SMS:Raster Module Interface

Clicking the raster module icon in the module tool bar will bring the raster module interface to display on the screen. The raster module interface can also be brought to display by clicking on a raster item in the project explorer. The raster module interface consists of the menu, tools, and project explorer right-click menus.

Raster Menu Items

The menu bar that appears in the Raster Module:

• File – Has standard features as in other models.
• Edit – Has standard features as in other models.
• Display – Under the Raster tab in Display Options, a user can choose to Display as raster or Display as surface. Display as raster is a 2D representation, while Display as surface uses data from pixels as elevation to show a 3D surface. It should be noted that these display options affect performance. Display as raster takes less memory and performs faster because it is a more efficient data structure. If Display as surface is selected, the user will be able to turn on or off contours, edges, or boundaries.
• Web – Has standard features as in other models.
• Window – Has standard features as in other models.
• Help – Has standard features as in other models.

Raster Tools

The Raster Module contains only one dynamic tool called the Select Points tool. Using this tool, one can edit/select one or more corners (points) of the pixels which make up the raster. Selecting cells with the Select Points tool will show information about the points in the status bar.

Right-Click Option

When one or more points are selected, one can right-click in the graphics window, and the option to convert selected raster points to a scatter set appears. If this option is clicked, a new scatter set will appear in the project explorer.

Raster Right-Click Menus

Right-Click Menu of "Raster Set" Project Explorer Item

Right-clicking on the raster item in the Project Explorer will bring up the following options:

• Delete – deletes the current coverage.
• Rename – lets user rename the current coverage.
• Options – Clicking this will bring up a raster options dialog. This allows a user to specify if the z values are elevations. If NCLD land data is being used, the user should specify that raster values are not elevations. Then if a user were to change projections, the z values that store the land data would not be affected.
• Interpolate – Data from raster sets may be interpolated to already existing TINs, meshes and 2D grids.

Right-Click Menu of "Raster" Project Explorer Item

Right-clicking on the raster item in the Project Explorer will bring up the following options:

• Delete
• Rename
• Convert – SMS allows rasters to be converted into TINs.
• Zoom to Raster

Right-Click Menu of Dynamic Tools

See Raster Tools above.
