I think that the site might be suffering from too much traffic at times. After I posted it on here I tried it and it wouldn’t work, I got an error message saying that I’d not given my address correctly despite it being exactly as I’d done it before, (one click when offered on my spellcheck bar). I wasn’t worried because I already have a screenshot from a previous time. A day later I opened the tab and the map with my 100km diameter circle was there, so much for the error message! It looks as though sometimes patience might be required.
I found the 1km radius map far more useful than the 100km one as I was far more likely to exceed the limit on my familiar walks around the block. There is only one reason that I will be going anywhere near the 100km limit and that won’t involve seeing any people. Unfortunately at the moment my destination still remains out of bounds even though it is just within 100km and unless the legislation is changed going there will prove to be a wasted journey.
Google maps and other online mapping apps give the crew’s flight distance to any destination you search for. The system Stella posted is useful because it gives you an instant picture of your limits. Lifting the 1km boundary will make a huge difference to my life as it will allow me to do the simple outdoor pursuits that were one of the main reasons that I chose to live where I live. I doubt that I will have any more contact with other people than I’ve had for weeks but it will be lovely to do proper walks and cycle rides not just the repetitive walks within a km of my house.
On a computer with a nice big screen, Google Earth Pro will do it. It’s best to first zoom in and mark your starting point by dropping a pin on it. Then zoom out roughly to where you estimate the circle of 100km is likely to be. Then click on the ruler at the top which wil open a small box where you need ‘Mouse navigation’ ticked in order to be able to move the map. Select ‘circle’ and ‘kilometres’. Then turn mouse navigation off, put the mouse over your start point pin and pull outwards until you get a 100km circle. Tricky with a phone I guess but in any case I prefer my computer screen to a fiddly phone. I also have a paper map now sporting a large roughly pencilled 10km circle.
