A project in ET Terrain
Viewer is the current set of loaded layers with their properties.
You can save your work in a project and open it later. When you
start ET Terrain Viewer, an empty project is automatically created.
The first layer in a project must be a terrain layer. This is either
a raster file, or a TIN file of type Polygon with Z values, where
polygons have three vertices. See supported Data Formats for more
information.
The Project Manager displays a list of all currently loaded layers.
Layers are rendered in reverse order, i.e. the bottom layer is
rendered first, and the top layer is rendered last.
You can perform the following tasks:
- Exclude a layer from
rendering
Uncheck the check box next to the layer to exclude it from the
scene. Check the box to render it again.
- Change the order of layers
Layers are rendered in reverse order. Use drag and drop to
reorder layers. Drag a layer to its new location upper or lower
in the list and drop it there.
- Remove one or more selected
layer from the current project
Click command Remove from the context menu to remove the
selected layer(s).
- Zoom to selected layer(s)
Click command Zoom to layer from the context menu. The command
will zoom to the selected layer. If multiple layers are
selected, the command will zoom to the union extent of the
selected layers.
- Zoom to all layers in the
project
Click command Zoom to all from the context menu to zoom to the
union extent of all layers in the project.
- Set layer properties
Click command Properties from the context menu to open the
dialog with the properties of the selected layer.
NOTE: In order to avoid incorrect data display all the
layers loaded in a single project need to have the same
coordinate system and fall within the same extent.
