Grid+ uses several files types to develop a grid for use in EFDC. The .gpp file is a Grid+ project file and saves all the different files the user has loaded, including the actual grid (.gpp), background maps (.JGW, .GEO), splines (.P2D). In addition, if the user has any overlays (e.g. shoreline files) or DTM (e.g. bathymetry XYZ data), the full path name is saved in the gpp file, so those annotation layers will be added to the display when the gpp file is opened.
Loading a Project File
To load a Grid+ project file (*.gpp), the user should click File menu then select Open Project (or use shortcut keys Ctrl+O), as shown in How to Load Project. The user should browse the Grid+ project file and then click the Open button, as shown in How to Load Project. After clicking Open button, the Grid+ will load all files, such as the actual grid (.gpc, .cvl), as shown in How to Load Project.
Another option is that the user can load the Grid+ project file by selecting the project file in the Window Explorer folder (LMC) then drag and drop the file into the workspace of CVLGrid.
