Table 4. Grid Indexing

Option	Description
Transpose I - J Indices	The I and J indices of each cell are switched.
Flip I Indices	Only I indices are modified while J indices are unchanged.
Flip J Indices	Only J indices are modified while I indices are unchanged.
Rotate Indices Clockwise	The cell indices are moved along clockwise.
Rotate Indices Counter-Clockwise	The cell indices are moved along counter- clockwise.

When a grid is generated each node has an I and J coordinate. This tool allows the user to reverse the I and J coordinates either separately, or at the same time using Transpose.

Export To

The grid cells can be exported to several file format as shown in Figure 7.

Option	Description
Export To Grid+	The file of the grid cell will has format *cvl
Export To RGF Grid	The file of the grid cell will has format *RGF
Export To EFDC Grid	The file of the grid cell will has format *inp, which can import directly to EEMS model
Export To Shapefile	The file of the grid cell will has format *shp
Export To KML	The file of the grid cell will has format *kml
Export To Outline	The file of the grid cell will has format *p2d
