I'm unable to log in. I requested another password and still was unable to login using the password you issued to me. Is there a problem at your end?

excellent free tool to confirm distances between points.
On 05/10/2015
Hobbes, thanks for your feedback. Can you test again please?
By Daft Logic on 22/09/2015
Nope. Still the same. loads and loads and loads and... I can see my saved routes, so I even clicked on them to see what that would do, but no map comes up and its connecting...loading...connecting....loading never ending.
By Hobbes. on 11/09/2015
Hobbes, can you test it again please and let us know the outcome?
By Daft Logic on 10/09/2015
Yeah, I get this all the time too. Keeps logging in and no map comes up at all. I get a brief view of the world map if I click to leave the page! I am using firefox and cleared everything.
By Hobbes on 06/09/2015
Great tool, thank you ! The ability to insert a marker would make it even greater. A suggestion : when following an existing route on the map with the mouse, making the position visible on the elevation chart.

Subida al Cerro del Burro por el acceso desde calle 25 metros. Desnivel de ascenso = 80 metros.

I'm not sure if someone mentioned this, but it would be even more useful to me to be able to upload a KML and/or GPX file and have these calculations made. Also include elevation changes if possible as is done of another site.
By Steve on 31/07/2015
It would be very useful to have a table with distances between adjacent markers distance from each marker to the first and to the last marker. In any case your site is very useful! Thanks!

Hi Lynne, unfortunately this is not possible. Sorry.
By Daft Logic on 19/06/2015
Very useful tool. I am using it to present document to one of my clients. However is there a way of showing the post codes for the toggle markers, instead of/as well as the grid references when hovering over the marker?
By Lynne on 19/06/2015
An "are you sure" option on the delete button would be helpful for us click challenged folks - doh!
By DrGlitch on 16/04/2015
An option to show elevation in ft instead of meters would be nice.
By DrGlitch on 16/04/2015
The elevation feature is great! It would be nice to have the same functionality as the current distance measurement works in Google Maps. Specifically: - Clicking on an existing mark deletes it. - Clicking on a spot on a line in an existing route inserts a mark. - Distance displayed at every mark, especially.
By DrGlitch on 16/04/2015
Thanks for the update Marvin.
By Daft Logic on 09/03/2015
Sorry for delay; been out of town. All functions including saving and recalling routes are working fine now. Thank You. I use Windows 7 and Chrome.
By Marvin on 07/03/2015
There weren't any java script errors appearing in either browser. I've just checked it (at 00:30 GMT, 26/2/2015) and my saved maps are loading for me.
By CassidyGF on 25/02/2015
CassidyGF, can you see any JavaScript errors in your browser? Thanks
By Daft Logic on 24/02/2015
I've tested this on both Chrome and Firefox, and on two different computers on different op systems. I can log in, but I can't bring up anything.
By CassidyGF on 24/02/2015
Hi Marvin, is this still and issue? Which web browser are you using? Thanks
By Daft Logic on 24/02/2015
Hi CassidyGF, which web browser are you using? Thanks
By Daft Logic on 24/02/2015
I'm like the others; nothing is working for me, either. It doesn't seem to want to get out of the log-in state.
By CassidyGF on 21/02/2015
The last couple days the search and all general map functions work, but clicking on a saved route or clicking save new route do nothing. I have cleared my chrome history/cookies & restarted Chrome, but no change. Have used this app with Windows 7 & Chrome for years with no problems. Maybe the last Windows update??
By Marvin on 20/02/2015
Hi, can you try deleting your temporary internet files and then reload the page again?
By Daft Logic on 18/02/2015
I've been trying to use this site for the past 2 days, but the map has not loaded. Any ideas?
On 18/02/2015
Hi, Elevation should now work on the 2nd, 3rd click ...
By Daft Logic on 11/02/2015
Great app. The elevation button does not seem to work unless I reload the page. Thanks!
