When it is selected, the Projection Settings form will appear as shown in Working with projection in Grid+. As mentioned in the Infor box below, The user is not able to change the coordinate system from this form as Grid+ chooses the WGS84 geographic coordinate system as a default setting. It means that when we create any files from Grid+ and then export them to external files, their coordinates are in Latitude and Longitude. Working with projection in Grid+ shows coordinates of a spline file when opening with the Notepad editor as an example. The first line of the file provides information on the coordinate system.

As a default setting, Grid+1.2 always works with the Geographic Coordinate System (GCS). It means that its coordinates are longitude and latitude. |

The projection settings cannot be changed. However, Grid+ allows the user to set or convert the coordinate system for each file layer in Layer Control. When we import external files such as grid, spline, and overlay files, the coordinates in these files are already in Latitude and Longitude, so they will be located in the right places in the online background map.
