can I bring forward a map from "Distance Calculator" to "Advanced Google Maps Distant Calculator"? I have the link saved from "Distance Calculator"
By jerry on 09/04/2014
No, this is not possible.
By Daft Logic on 02/04/2014
Can I get the distance between markers as well as total distance?
On 02/04/2014
Hi, I can't find my saved Routes. Does the system deletes them by itself?. my routes used to be there whenever I logged in.
On 27/03/2014
Could you an option to add a range circle? For example if I first click on the map, and then "Range Circle" and enter 800km, then it will show me a circle with that radius. Would be really useful.
By Gabriel on 26/03/2014
Hobbes, that is the latest version so it is fine. Can you try deleting your temporary internet files then load the page again? Let us know if it works or not please.
By Daft Logic on 23/03/2014
How do you get the version updates? I have routes of some of my runs and hikes saved here. But over the last little while I get no starting map even after logging in and the page never stops loading. It says(Last Updated 10th November 2013)so that might be the prob. When I click on one of my saved routes from before I still get no map pictured, that area is just blank. I think the problem is I have an older version?

Excellent tool - use it to measure my run. Helps in training and I recommend it every time I get a chance
By Al Macasaet on 06/03/2014
Congratulation, is very good!!!!!!
By Israel on 21/02/2014
Hi Marvin, this should now be resolved. If you use the format 40.4637628, -106.8722997 then the lat, long coordinate should be resolved
By Daft Logic on 18/02/2014
Reference my comment on 24/01/2014, the gps location offset problem is still there.
By Marvin on 15/02/2014
now web site
On 05/02/2014
Well done all at daft logic for making this tool available after google removed it. More power to you.
By metaljar on 04/02/2014
Hi Marvin, thanks for reporting. This should now be resolved.
By Daft Logic on 24/01/2014
Just an FYI, I use the site for pre-trip flight planning just to get a general idea of distances. Never typed in gps coordinates before, but had this experience: The regular Google map site nailed these coordinates (40.4637628 -106.8722997) dead on, but this site shows it 1.297 nm NNE of there. It's a VOR location.
By Marvin on 24/01/2014
great app for planning navigation route and trip
On 22/01/2014
Please add "Add a marker". Could mark (click on) 2 markers and then added marker would appear between them on the route. Thanks!
On 18/01/2014
Please add a 'stay logged in' feature to the site. I use the site a lot ... it would be nice :) Thanks!
On 18/01/2014
Great App. Would it be possible to also give azimuths at points?
By JTD on 31/12/2013
ok./ it show defrenses in gps cordinat on my phon and in map wich is correct and near to actuall position in earth is calculation base on utm data calculate
By hosen on 19/12/2013
Hi, when loading and plotting the point "53.34, 4.75", it plots an incorrect marker. I double checked with another site and it shows it somewhere else off the coast of Belgium. I noticed this occurs with other points that are over water. I ran into this issue when a distance estimater i coded up would be really off (usually ~700km) when one of the endpoints was in water. Land to land points are spot on. great tool otherwise.

I'm trying to get a route in place, and distance from starting point, I need to map out closer to farthest, how may I do so?
By bebevco on 08/12/2013
Hi, the Area Calculator does have a login option where you can save and load previously saved areas.
By Daft Logic on 02/12/2013
distance from fateh jang to islamabad. pakistan.
By fakhar iqbal on 01/12/2013
Please could we have an Advanced Area Planner too? (i.e. where we can save area calculations like we now can save route calculations) As ever, THANK YOU!
On 01/12/2013
Thanks for this very usefull tool. Especially for sailing planing.
