The installation process does not offer to download any kind of products that are not actually necessary for the program to fully function, and it is over in a jiffy. Once you complete it, you come by what seems to be a pretty overwhelming interface, as it contains a lot of information, yet it is quite well-organized, presenting a menu bar, a few tabs and an interactive world map.
Furthermore, Help contents are provided, thus ensuring that both beginners and highly experienced people can find their way around it, without experiencing any kind of issues.
Types of calculations available
This software tool enables you to find out the shortest distance between two given points or cities, the end point, given start, direction and distance details, as well as the distance between two specified points along a line of constant bearing. It is also possible to find a circular coverage area, given a central start point and the radius.
View longitude and longitude coordinates and change the shape of the Earth
It is important to understand that all these calculations are made taking into consideration the Earth’s shape and you can select the points by simply clicking on the world map provided in the main window. In addition to that, the latitude and longitude coordinates of each point are immediately detected and displayed, while the results are displayed in miles and kilometers.
It is possible to calculate the distances between two major cities, by selecting them from a huge built-in list, the shape of the Earth can be changed from a WGS84 ellipsoid to a spherical Earth, and show or hide the latitude and longitude grid.
With an intuitive interface, good response time, minimal usage of CPU and memory and comprehensive Help contents, GreatCirc proves to be a pretty efficient and reliable piece of software, when it comes to making calculations on the Earth surface.

- Bug Fixes:
- Fixed bug where colours incorrectly read from KML file in Batch Mode.
- Fixed bug where altitude incorrectly read from GPX file. Note that GreatCirc does not use the altitude, but it preserves this information in Batch Mode in case the user saves to a KML output file.
- Fixed circle coverage labelling in Batch Mode.
