This button is reset to a new project. It will clear The New Project button clears all the data in the workspace, and the user will start working with on a new project. | ||
The Load button will loads a project saved on the computer's hard drive or in some external memory. | ||
The Save button allows saves the user to save the entire project to one .CVP2 file.GPP file. This is a general layout file, not the grid file loaded into EE. | ||
The Import button allows to import imports external files (see below for details). | ||
The Export button allows to export exports the grid to different grid types (see below for details). | ||

The Import button provides a number of options as shown in 1149960298. These options are described in the table below.
Import Grid: open different types of the grid file as native grid type of Grid+, RGF grid, ECOMSED grid, SEAGRID, etc.
Import EFDC Model: open the EFDC input file (e.g corners.inp, dxdy.inp, lxly.inp)
Import Georeferenced Image: open a georeferenced background image (e.g *.jgw, *.geo)
Import Overlay: open an overlay file as shoreline, polyline, polygon (*.p2d, *.shp)
Import Splines: open the splines file (*.spl), this is a native file created from Grid+
Import Labels: open the label file (*.dat, *.p2d), this file has three columns. Two columns for coordinates (X, Y), and the third column is label names.
Import Cross-Sections: open the cross-section file (*.ldb, *.p2d), this file has three columns. Two columns are for coordinates (X, Y), and the third column is for elevation.
Import DEM: open the DEM (Digital Elevation Models) file (*.txt, *.asc, *.grd, *.tb2). DEMs are files that contain either points (vector) or pixels (raster), with each point or pixel having an elevation value.
Import Scatter Data: open the scatter dât file (*.xyz, *.dat) this file has three columns. Two columns are for coordinates (X, Y), and the third column is for elevation.

The Export button provides a number of options as shown in 1149960298 . These options are described in the table below.
Export Grid: export the selected grid layer to the native grid file of Grid+ (*.gpc), CVLGrid (*.cvl), Delft3D (*.grd), and others.
Export to EFDC: export the selected grid layer to EFDC input files. The three files produced are the corners.inp, dxdy.inp, lxly.inp. Doing this allows the user to edit a grid and then reopen it in EEMS without changing the boundary conditions. If the user wants to create a wholly new model, including the EFDC.INP etc, then that should be done in EE rather than in Grid+ .
Export to Shapefile: export the selected grid layer to the shapefile, which can open with ArcGIS, QGIS, Global Mapper, and others.
Export to KML: export the selected grid layer to the KML file, which can open with Google Earth, Global Mapper, and others.
Export Graphics: export the workspace to an image file with various file formats as *.png, *.jpg, and others.
