Grid+ can load the native grid file as *.gpc. Besides, it can load other types of grids, such as *.cvl (grid file made by CVLGrid) and *.grd (grid file made by Delft3D). To load a grid file, the user clicks Import file button from the main toolbar then select Import Grid, as shown in How to Load Grid.

Once selecting the Import Grid option, an Import Grid form will pop up, as shown in How to Load Grid. We browse to the grid file. We can select many types of grids by clicking on the down arrow in the form. After selecting a grid file, we click the Open button to load the file. After clicking Open button, the Coordinate System form will display, as shown in How to Load Grid. We should define a proper coordinate system for the grid. It could be a Geographic system or a UTM system and then click the OK button. If we select the wrong coordinate system, the grid will be located in the incorrect place, so we have to load it again with another coordinate system.

Another option is that you can load the grid file by selecting the grid file (LMC) and then drag and drop the file into the workspace of Grid+.
