The Export button provides a number of options as shown in 1149960298 . These options are described in the table below.
...
Export to EFDC: export the selected grid layer to EFDC input files. The three files produces produced are the corners.inp, dxdy.inp, lxly.inp. This 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.
