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
- Type in a radius required in the 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, a blue hyperlink will appear below the button that reads [Download KML File Here]
- Click the hyperlink to download the KML file to your local machine
- 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.
..should add two radii around the Olympic stadium in London for 10km and 15km

monique, to start with can you see the map on the page? has it loaded?
If you type Seattle in to text box number 2 and click Draw Radius, what happens?
By Free Map Tools on 23/04/2015
No, I can't even get the first point. Help on how to get the first point would be great, I need to plot 3 points, one in Seattle, New York and Mexico city
By monique on 23/04/2015
Hi monique, is it working with one point?
By Free Map Tools on 22/04/2015

can i ask for the code on the "Radius Around Point"? I badly need it for our capstone project. :(

Hi AJS, please have a look at How Far Can I Travel.
By Free Map Tools on 08/04/2015
Apart from line colors, dashed line styling would be a nice addition.
would be awesome to have capability to draw radius based on road mileage. Meaning, if i am willing to drive  miles from a point how far can i go in all directions.

Hi, there is a Full Screen option if you expand the Map Options section.
By Free Map Tools on 03/04/2015
I would like to have option to see my map in fullscreen
I made three locations and yet I keep getting... Error, URL is too large! Try a smaller radius or use fewer radii.
Can this be fixed?
By Aaron Van Noy on 30/03/2015
You can print the map if your switch to full screen and take a screenshot
Why is there no search button? Why does it not draw the radius when I enter the km/miles? Why does not work at all?!!!!?????? Complete waste of time.

can you print map
By Waman Chashmawala on 18/03/2015
Hi Randy, Clear Map is found inside the Map Options section.
