GenCade 2.0 Grid Point Attributes Dialog
There are a few things to take into consideration when defining the GenCade grid. The locations of the point of origin and ending point matter for the GenCade simulation to be successful. For GenCade, all references to "left" and "right", imagine the user is standing on land and looking out toward the water. The same goes for the grid orientation. The point of origin is the left-most location to be made available to GenCade.
For example, for a GenCade grid in the northern Gulf of Mexico (Galveston, TX), the point of origin (Begin point) will be on the right hand side of the screen and the End point will be on the left.
As previously noted, there can only be one Begin point and only one End point as defined by this dialog.
To create a new point, click the "Create Feature Point" tool and then click the appropriate location for that point in the main graphics window. You can create several new points before assigning a type to them. Each newly created point will default to be an "Unassigned" type. No points that remain "Unassigned" will be considered in the grid generation process.
To define the type for the point, change to the "Select Feature Point" tool and double-click a point, or select multiple points you wish to assign the same type too and right-click then select "Assign Point Type...". A combo box (shown in Figure 1) on the resulting dialog will have several options to choose from:
- Unassigned
- Begin
- End
- Refine
If Refine is chosen, then an entry box will appear for the user to enter the resolution to be considered for that point (or point's) location. The resulting dialog for the Refine option is shown in Figure 2.
