How to Use

please tell me the gps point format for using area calculator. sample please thanks

Daftlogic, ex: 50°6'48.58",-111°58'18.93" If I use the search (above the map), it'll set it to the correct location. If I use "add manually" it's quite a ways off. I've crossed referenced with maps.google.com. The search function hits correctly. Manually adding points does not.

how to get distance between two pointe of triangle ? i only get total perimeter
By steve on 16/11/2014
Hi Matt, can you give an example of coordinates that don't give the desired result?
By Daft Logic on 16/11/2014
There's an issue with adding points. Or at least, I'm having an issue. Search for location seems to be accurate, but when adding points manually (with coordinates) it's way off.

Hi Alan, if you wish to measure distances, we recommend you use the Distance Calculator. This area calculator will only output the perimeter of the area being measured.
By Daft Logic on 09/11/2014
This is giving inaccurate results for me, twice those of Google's built in measuring tool. Google makes a car 3.5 metres long. This tool makes it 9. If this could be recalibrated it would be extremely useful

Great tool thank you. Is it possible to see a scale on the plan created or measure the length of part of the perimeter (I can see the total perimeter, but would like to quantify sections of it please)

Hi, are you using this area measurement tool to measure distances? It does display the perimeter of the areas drawn and for a 2 sided area, it will be twice the distance between the points.
By Daft Logic on 04/11/2014
Measurments were way off for me- around 2 to 2-1/2 larger. I checked against a car ~14' long. Tool measured it as 42 feet long. Youngstown OH area.

Hi Bruce, it centers the map on the address and doesn't put any markers as they may get in the way of the area being drawn.
