Google API Key of the user and then make the google request with the key of the user and show the map!
Maybe you can think about this...

What happened to this site?
On 2nd October 2018
Hi ~ is the "Search" function coming back anytime soon for drawing radius?
By Richard Fong on 1st October 2018
Amazing work. Cheers!
