The latest update for the area measurements is not very useful. You can no longer create new areas and combine the totals. Is there a way to use the previous tools?

Daftlogic area map is great for getting a quick measurement. The map tools have changed and no longer works? Wondering if this is an issue being fixed or if it%u2019s permanent?
Hope they go back to the previous map and tools

I have used this for years to map runs and walks, depending on my capabilities. It has contributed significantly to my health. Thanks!

Why is it when you click 'see all comments' on any of your pages it loads up the field to post a comment but shows no comments of others?

WWWhat happened to the height above sea level page? I liked finding out how high I was, as well as many other lowcations. I was quite surprised to find out my house, and so many other SIGNificant places are 666 feet above sea level. I may have to invest in one of those gadgets you can take with you, because I really want to find out how high "they" where when they had the first Catho Lick mass here in Onterrorio, 1615, at a place called Carhagouha, not far from where I exist. Ps, how are things at the Lodge?

What happened to street views (where available) related to markers? I enjoyed views along city streets/highways using gps marker coordinates. We seem to have regressed from a perfectly good program. Too bad.

Very helpful estimating land area specially for someone like me who eyes for buying a piece of farm property. Greetings from the Philippines & Saudi Arabia.

I wish that the satellite mapping process was repeated every year always instead of once every 1 to 3 years. Regardless to how much older images taken from the streets would be. For more than a year, I can't tell when new houses, etc are developed in a particular side edge of a city where I'm from but can't go visit. Mainly nearing the mountains finally. But not all are built side by side. So I'm anxious to see if the development has extended another mile or 100 yards or so. So I check time after time, waiting, but can't ever tell whether development has stalled, or if I'm looking at the same mapping from more than a year ago.

denzil, it isn't possible to adjust the pop-up behaviour. It is decimal degrees, so [lat, lng]. We have reduced the number of decimal points on the display as it was far to precise for its purpose. This will make the job of noting the location simpler.

I am using the 'distance calculator' program. Also is the readout in deg/mins/secs?. thanks for an early response. denzil feb 21/2018

Hi Denzil.
Which page on Daft Logic are you using?
By Daft Logic on 12th February 2018
a fantastic program which I have been using for many years. would it be possible to show longitude/latitude by the marker point for as long as takes for the user to copy. also are the values in degrees/minutes/secs.

Hi, the rotate option only appears at certain times. You need to be looking at an area with the correct imagery available. Then get zoomed in close enough for it to become active. Large cities are the most common place it works.
By Daft Logic on 31st January 2018
how do i get the rotation button to pop up to rotate buildings for side views? I've zoomed in like online videos tutorials show and it's not working. Thanks
