The Figure 1 shows RMC's options of a grid layerThe grid layer has a range of special options that are accessed by RMC on the grid title in the tree view (Figure 1). These options are summarized in the Table 1.

Grid Properties

RMC on the grid layer, then select Properties, and the Grid Properties will be displayed, as shown in Figure 2. The options here include:

  • Layer Name: show the name of the layer, a new name can be entered here
  • Layer Visible: unchecking this box will hide the grid layer ( the light bulb of the layer in the Control Panel is also turned off)
  • Show Lines: unchecking this box will hide the gridlines but sill other show properties of the grid e.g. Orthogonal Deviation. This is demonstrated in Figure 3.
  • Line Settings: allows the changing of setting style, color, and thickness of the gridlines.

Cell I,J IndicesShow the I and J indices number of the grid cells, each cell has a pair of I and J indices. (Figure

the next grid
a new grid that we want to merge with the previous grid
as we want
. In this case, we need to know the number of cells along a segment of the previous grid.

Grid Indexing

When a grid is generated each cell or node has an I and J coordinate. Sometimes these are not in the direction that the user requires. The Grid Indexing tool allows the user to reverse the I and J coordinates either separately, or at the same time.

To display the I, J labels of the grid, select the grid layer in the Layer Control then RMC. Select Show Labels (e.g Cell IJ Indices) as shown in Figure 10

Grid Indexing includes a number of options that are summarized in Table 4:

OptionDescription
Transpose I - J IndicesReverses both the I and J indices of the selected grid at the same time.
Flip I IndicesReverses only the I indices of the selected grid.
Flip J IndicesReverses only the I indices of the selected grid.
Rotate Indices ClockwiseOrders the indices in a clockwise direction.
Rotate Indices Counter-ClockwiseIt is the opposite of the Rotate Indices Clockwise.


Export

...


EE10 allows you to export the 2DH View of the current layer for post-processing.

To export the layer, the user needs to Right Mouse Click (RMC) on the layer and select Export to as shown in Figure 1. The Save Data File will be displayed, the user should specify the type of the file and click OK.

...

The Export option allows the saving of the grid to a file. A range of different file formats are supported as shown in Figure 14 and further summarized in Table 5. The function of these options is similar to the Export button described in Main toolbar buttons.

OptionDescription
Export To Grid+The file of the grid cell will has format *cvl Export To RGF GridThe file of the grid cell will has format *RGF Export the selected grid layer to an external grid file. Grid file formats can be a native file of Grid+ (*.gpc), CVLGrid (*.cvl), Delft3D (*.grd), or others. This option also can be accessed from the Export button in the main toolbar.
Export To EFDC GridThe file of Export the grid cell will has format *inp, which can import directly to EEMS modelselected grid layer to an EFDC input file (including corners.inp, dxdy.inp, lxly.inp). These files can open with EEMS.
Export To ShapefileThe file of Export the grid cell will has format *shpselected grid layer to a shapefile which can be opened with ArcGIS, QGIS, Global Mapper, etc.
Export To KMLThe file of Export the grid cell will has format *kml
Export To OutlineThe file of the grid cell will has format *p2d

...

selected grid layer to a KML file which can be opened with Google Earth, Global Mapper, etc.
Export Outline

Export outline of the selected grid layer to a text file (*.p2d).


Once selecting the Export Grid option, the Export to Grid form will be displayed, as shown in Figure 15. Define the file type from the drop-down list then enter a file name. Define the folder location to locate the file then click the Save button. Then the Coordinate System form will pop up, select the proper project then click the OK button as shown in Figure 16. When the exporting is done, a message will pop up as shown in Figure 17, click the OK button to close the form.
