WMS:Project Explorer Contents for Terrain Data Module

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 allows a user to create a New folder or TIN. Because TINs can be created by digitizing in WMS, users can create a new, blank TIN. However, DEMs are only created by opening a DEM file type. If neither a TIN nor a DEM exists, then a user can also perform a Reprojection 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.

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
  • 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&rarr2D 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: Lets the user import a scalar dataset by first letting the using select the type of scalar dataset to import and then launching the Open dialog.
  • Save As
  • Properties
  • Display Options
  • Delete
  • Duplicate
  • Rename
  • Reprojection
  • Zoom To Layer
  • Metadata
  • 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

Right-clicking on a dataset of a TIN allows the user to Delete, Export, Rename, view Properties, View values, set the dataset as elevations, or set the dataset contour options.

DEM Object Right-Click Menu

Right-clicking on a DEM allows a user to select 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.
