ET Terrain Viewer allows you to view your GIS data in 3 dimensions.  You can load in the viewer Raster or TIN surfaces, Z enabled features and even plain 2D features by draping them on an existing surface. Then you can navigate through the 3D environment using several different navigation techniques.

Main features of ET Terrain Viewer are:

• Simple and intuitive user interface.
  The software was designed to be immediately intuitive and easy to learn
• Hardware-accelerated 3D visualization.
  ET Terrain Viewer utilizes the available graphics hardware to provide better performance.  Rendering is performed using Direct3D.  A graphics card with hardware transformation and lighting (T&L) is recommended.
• Mini-map of the loaded terrain.
  An interactive mini-map with an overview of the terrain, showing the position and looking direction of the observer.
• Multiple layer support.
  ET Terrain Viewer can load and display multiple raster and / or shape files simultaneously.
• Layer manipulation:
  • User-defined elevation, drape layer over terrain
  • Extrusion
  • Z-scale
  • Resolution reduction for increased performance.
  • Symbology supports gradient colors and textures based on elevation or custom attributes
  • Customizable point-markers for point layers
• Navigation using both mouse and keyboard
• Tools:
  • Identify space coordinates and elevation
  • Walking over the terrain at user-defined offset from the ground
  • Define a route and have the observer follow it automatically
  • Dynamic symbols in graphic layer
  • Customizable lights, skyboxes and fog effects
• Export to popular graphics formats - JPEG, PNG, BMP.
  Save a snapshot of the 3D image as a picture.

ET Terrain Viewer is a single-document application, and you can work with only one project at a time.  ET Terrain Viewer starts with an empty project.  To add layers to your project, click Add Layer from menu Layers.  Note that the first layer you add to a project must be a terrain layer - raster grid or TIN shape file.  To open an existing project, click Open Project from menu File.
