In the Terrain Data module, TINs and DEMs are listed in the Project Explorer. A toggle is next to each object; the toggle controls the visibility. The display is automatically updated when the toggle is checked or unchecked.

Right-clicking on the main Terrain Data folder Terrain Data folder icon in Project Explorer.png allows creating a New folder or TIN. Because TINs can be created by digitizing in WMS, a new, blank TIN can be created. However, DEMs are only created by opening a DEM file type. If neither a TIN nor a DEM exists, then a Reprojection can be performed on any existing terrain data. There is also an option to open a digital elevation file. Opening a digital elevation file using this option will open an elevation grid as a WMS DEM.

TIN Object Right-Click Menu

Right-clicking on a TIN allows selecting any of the TIN processing or visualization options in WMS. The commands in this menu are as follows:

TIN object right-click menu
  • Trim: Opens the Polygon Selection Options dialog.
  • Merge: Opens the Merge TINs dialog.
  • Filter: Brings up the Maximum filter angle dialog.
  • Fill:
  • Data: A submenu for adjusting datasets in the TIN. It contains the following commands:
  • Calculator: Launches the Data Calculator dialog for modifying or creating datasets in the TIN.
  • Smooth Dataset: Rounds the data values and creates a new dataset under the TIN with the smoothed values.
  • Map Elevation
  • Film Loop: Starts the Film Loop Setup dialog for creating a animation from the TIN.
  • Vertices: A submenu for adjusting vertices in the TIN. It contains the following commands:
  • Lock/Unlock
  • Delete Duplicates
  • Smooth Pits
  • Transform
  • Triangles: A submenu for triangulatin options in the TIN. It contains the following commands:
  • Triangulate
  • Insert Breaklines
  • Optimization Triangulation
  • Check Long/Thin Triangles
  • Remove Flat Triangles
  • Interpolate: A submenu for interpolating the TIN data to another module or TIN. It contains the following commands:
  • To 2D Grid
  • To TIN
  • To Feature Objects
  • Convert: A submenu for converting the TIN data to another module or DEM. It contains the following commands:
  • TIN Contours→Feature
  • TIN Boundary→Feature
  • TIN→2D Scatter Points
  • TIN→DEM
  • Projection: A submenu for changing the coordinate system of the TIN. It contains the following commands:
  • Projection
  • Set as Display Projection
  • Reproject
  • Transform
  • Options: Brings up the TIN Options dialog.
  • Import Scalar Dataset: Imports a scalar dataset by first selecting the type of scalar dataset to import and then launching the Open dialog.
  • Save As: Used to designate the path and prefix file name for saving a TIN.
  • Properties: Brings up the Properties window for the TIN.
  • Display Options: Brings up the Display Options dialog.
  • Delete: Removes the TIN from the project.
  • Duplicate: Creates a copy of the TIN.
  • Rename: Lets the name of the TIN be changed in the Project Explorer.
  • Zoom To Layer: Will resize the TIN data so it fills the Graphics Window.
  • Metadata: Brings up a Metadata dialog.
  • Generate Metadata XML From XMDF
  • Compute Area Between Elevations

A TIN by default has a single elevation dataset, but additional datasets can be created, such as flood depth and water surface elevation datasets when delineating a flood plain. For more information on datasets see Datasets.

TIN Dataset Righ-Click Menu

TIN dataset right-click menu

Right-clicking on a dataset of a TIN allows the following options:

  • Rename: Changes the name of the dataset in the Project Explorer.
  • Export Dataset: Selects the file format and save the dataset.
  • Delete: Removes the dataset from the TIN.
  • Properties: Brings up the Properties window for the dataset.
  • View Values: Opens the Edit Dataset Values dialog.
  • Contour Options: Brings up the Contour Options dialog.
  • Set as Elevations: Assigns the dataset as the elevation dataset for the TIN.

DEM Object Right-Click Menu

Right-clicking on a DEM DEM Data icon in Project Explorer.png allows selecting any of the DEM processing or visualization options in WMS. All DEMs are created by either reading a file or converting from another data object, such as a TIN or from raster GIS data. If multiple DEMs exist, these DEMs can be selected and merged together into a single DEM. There is only one active DEM. This active DEM is used for watershed delineation and for all other processes that require elevation data in WMS. A DEM raster can be cropped with a freehand polygon by selecting the Trim | Polygon option.
