How do i embed this with mapped points into a website

YOU ARE A STAR - thank you

This is a great idea. Planning on cycling 50 miles per day for 3 days so looking at potential starting points around the periphery. Will then look at gradient/cycle paths/hotels etc. Cheers!

Use an application that can open KML files

I can't open a KML file. Doesn't seem to open in Word or Chrome...any suggestions?

Firstly, this is a great tool works as expected and is easy to use. The ability to undue or remove a point would be useful, as would a save function. You have the ability to save other maps but not this one. Keep up the good work.

would be great if you could create a driving time radius around a post code (approx.)
On 12th March 2019

Currently there is no planned date for it
By Free Map Tools on 3rd January 2019

I am just wondering when the planned date is for being to bulk upload postcodes as I have got a couple of things I would like to use it on. :)

Hi, when you say you cant plot ... what doesn't appear or doesn't work when you expect it to? What steps do you take?
By Free Map Tools on 8th December 2018

Has something happened.... I can't seem to plot any radius anymore?
On 7th December 2018

Can I print the map, when I try it just gives me a blank circle
By Chris on 29th October 2018

Hi, not sure what you mean? It does allow you to plot 1,2,3 ... postcodes and keep them all visible. Do you mean something else?
By Free Map Tools on 9th October 2018

ability to overlay plots from additional post codes would be very useful
On 7th October 2018

Hi Liz, it should work now...
By Free Map Tools on 5th October 2018

Hi - I am trying to print a map using your radius from a UK post code with a transparent fill and a red line but, it keeps giving me a blue fill with a red line. what am I doing wrong?
